 ipfs-swarm is an abstraction for the network layer on IPFS. It offers an API to open streams between peers on a specific protocol.

+Ref spec (still a WiP) - https://github.com/diasdavid/specs/blob/protocol-spec/protocol/layers.md#network-layer
 
 # Usage
 
-## API calls
+### Create a new Swarm
 
-.openStream
-.registerHandle
+```javascript
+var Swarm = require('ipfs-swarm')
 
-## Events emmited
+var s = new Swarm([port]) // `port` defalts to 4001
+```
 
+### Set the swarm to listen for incoming streams
+
+```javascript
+s.listen([port], [callback]) // `port` defaults to 4001, `callback` gets called when the socket starts listening
+```
+
+### Close the listener/socket and every open stream that was multiplexed on it
+
+```javascript
+s.closeListener()
+```
+
+### Register a protocol to be handled by an incoming stream
+
+```javascript
+s.registerHandler('/name/protocol/you/want/version', function (stream) {})
+```
+
+### Dial a new stream
+
+```
+s.openStream(peerInfo, protocol, function (err, stream) {})
+```
+
+peerInfo must be a [`ipfs-peer`](https://www.npmjs.com/package/ipfs-peer) object, contaning both peer-id and multiaddrs.
+
+## Events emitted
+
+```
 .on('error')
 
 .on('connection')
-.on('connection-unknown')
+.on('connection-unknown') // used by Identify to start the Identify protocol from listener to dialer
+```
+
+## Identify protocol
+
+The Identify protocol is an integral part to Swarm. It enables peers to share observedAddrs, identities and other possible address available. This enables us to do better NAT traversal.
+
+To instantiate Identify:
+
+```
+var Identify = require('ipfs-swarm/identify')
+
+var i = new Identify(swarmInstance, peerSelf)
+```
+
+`swarmInstance` must be an Instance of swarm and `peerSelf` must be a instance of `ipfs-peer` that represents the peer that instantiated this Identify
 
-.on('stream')
-.on('stream-unknown')
+Identify emits a `peer-update` event each time it receives information from another peer.

-> IPFS swarm implementation in Node.js
+> libp2p swarm implementation in Node.js
 
 # Description
 
-ipfs-swarm is an abstraction for the network layer on IPFS. It offers an API to open streams between peers on a specific protocol.
+libp2p-swarm is connection abstraction that is able to leverage several transports and connection upgrades (such as congestion control, encrypt a channel, multiplex several streams in one connection, and more. It does this by bringing protocol multiplexing to the application level (instead of the traditional Port level) using multicodec and multistream.
 
-Ref spec (WIP) - https://github.com/diasdavid/specs/blob/protocol-spec/protocol/layers.md#network-layer
+libp2p-swarm is used by libp2p but it can be also used as a standalone module.
 
 # Usage
 
-### Create a new Swarm
+### Install and create a Swarm
 
-```javascript
-var Swarm = require('ipfs-swarm')
+libp2p-swarm is available on npm and so, like any other npm module, just:
 
-var s = new Swarm([port]) // `port` defalts to 4001
+```bash
+$ npm install libp2p-swarm --save
 ```
 
-### Set the swarm to listen for incoming streams
+And use it on your Node.js code as:
 
-```javascript
-s.listen([port], [callback]) // `port` defaults to 4001, `callback` gets called when the socket starts listening
-```
-
-### Close the listener/socket and every open stream that was multiplexed on it
+```JavaScript
+var Swarm = require('libp2p-swarm')
 
-```javascript
-s.closeListener()
+var sw = new Swarm(peerInfoSelf)
 ```
 
-### Register a protocol to be handled by an incoming stream
-
-```javascript
-s.registerHandler('/name/protocol/you/want/version', function (stream) {})
-```
+peerInfoSelf is a PeerInfo object that represents the peer creating this swarm instance.
 
-### Open a new connection
+### Support a transport
 
-Used when we want to make sure we can connect to a given peer, but do not intend to establish a stream with any of the services offered right away.
+libp2p-swarm expects transports that implement [abstract-transport](https://github.com/diasdavid/abstract-transport). For example [libp2p-tcp](https://github.com/diasdavid/node-libp2p-tcp), a simple shim on top of the `net` module to make it work with swarm expectations.
 
-```
-s.openConnection(peerConnection, function (err) {})
+```JavaScript
+sw.addTransport(transport, [options, dialOptions, listenOptions])
 ```
 
+### Add an connection upgrade
 
-### Dial a new stream
+A connection upgrade must be able to receive and return something that implements the [abstract-connection]() interface.
 
+```JavaScript
+sw.addUpgrade(connUpgrade, [options])
 ```
-s.openStream(peerInfo, protocol, function (err, stream) {})
-```
-
-peerInfo must be a [`ipfs-peer`](https://www.npmjs.com/package/ipfs-peer) object, contaning both peer-id and multiaddrs.
 
-## Events emitted
+Upgrading a connection to use a Stream Muxer is still considered a upgrade, but a special case since once this connection is applied, the returned obj will implement the [abstract-stream-muxer]() interface.
 
+```JavaScript
+sw.addStreamMuxer(streamMuxer, [options])
 ```
-.on('error')
 
-.on('connection')
-.on('connection-unknown') // used by Identify to start the Identify protocol from listener to dialer
-```
-
-## Identify protocol
-
-The Identify protocol is an integral part to Swarm. It enables peers to share observedAddrs, identities and other possible address available. This enables us to do better NAT traversal.
-
-To instantiate Identify:
+### Dial to another peer
 
+```JavaScript
+sw.dial(PeerInfo, protocol, options)
+sw.dial(PeerInfo, options) 
 ```
-var Identify = require('ipfs-swarm/identify')
 
-var i = new Identify(swarmInstance, peerSelf)
-```
+dial uses the best transport (whatever works first, in the future we can have some criteria), and jump starts the connection until the point we have to negotiate the protocol. If a Muxer is available, then drop the muxer onto that connection. Good to warm up connections or to check for connectivity. If we have already a Muxer for that peerInfo, than do nothing.
 
-`swarmInstance` must be an Instance of swarm and `peerSelf` must be a instance of `ipfs-peer` that represents the peer that instantiated this Identify
+### Accept requests on a specific protocol
 
-Identify emits a `peer-update` event each time it receives information from another peer.
+```JavaScript
+sw.handleProtocol(protocol, handlerFunction)
+```

Subject: [PATCH 073/634] Do not allow undefined `peerInfo`

# What

The code assumes that `peerInfo` exists, the API doesn't.

# How to test

```js
swarm = new Swarm()
swarm.addTransport('tcp', tcp, { multiaddr: mh }, {}, {port: 8095})
```

This shouldn't explode because of `self.peerInfo.multiaddrs`.

Subject: [PATCH 074/634] Protect from peers without supported transports

# What

Trying to run compliance tests from the kad router module. I've tried to port the new swarm API but forgot to add a transport. The tests ended up blowing up instead of failing gracefully.

# How to test

```js
peerOne = new Peer(Id.create(), [multiaddr('/ip4/127.0.0.1/tcp/8090')])
peerTwo = new Peer(Id.create(), [multiaddr('/ip4/127.0.0.1/tcp/8091')])
swarm = new Swarm(peerZero)
swarm.dial(peerTwo, {}, function (err) {
  console.log(err);
});
```

This just work and display the error.

 dial uses the best transport (whatever works first, in the future we can have some criteria), and jump starts the connection until the point we have to negotiate the protocol. If a muxer is available, then drop the muxer onto that connection. Good to warm up connections or to check for connectivity. If we have already a muxer for that peerInfo, than do nothing.

+# Design
+
+## Multitransport
+
+libp2p is designed to support multiple transports at the same time. While peers are identified by their ID (which are generated from their public keys), the addresses of each pair may vary, depending the device where they are being run or the network in which they are accessible through.
+
+In order for a transport to be supported, it has to follow the [interface-transport](https://github.com/diasdavid/interface-transport) spec.
+
+## Connection upgrades
+
+Each connection in libp2p follows the [interface-connection](https://github.com/diasdavid/interface-connection) spec. This design decision enables libp2p to have upgradable transports.
+
+We think of `upgrade` as a very important notion when we are talking about connections, we can see mechanisms like: stream multiplexing, congestion control, encrypted channels, multipath, simulcast, etc, as `upgrades` to a connection. A connection can be a simple and with no guarantees, drop a packet on the network with a destination thing, a transport in the other hand can be a connection and or a set of different upgrades that are mounted on top of each other, giving extra functionality to that connection and therefore `upgrading` it.
+
+Types of upgrades to a connection:
+
+- encrypted channel (with TLS for e.g)
+- congestion flow (some transports don't have it by default)
+- multipath (open several connections and abstract it as a single connection)
+- simulcast (still really thinking this one through, it might be interesting to send a packet through different connections under some hard network circumstances)
+- stream-muxer - this a special case, because once we upgrade a connection to a stream-muxer, we can open more streams (multiplex them) on a single stream, also enabling us to reuse the underlying dialed transport
+
+We also want to enable flexibility when it comes to upgrading a connection, for example, we might that all dialed transports pass through the encrypted channel upgrade, but not the congestion flow, specially when a transport might have already some underlying properties (UDP vs TCP vs WebRTC vs every other transport protocol)
+
+## Identify
+
+Identify is a protocol that Swarms mounts on top of itself, to identify the connections between any two peers. E.g:
+
+- a) peer A dials a conn to peer B
+- b) that conn gets upgraded to a stream multiplexer that both peers agree
+- c) peer B executes de identify protocol
+- d) peer B now can open streams to peer A, knowing which is the identity of peer A
+
+In addition to this, we also share the 'observed addresses' by the other peer, which is extremely useful information for different kinds of network topologies.
+
+## Notes
+
+To avoid the confusion between connection, stream, transport, and other names that represent an abstraction of data flow between two points, we use terms as:
+
+- connection - something that implements the transversal expectations of a stream between two peers, including the benefits of using a stream plus having a way to do half duplex, full duplex
+- transport - something that as a dial/listen interface and return objs that implement a connection interface

+ * Performs initialization, ie: precomputes tables to optimize for speed.
+ *
+ * One way to understand how AES works is to imagine that 'addition' and
+ * 'multiplication' are interfaces that require certain mathematical
+ * properties to hold true (ie: they are associative) but they might have
+ * different implementations and produce different kinds of results ...
+ * provided that their mathematical properties remain true. AES defines
+ * its own methods of addition and multiplication but keeps some important
+ * properties the same, ie: associativity and distributivity. The
+ * explanation below tries to shed some light on how AES defines addition
+ * and multiplication of bytes and 32-bit words in order to perform its
+ * encryption and decryption algorithms.
+ *
+ * The basics:
+ *
+ * The AES algorithm views bytes as binary representations of polynomials
+ * that have either 1 or 0 as the coefficients. It defines the addition
+ * or subtraction of two bytes as the XOR operation. It also defines the
+ * multiplication of two bytes as a finite field referred to as GF(2^8)
+ * (Note: 'GF' means "Galois Field" which is a field that contains a finite
+ * number of elements so GF(2^8) has 256 elements).
+ *
+ * This means that any two bytes can be represented as binary polynomials;
+ * when they multiplied together and modularly reduced by an irreducible
+ * polynomial of the 8th degree, the results are the field GF(2^8). The
+ * specific irreducible polynomial that AES uses in hexadecimal is 0x11b.
+ * This multiplication is associative with 0x01 as the identity:
+ *
+ * (b * 0x01 = GF(b, 0x01) = b).
+ *
+ * The operation GF(b, 0x02) can be performed at the byte level by left
+ * shifting b once and then XOR'ing it (to perform the modular reduction)
+ * with 0x11b if b is >= 128. Repeated application of the multiplication
+ * of 0x02 can be used to implement the multiplication of any two bytes.
+ *
+ * For instance, multiplying 0x57 and 0x13, denoted as GF(0x57, 0x13), can
+ * be performed by factoring 0x13 into 0x01, 0x02, and 0x10. Then these
+ * factors can each be multiplied by 0x57 and then added together. To do
+ * the multiplication, values for 0x57 multiplied by each of these 3 factors
+ * can be precomputed and stored in a table. To add them, the values from
+ * the table are XOR'd together.
+ *
+ * AES also defines addition and multiplication of words, that is 4-byte
+ * numbers represented as polynomials of 3 degrees where the coefficients
+ * are the values of the bytes.
+ *
+ * The word [a0, a1, a2, a3] is a polynomial a3x^3 + a2x^2 + a1x + a0.
+ *
+ * Addition is performed by XOR'ing like powers of x. Multiplication
+ * is performed in two steps, the first is an algebriac expansion as
+ * you would do normally (where addition is XOR). But the result is
+ * a polynomial larger than 3 degrees and thus it cannot fit in a word. So
+ * next the result is modularly reduced by an AES-specific polynomial of
+ * degree 4 which will always produce a polynomial of less than 4 degrees
+ * such that it will fit in a word. In AES, this polynomial is x^4 + 1.
+ *
+ * The modular product of two polynomials 'a' and 'b' is thus:
+ *
+ * d(x) = d3x^3 + d2x^2 + d1x + d0
+ * with
+ * d0 = GF(a0, b0) ^ GF(a3, b1) ^ GF(a2, b2) ^ GF(a1, b3)
+ * d1 = GF(a1, b0) ^ GF(a0, b1) ^ GF(a3, b2) ^ GF(a2, b3)
+ * d2 = GF(a2, b0) ^ GF(a1, b1) ^ GF(a0, b2) ^ GF(a3, b3)
+ * d3 = GF(a3, b0) ^ GF(a2, b1) ^ GF(a1, b2) ^ GF(a0, b3)
+ *
+ * As a matrix:
+ *
+ * [d0] = [a0 a3 a2 a1][b0]
+ * [d1]   [a1 a0 a3 a2][b1]
+ * [d2]   [a2 a1 a0 a3][b2]
+ * [d3]   [a3 a2 a1 a0][b3]
+ *
+ * Special polynomials defined by AES (0x02 == {02}):
+ * a(x)    = {03}x^3 + {01}x^2 + {01}x + {02}
+ * a^-1(x) = {0b}x^3 + {0d}x^2 + {09}x + {0e}.
+ *
+ * These polynomials are used in the MixColumns() and InverseMixColumns()
+ * operations, respectively, to cause each element in the state to affect
+ * the output (referred to as diffusing).
+ *
+ * RotWord() uses: a0 = a1 = a2 = {00} and a3 = {01}, which is the
+ * polynomial x3.
+ *
+ * The ShiftRows() method modifies the last 3 rows in the state (where
+ * the state is 4 words with 4 bytes per word) by shifting bytes cyclically.
+ * The 1st byte in the second row is moved to the end of the row. The 1st
+ * and 2nd bytes in the third row are moved to the end of the row. The 1st,
+ * 2nd, and 3rd bytes are moved in the fourth row.
+ *
+ * More details on how AES arithmetic works:
+ *
+ * In the polynomial representation of binary numbers, XOR performs addition
+ * and subtraction and multiplication in GF(2^8) denoted as GF(a, b)
+ * corresponds with the multiplication of polynomials modulo an irreducible
+ * polynomial of degree 8. In other words, for AES, GF(a, b) will multiply
+ * polynomial 'a' with polynomial 'b' and then do a modular reduction by
+ * an AES-specific irreducible polynomial of degree 8.
+ *
+ * A polynomial is irreducible if its only divisors are one and itself. For
+ * the AES algorithm, this irreducible polynomial is:
+ *
+ * m(x) = x^8 + x^4 + x^3 + x + 1,
+ *
+ * or {01}{1b} in hexadecimal notation, where each coefficient is a bit:
+ * 100011011 = 283 = 0x11b.
+ *
+ * For example, GF(0x57, 0x83) = 0xc1 because
+ *
+ * 0x57 = 87  = 01010111 = x^6 + x^4 + x^2 + x + 1
+ * 0x85 = 131 = 10000101 = x^7 + x + 1
+ *
+ * (x^6 + x^4 + x^2 + x + 1) * (x^7 + x + 1)
+ * =  x^13 + x^11 + x^9 + x^8 + x^7 +
+ *    x^7 + x^5 + x^3 + x^2 + x +
+ *    x^6 + x^4 + x^2 + x + 1
+ * =  x^13 + x^11 + x^9 + x^8 + x^6 + x^5 + x^4 + x^3 + 1 = y
+ *    y modulo (x^8 + x^4 + x^3 + x + 1)
+ * =  x^7 + x^6 + 1.
+ *
+ * The modular reduction by m(x) guarantees the result will be a binary
+ * polynomial of less than degree 8, so that it can fit in a byte.
+ *
+ * The operation to multiply a binary polynomial b with x (the polynomial
+ * x in binary representation is 00000010) is:
+ *
+ * b_7x^8 + b_6x^7 + b_5x^6 + b_4x^5 + b_3x^4 + b_2x^3 + b_1x^2 + b_0x^1
+ *
+ * To get GF(b, x) we must reduce that by m(x). If b_7 is 0 (that is the
+ * most significant bit is 0 in b) then the result is already reduced. If
+ * it is 1, then we can reduce it by subtracting m(x) via an XOR.
+ *
+ * It follows that multiplication by x (00000010 or 0x02) can be implemented
+ * by performing a left shift followed by a conditional bitwise XOR with
+ * 0x1b. This operation on bytes is denoted by xtime(). Multiplication by
+ * higher powers of x can be implemented by repeated application of xtime().
+ *
+ * By adding intermediate results, multiplication by any constant can be
+ * implemented. For instance:
+ *
+ * GF(0x57, 0x13) = 0xfe because:
+ *
+ * xtime(b) = (b & 128) ? (b << 1 ^ 0x11b) : (b << 1)
+ *
+ * Note: We XOR with 0x11b instead of 0x1b because in javascript our
+ * datatype for b can be larger than 1 byte, so a left shift will not
+ * automatically eliminate bits that overflow a byte ... by XOR'ing the
+ * overflow bit with 1 (the extra one from 0x11b) we zero it out.
+ *
+ * GF(0x57, 0x02) = xtime(0x57) = 0xae
+ * GF(0x57, 0x04) = xtime(0xae) = 0x47
+ * GF(0x57, 0x08) = xtime(0x47) = 0x8e
+ * GF(0x57, 0x10) = xtime(0x8e) = 0x07
+ *
+ * GF(0x57, 0x13) = GF(0x57, (0x01 ^ 0x02 ^ 0x10))
+ *
+ * And by the distributive property (since XOR is addition and GF() is
+ * multiplication):
+ *
+ * = GF(0x57, 0x01) ^ GF(0x57, 0x02) ^ GF(0x57, 0x10)
+ * = 0x57 ^ 0xae ^ 0x07
+ * = 0xfe.

+    /* We need to generate the SubBytes() sbox and isbox tables so that
+      we can perform byte substitutions. This requires us to traverse
+      all of the elements in GF, find their multiplicative inverses,
+      and apply to each the following affine transformation:
+
+      bi' = bi ^ b(i + 4) mod 8 ^ b(i + 5) mod 8 ^ b(i + 6) mod 8 ^
+            b(i + 7) mod 8 ^ ci
+      for 0 <= i < 8, where bi is the ith bit of the byte, and ci is the
+      ith bit of a byte c with the value {63} or {01100011}.
+
+      It is possible to traverse every possible value in a Galois field
+      using what is referred to as a 'generator'. There are many
+      generators (128 out of 256): 3,5,6,9,11,82 to name a few. To fully
+      traverse GF we iterate 255 times, multiplying by our generator
+      each time.
+
+      On each iteration we can determine the multiplicative inverse for
+      the current element.
+
+      Suppose there is an element in GF 'e'. For a given generator 'g',
+      e = g^x. The multiplicative inverse of e is g^(255 - x). It turns
+      out that if use the inverse of a generator as another generator
+      it will produce all of the corresponding multiplicative inverses
+      at the same time. For this reason, we choose 5 as our inverse
+      generator because it only requires 2 multiplies and 1 add and its
+      inverse, 82, requires relatively few operations as well.
+
+      In order to apply the affine transformation, the multiplicative
+      inverse 'ei' of 'e' can be repeatedly XOR'd (4 times) with a
+      bit-cycling of 'ei'. To do this 'ei' is first stored in 's' and
+      'x'. Then 's' is left shifted and the high bit of 's' is made the
+      low bit. The resulting value is stored in 's'. Then 'x' is XOR'd
+      with 's' and stored in 'x'. On each subsequent iteration the same
+      operation is performed. When 4 iterations are complete, 'x' is
+      XOR'd with 'c' (0x63) and the transformed value is stored in 'x'.
+      For example:
+
+      s = 01000001
+      x = 01000001
+
+      iteration 1: s = 10000010, x ^= s
+      iteration 2: s = 00000101, x ^= s
+      iteration 3: s = 00001010, x ^= s
+      iteration 4: s = 00010100, x ^= s
+      x ^= 0x63
+
+      This can be done with a loop where s = (s << 1) | (s >> 7). However,
+      it can also be done by using a single 16-bit (in this case 32-bit)
+      number 'sx'. Since XOR is an associative operation, we can set 'sx'
+      to 'ei' and then XOR it with 'sx' left-shifted 1,2,3, and 4 times.
+      The most significant bits will flow into the high 8 bit positions
+      and be correctly XOR'd with one another. All that remains will be
+      to cycle the high 8 bits by XOR'ing them all with the lower 8 bits
+      afterwards.
+
+      At the same time we're populating sbox and isbox we can precompute
+      the multiplication we'll need to do to do MixColumns() later.
+    */
+
+    // apply affine transformation
+    sx = ei ^ (ei << 1) ^ (ei << 2) ^ (ei << 3) ^ (ei << 4);
+    sx = (sx >> 8) ^ (sx & 255) ^ 0x63;
+

+    sbox[e] = sx;
+    isbox[sx] = e;
+
+    /* Mixing columns is done using matrix multiplication. The columns
+      that are to be mixed are each a single word in the current state.
+      The state has Nb columns (4 columns). Therefore each column is a
+      4 byte word. So to mix the columns in a single column 'c' where
+      its rows are r0, r1, r2, and r3, we use the following matrix
+      multiplication:
+
+      [2 3 1 1]*[r0,c]=[r'0,c]
+      [1 2 3 1] [r1,c] [r'1,c]
+      [1 1 2 3] [r2,c] [r'2,c]
+      [3 1 1 2] [r3,c] [r'3,c]
+
+      r0, r1, r2, and r3 are each 1 byte of one of the words in the
+      state (a column). To do matrix multiplication for each mixed
+      column c' we multiply the corresponding row from the left matrix
+      with the corresponding column from the right matrix. In total, we
+      get 4 equations:
+
+      r0,c' = 2*r0,c + 3*r1,c + 1*r2,c + 1*r3,c
+      r1,c' = 1*r0,c + 2*r1,c + 3*r2,c + 1*r3,c
+      r2,c' = 1*r0,c + 1*r1,c + 2*r2,c + 3*r3,c
+      r3,c' = 3*r0,c + 1*r1,c + 1*r2,c + 2*r3,c
+
+      As usual, the multiplication is as previously defined and the
+      addition is XOR. In order to optimize mixing columns we can store
+      the multiplication results in tables. If you think of the whole
+      column as a word (it might help to visualize by mentally rotating
+      the equations above by counterclockwise 90 degrees) then you can
+      see that it would be useful to map the multiplications performed on
+      each byte (r0, r1, r2, r3) onto a word as well. For instance, we
+      could map 2*r0,1*r0,1*r0,3*r0 onto a word by storing 2*r0 in the
+      highest 8 bits and 3*r0 in the lowest 8 bits (with the other two
+      respectively in the middle). This means that a table can be
+      constructed that uses r0 as an index to the word. We can do the
+      same with r1, r2, and r3, creating a total of 4 tables.
+
+      To construct a full c', we can just look up each byte of c in
+      their respective tables and XOR the results together.
+
+      Also, to build each table we only have to calculate the word
+      for 2,1,1,3 for every byte ... which we can do on each iteration
+      of this loop since we will iterate over every byte. After we have
+      calculated 2,1,1,3 we can get the results for the other tables
+      by cycling the byte at the end to the beginning. For instance
+      we can take the result of table 2,1,1,3 and produce table 3,2,1,1
+      by moving the right most byte to the left most position just like
+      how you can imagine the 3 moved out of 2,1,1,3 and to the front
+      to produce 3,2,1,1.
+
+      There is another optimization in that the same multiples of
+      the current element we need in order to advance our generator
+      to the next iteration can be reused in performing the 2,1,1,3
+      calculation. We also calculate the inverse mix column tables,
+      with e,9,d,b being the inverse of 2,1,1,3.
+
+      When we're done, and we need to actually mix columns, the first
+      byte of each state word should be put through mix[0] (2,1,1,3),
+      the second through mix[1] (3,2,1,1) and so forth. Then they should
+      be XOR'd together to produce the fully mixed column.

+   /* When we are updating a cipher block we always use the code path for

+     are differences in the decryption algorithm, other than just swapping
+     in different look up tables, we must transform our key schedule to
+     account for these changes:
+
+     1. The decryption algorithm gets its key rounds in reverse order.
+     2. The decryption algorithm adds the round key before mixing columns
+       instead of afterwards.
+
+     We don't need to modify our key schedule to handle the first case,
+     we can just traverse the key schedule in reverse order when decrypting.
+
+     The second case requires a little work.
+
+     The tables we built for performing rounds will take an input and then
+     perform SubBytes() and MixColumns() or, for the decrypt version,
+     InvSubBytes() and InvMixColumns(). But the decrypt algorithm requires
+     us to AddRoundKey() before InvMixColumns(). This means we'll need to
+     apply some transformations to the round key to inverse-mix its columns
+     so they'll be correct for moving AddRoundKey() to after the state has
+     had its columns inverse-mixed.
+
+     To inverse-mix the columns of the state when we're decrypting we use a
+     lookup table that will apply InvSubBytes() and InvMixColumns() at the
+     same time. However, the round key's bytes are not inverse-substituted
+     in the decryption algorithm. To get around this problem, we can first
+     substitute the bytes in the round key so that when we apply the
+     transformation via the InvSubBytes()+InvMixColumns() table, it will
+     undo our substitution leaving us with the original value that we
+     want -- and then inverse-mix that value.
+
+     This change will correctly alter our key schedule so that we can XOR
+     each round key with our already transformed decryption state. This
+     allows us to use the same code path as the encryption algorithm.
+
+     We make one more change to the decryption key. Since the decryption
+     algorithm runs in reverse from the encryption algorithm, we reverse
+     the order of the round keys to avoid having to iterate over the key
+     schedule backwards when running the encryption algorithm later in
+     decryption mode. In addition to reversing the order of the round keys,
+     we also swap each round key's 2nd and 4th rows. See the comments
+     section where rounds are performed for more details about why this is
+     done. These changes are done inline with the other substitution
+     described above.

+      mix a column, we perform these transformations on each row in c,
+      which is 1 byte in each word. The new column for c0 is c'0:
+
+               m0      m1      m2      m3
+      r0,c'0 = 2*r0,c0 + 3*r1,c0 + 1*r2,c0 + 1*r3,c0

+      8 bits and r3 being its lower 8 bits:
+
+      m0[c0 >> 24] will yield this word: [2*r0,1*r0,1*r0,3*r0]
+      ...
+      m3[c0 & 255] will yield this word: [1*r3,1*r3,3*r3,2*r3]
+
+      Therefore to mix the columns in each word in the state we

+      c'0,r3 = m0[c0 >> 24] ^ m1[c1 >> 16] ^ m2[c2 >> 8] ^ m3[c3]
+
+      However, before mixing, the algorithm requires us to perform
+      ShiftRows(). The ShiftRows() transformation cyclically shifts the
+      last 3 rows of the state over different offsets. The first row
+      (r = 0) is not shifted.
+
+      s'_r,c = s_r,(c + shift(r, Nb) mod Nb
+      for 0 < r < 4 and 0 <= c < Nb and
+      shift(1, 4) = 1
+      shift(2, 4) = 2
+      shift(3, 4) = 3.
+
+      This causes the first byte in r = 1 to be moved to the end of
+      the row, the first 2 bytes in r = 2 to be moved to the end of
+      the row, the first 3 bytes in r = 3 to be moved to the end of
+      the row:
+
+      r1: [c0 c1 c2 c3] => [c1 c2 c3 c0]
+      r2: [c0 c1 c2 c3]    [c2 c3 c0 c1]
+      r3: [c0 c1 c2 c3]    [c3 c0 c1 c2]
+
+      We can make these substitutions inline with our column mixing to
+      generate an updated set of equations to produce each word in the
+      state (note the columns have changed positions):
+
+      c0 c1 c2 c3 => c0 c1 c2 c3
+      c0 c1 c2 c3    c1 c2 c3 c0  (cycled 1 byte)
+      c0 c1 c2 c3    c2 c3 c0 c1  (cycled 2 bytes)
+      c0 c1 c2 c3    c3 c0 c1 c2  (cycled 3 bytes)
+
+      Therefore:
+
+      c'0 = 2*r0,c0 + 3*r1,c1 + 1*r2,c2 + 1*r3,c3
+      c'0 = 1*r0,c0 + 2*r1,c1 + 3*r2,c2 + 1*r3,c3
+      c'0 = 1*r0,c0 + 1*r1,c1 + 2*r2,c2 + 3*r3,c3
+      c'0 = 3*r0,c0 + 1*r1,c1 + 1*r2,c2 + 2*r3,c3
+
+      c'1 = 2*r0,c1 + 3*r1,c2 + 1*r2,c3 + 1*r3,c0
+      c'1 = 1*r0,c1 + 2*r1,c2 + 3*r2,c3 + 1*r3,c0
+      c'1 = 1*r0,c1 + 1*r1,c2 + 2*r2,c3 + 3*r3,c0
+      c'1 = 3*r0,c1 + 1*r1,c2 + 1*r2,c3 + 2*r3,c0
+
+      ... and so forth for c'2 and c'3. The important distinction is
+      that the columns are cycling, with c0 being used with the m0
+      map when calculating c0, but c1 being used with the m0 map when
+      calculating c1 ... and so forth.
+
+      When performing the inverse we transform the mirror image and
+      skip the bottom row, instead of the top one, and move upwards:
+
+      c3 c2 c1 c0 => c0 c3 c2 c1  (cycled 3 bytes) *same as encryption
+      c3 c2 c1 c0    c1 c0 c3 c2  (cycled 2 bytes)
+      c3 c2 c1 c0    c2 c1 c0 c3  (cycled 1 byte)  *same as encryption
+      c3 c2 c1 c0    c3 c2 c1 c0
+
+      If you compare the resulting matrices for ShiftRows()+MixColumns()
+      and for InvShiftRows()+InvMixColumns() the 2nd and 4th columns are
+      different (in encrypt mode vs. decrypt mode). So in order to use
+      the same code to handle both encryption and decryption, we will
+      need to do some mapping.
+
+      If in encryption mode we let a=c0, b=c1, c=c2, d=c3, and r<N> be
+      a row number in the state, then the resulting matrix in encryption
+      mode for applying the above transformations would be:
+
+      r1: a b c d
+      r2: b c d a
+      r3: c d a b
+      r4: d a b c
+
+      If we did the same in decryption mode we would get:
+
+      r1: a d c b
+      r2: b a d c
+      r3: c b a d
+      r4: d c b a
+
+      If instead we swap d and b (set b=c3 and d=c1), then we get:
+
+      r1: a b c d
+      r2: d a b c
+      r3: c d a b
+      r4: b c d a
+
+      Now the 1st and 3rd rows are the same as the encryption matrix. All
+      we need to do then to make the mapping exactly the same is to swap
+      the 2nd and 4th rows when in decryption mode. To do this without
+      having to do it on each iteration, we swapped the 2nd and 4th rows
+      in the decryption key schedule. We also have to do the swap above
+      when we first pull in the input and when we set the final output. */

+/**
+ * Javascript implementation of Abstract Syntax Notation Number One.
+ *
+ * @author Dave Longley
+ *
+ * Copyright (c) 2010-2015 Digital Bazaar, Inc.
+ *
+ * An API for storing data using the Abstract Syntax Notation Number One
+ * format using DER (Distinguished Encoding Rules) encoding. This encoding is
+ * commonly used to store data for PKI, i.e. X.509 Certificates, and this
+ * implementation exists for that purpose.
+ *
+ * Abstract Syntax Notation Number One (ASN.1) is used to define the abstract
+ * syntax of information without restricting the way the information is encoded
+ * for transmission. It provides a standard that allows for open systems
+ * communication. ASN.1 defines the syntax of information data and a number of
+ * simple data types as well as a notation for describing them and specifying
+ * values for them.
+ *
+ * The RSA algorithm creates public and private keys that are often stored in
+ * X.509 or PKCS#X formats -- which use ASN.1 (encoded in DER format). This
+ * class provides the most basic functionality required to store and load DSA
+ * keys that are encoded according to ASN.1.
+ *
+ * The most common binary encodings for ASN.1 are BER (Basic Encoding Rules)
+ * and DER (Distinguished Encoding Rules). DER is just a subset of BER that
+ * has stricter requirements for how data must be encoded.
+ *
+ * Each ASN.1 structure has a tag (a byte identifying the ASN.1 structure type)
+ * and a byte array for the value of this ASN1 structure which may be data or a
+ * list of ASN.1 structures.
+ *
+ * Each ASN.1 structure using BER is (Tag-Length-Value):
+ *
+ * | byte 0 | bytes X | bytes Y |
+ * |--------|---------|----------
+ * |  tag   | length  |  value  |
+ *
+ * ASN.1 allows for tags to be of "High-tag-number form" which allows a tag to
+ * be two or more octets, but that is not supported by this class. A tag is
+ * only 1 byte. Bits 1-5 give the tag number (ie the data type within a
+ * particular 'class'), 6 indicates whether or not the ASN.1 value is
+ * constructed from other ASN.1 values, and bits 7 and 8 give the 'class'. If
+ * bits 7 and 8 are both zero, the class is UNIVERSAL. If only bit 7 is set,
+ * then the class is APPLICATION. If only bit 8 is set, then the class is
+ * CONTEXT_SPECIFIC. If both bits 7 and 8 are set, then the class is PRIVATE.
+ * The tag numbers for the data types for the class UNIVERSAL are listed below:
+ *
+ * UNIVERSAL 0 Reserved for use by the encoding rules
+ * UNIVERSAL 1 Boolean type
+ * UNIVERSAL 2 Integer type
+ * UNIVERSAL 3 Bitstring type
+ * UNIVERSAL 4 Octetstring type
+ * UNIVERSAL 5 Null type
+ * UNIVERSAL 6 Object identifier type
+ * UNIVERSAL 7 Object descriptor type
+ * UNIVERSAL 8 External type and Instance-of type
+ * UNIVERSAL 9 Real type
+ * UNIVERSAL 10 Enumerated type
+ * UNIVERSAL 11 Embedded-pdv type
+ * UNIVERSAL 12 UTF8String type
+ * UNIVERSAL 13 Relative object identifier type
+ * UNIVERSAL 14-15 Reserved for future editions
+ * UNIVERSAL 16 Sequence and Sequence-of types
+ * UNIVERSAL 17 Set and Set-of types
+ * UNIVERSAL 18-22, 25-30 Character string types
+ * UNIVERSAL 23-24 Time types
+ *
+ * The length of an ASN.1 structure is specified after the tag identifier.
+ * There is a definite form and an indefinite form. The indefinite form may
+ * be used if the encoding is constructed and not all immediately available.
+ * The indefinite form is encoded using a length byte with only the 8th bit
+ * set. The end of the constructed object is marked using end-of-contents
+ * octets (two zero bytes).
+ *
+ * The definite form looks like this:
+ *
+ * The length may take up 1 or more bytes, it depends on the length of the
+ * value of the ASN.1 structure. DER encoding requires that if the ASN.1
+ * structure has a value that has a length greater than 127, more than 1 byte
+ * will be used to store its length, otherwise just one byte will be used.
+ * This is strict.
+ *
+ * In the case that the length of the ASN.1 value is less than 127, 1 octet
+ * (byte) is used to store the "short form" length. The 8th bit has a value of
+ * 0 indicating the length is "short form" and not "long form" and bits 7-1
+ * give the length of the data. (The 8th bit is the left-most, most significant
+ * bit: also known as big endian or network format).
+ *
+ * In the case that the length of the ASN.1 value is greater than 127, 2 to
+ * 127 octets (bytes) are used to store the "long form" length. The first
+ * byte's 8th bit is set to 1 to indicate the length is "long form." Bits 7-1
+ * give the number of additional octets. All following octets are in base 256
+ * with the most significant digit first (typical big-endian binary unsigned
+ * integer storage). So, for instance, if the length of a value was 257, the
+ * first byte would be set to:
+ *
+ * 10000010 = 130 = 0x82.
+ *
+ * This indicates there are 2 octets (base 256) for the length. The second and
+ * third bytes (the octets just mentioned) would store the length in base 256:
+ *
+ * octet 2: 00000001 = 1 * 256^1 = 256
+ * octet 3: 00000001 = 1 * 256^0 = 1
+ * total = 257
+ *
+ * The algorithm for converting a js integer value of 257 to base-256 is:
+ *
+ * var value = 257;
+ * var bytes = [];
+ * bytes[0] = (value >>> 8) & 0xFF; // most significant byte first
+ * bytes[1] = value & 0xFF;        // least significant byte last
+ *
+ * On the ASN.1 UNIVERSAL Object Identifier (OID) type:
+ *
+ * An OID can be written like: "value1.value2.value3...valueN"
+ *
+ * The DER encoding rules:
+ *
+ * The first byte has the value 40 * value1 + value2.
+ * The following bytes, if any, encode the remaining values. Each value is
+ * encoded in base 128, most significant digit first (big endian), with as
+ * few digits as possible, and the most significant bit of each byte set
+ * to 1 except the last in each value's encoding. For example: Given the
+ * OID "1.2.840.113549", its DER encoding is (remember each byte except the
+ * last one in each encoding is OR'd with 0x80):
+ *
+ * byte 1: 40 * 1 + 2 = 42 = 0x2A.
+ * bytes 2-3: 128 * 6 + 72 = 840 = 6 72 = 6 72 = 0x0648 = 0x8648
+ * bytes 4-6: 16384 * 6 + 128 * 119 + 13 = 6 119 13 = 0x06770D = 0x86F70D
+ *
+ * The final value is: 0x2A864886F70D.
+ * The full OID (including ASN.1 tag and length of 6 bytes) is:
+ * 0x06062A864886F70D

+  /* Chinese remainder theorem (CRT) states:
+
+    Suppose n1, n2, ..., nk are positive integers which are pairwise
+    coprime (n1 and n2 have no common factors other than 1). For any
+    integers x1, x2, ..., xk there exists an integer x solving the
+    system of simultaneous congruences (where ~= means modularly
+    congruent so a ~= b mod n means a mod n = b mod n):
+
+    x ~= x1 mod n1
+    x ~= x2 mod n2
+    ...
+    x ~= xk mod nk
+
+    This system of congruences has a single simultaneous solution x
+    between 0 and n - 1. Furthermore, each xk solution and x itself
+    is congruent modulo the product n = n1*n2*...*nk.
+    So x1 mod n = x2 mod n = xk mod n = x mod n.
+
+    The single simultaneous solution x can be solved with the following
+    equation:
+
+    x = sum(xi*ri*si) mod n where ri = n/ni and si = ri^-1 mod ni.
+
+    Where x is less than n, xi = x mod ni.
+
+    For RSA we are only concerned with k = 2. The modulus n = pq, where
+    p and q are coprime. The RSA decryption algorithm is:
+
+    y = x^d mod n
+
+    Given the above:
+
+    x1 = x^d mod p
+    r1 = n/p = q
+    s1 = q^-1 mod p
+    x2 = x^d mod q
+    r2 = n/q = p
+    s2 = p^-1 mod q
+
+    So y = (x1r1s1 + x2r2s2) mod n
+         = ((x^d mod p)q(q^-1 mod p) + (x^d mod q)p(p^-1 mod q)) mod n
+
+    According to Fermat's Little Theorem, if the modulus P is prime,
+    for any integer A not evenly divisible by P, A^(P-1) ~= 1 mod P.
+    Since A is not divisible by P it follows that if:
+    N ~= M mod (P - 1), then A^N mod P = A^M mod P. Therefore:
+
+    A^N mod P = A^(M mod (P - 1)) mod P. (The latter takes less effort
+    to calculate). In order to calculate x^d mod p more quickly the
+    exponent d mod (p - 1) is stored in the RSA private key (the same
+    is done for x^d mod q). These values are referred to as dP and dQ
+    respectively. Therefore we now have:
+
+    y = ((x^dP mod p)q(q^-1 mod p) + (x^dQ mod q)p(p^-1 mod q)) mod n
+
+    Since we'll be reducing x^dP by modulo p (same for q) we can also
+    reduce x by p (and q respectively) before hand. Therefore, let
+
+    xp = ((x mod p)^dP mod p), and
+    xq = ((x mod q)^dQ mod q), yielding:
+
+    y = (xp*q*(q^-1 mod p) + xq*p*(p^-1 mod q)) mod n
+
+    This can be further reduced to a simple algorithm that only
+    requires 1 inverse (the q inverse is used) to be used and stored.
+    The algorithm is called Garner's algorithm. If qInv is the
+    inverse of q, we simply calculate:
+
+    y = (qInv*(xp - xq) mod p) * q + xq
+
+    However, there are two further complications. First, we need to
+    ensure that xp > xq to prevent signed BigIntegers from being used
+    so we add p until this is true (since we will be mod'ing with
+    p anyway). Then, there is a known timing attack on algorithms
+    using the CRT. To mitigate this risk, "cryptographic blinding"
+    should be used. This requires simply generating a random number r
+    between 0 and n-1 and its inverse and multiplying x by r^e before
+    calculating y and then multiplying y by r^-1 afterwards. Note that
+    r must be coprime with n (gcd(r, n) === 1) in order to have an
+    inverse.

+  /* From: RFC3280 - Internet X.509 Public Key Infrastructure Certificate
+    Section 6: Certification Path Validation
+    See inline parentheticals related to this particular implementation.
+
+    The primary goal of path validation is to verify the binding between
+    a subject distinguished name or a subject alternative name and subject
+    public key, as represented in the end entity certificate, based on the
+    public key of the trust anchor. This requires obtaining a sequence of
+    certificates that support that binding. That sequence should be provided
+    in the passed 'chain'. The trust anchor should be in the given CA
+    store. The 'end entity' certificate is the certificate provided by the
+    end point (typically a server) and is the first in the chain.
+
+    To meet this goal, the path validation process verifies, among other
+    things, that a prospective certification path (a sequence of n
+    certificates or a 'chain') satisfies the following conditions:
+
+    (a) for all x in {1, ..., n-1}, the subject of certificate x is
+          the issuer of certificate x+1;
+
+    (b) certificate 1 is issued by the trust anchor;
+
+    (c) certificate n is the certificate to be validated; and
+
+    (d) for all x in {1, ..., n}, the certificate was valid at the
+          time in question.
+
+    Note that here 'n' is index 0 in the chain and 1 is the last certificate
+    in the chain and it must be signed by a certificate in the connection's
+    CA store.
+
+    The path validation process also determines the set of certificate
+    policies that are valid for this path, based on the certificate policies
+    extension, policy mapping extension, policy constraints extension, and
+    inhibit any-policy extension.
+
+    Note: Policy mapping extension not supported (Not Required).
+
+    Note: If the certificate has an unsupported critical extension, then it
+    must be rejected.
+
+    Note: A certificate is self-issued if the DNs that appear in the subject
+    and issuer fields are identical and are not empty.
+
+    The path validation algorithm assumes the following seven inputs are
+    provided to the path processing logic. What this specific implementation
+    will use is provided parenthetically:
+
+    (a) a prospective certification path of length n (the 'chain')
+    (b) the current date/time: ('now').
+    (c) user-initial-policy-set: A set of certificate policy identifiers
+          naming the policies that are acceptable to the certificate user.
+          The user-initial-policy-set contains the special value any-policy
+          if the user is not concerned about certificate policy
+          (Not implemented. Any policy is accepted).
+    (d) trust anchor information, describing a CA that serves as a trust
+          anchor for the certification path. The trust anchor information
+          includes:
+
+      (1)  the trusted issuer name,
+      (2)  the trusted public key algorithm,
+      (3)  the trusted public key, and
+      (4)  optionally, the trusted public key parameters associated
+             with the public key.
+
+      (Trust anchors are provided via certificates in the CA store).
+
+      The trust anchor information may be provided to the path processing
+      procedure in the form of a self-signed certificate. The trusted anchor
+      information is trusted because it was delivered to the path processing
+      procedure by some trustworthy out-of-band procedure. If the trusted
+      public key algorithm requires parameters, then the parameters are
+      provided along with the trusted public key (No parameters used in this
+      implementation).
+
+    (e) initial-policy-mapping-inhibit, which indicates if policy mapping is
+          allowed in the certification path.
+          (Not implemented, no policy checking)
+
+    (f) initial-explicit-policy, which indicates if the path must be valid
+          for at least one of the certificate policies in the user-initial-
+          policy-set.
+          (Not implemented, no policy checking)
+
+    (g) initial-any-policy-inhibit, which indicates whether the
+          anyPolicy OID should be processed if it is included in a
+          certificate.
+          (Not implemented, so any policy is valid provided that it is
+          not marked as critical) */
+
+  /* Basic Path Processing:
+
+    For each certificate in the 'chain', the following is checked:
+
+    1. The certificate validity period includes the current time.
+    2. The certificate was signed by its parent (where the parent is either
+       the next in the chain or from the CA store). Allow processing to
+       continue to the next step if no parent is found but the certificate is
+       in the CA store.
+    3. TODO: The certificate has not been revoked.
+    4. The certificate issuer name matches the parent's subject name.
+    5. TODO: If the certificate is self-issued and not the final certificate
+       in the chain, skip this step, otherwise verify that the subject name
+       is within one of the permitted subtrees of X.500 distinguished names
+       and that each of the alternative names in the subjectAltName extension
+       (critical or non-critical) is within one of the permitted subtrees for
+       that name type.
+    6. TODO: If the certificate is self-issued and not the final certificate
+       in the chain, skip this step, otherwise verify that the subject name
+       is not within one of the excluded subtrees for X.500 distinguished
+       names and none of the subjectAltName extension names are excluded for
+       that name type.
+    7. The other steps in the algorithm for basic path processing involve
+       handling the policy extension which is not presently supported in this
+       implementation. Instead, if a critical policy extension is found, the
+       certificate is rejected as not supported.
+    8. If the certificate is not the first or if its the only certificate in
+       the chain (having no parent from the CA store or is self-signed) and it
+       has a critical key usage extension, verify that the keyCertSign bit is
+       set. If the key usage extension exists, verify that the basic
+       constraints extension exists. If the basic constraints extension exists,
+       verify that the cA flag is set. If pathLenConstraint is set, ensure that
+       the number of certificates that precede in the chain (come earlier
+       in the chain as implemented below), excluding the very first in the
+       chain (typically the end-entity one), isn't greater than the
+       pathLenConstraint. This constraint limits the number of intermediate
+       CAs that may appear below a CA before only end-entity certificates

+ * A Javascript implementation of Transport Layer Security (TLS).
+ *
+ * @author Dave Longley
+ *
+ * Copyright (c) 2009-2014 Digital Bazaar, Inc.
+ *
+ * The TLS Handshake Protocol involves the following steps:
+ *
+ * - Exchange hello messages to agree on algorithms, exchange random values,
+ * and check for session resumption.
+ *
+ * - Exchange the necessary cryptographic parameters to allow the client and
+ * server to agree on a premaster secret.
+ *
+ * - Exchange certificates and cryptographic information to allow the client
+ * and server to authenticate themselves.
+ *
+ * - Generate a master secret from the premaster secret and exchanged random
+ * values.
+ *
+ * - Provide security parameters to the record layer.
+ *
+ * - Allow the client and server to verify that their peer has calculated the
+ * same security parameters and that the handshake occurred without tampering
+ * by an attacker.
+ *
+ * Up to 4 different messages may be sent during a key exchange. The server
+ * certificate, the server key exchange, the client certificate, and the
+ * client key exchange.
+ *
+ * A typical handshake (from the client's perspective).
+ *
+ * 1. Client sends ClientHello.
+ * 2. Client receives ServerHello.
+ * 3. Client receives optional Certificate.
+ * 4. Client receives optional ServerKeyExchange.
+ * 5. Client receives ServerHelloDone.
+ * 6. Client sends optional Certificate.
+ * 7. Client sends ClientKeyExchange.
+ * 8. Client sends optional CertificateVerify.
+ * 9. Client sends ChangeCipherSpec.
+ * 10. Client sends Finished.
+ * 11. Client receives ChangeCipherSpec.
+ * 12. Client receives Finished.
+ * 13. Client sends/receives application data.
+ *
+ * To reuse an existing session:
+ *
+ * 1. Client sends ClientHello with session ID for reuse.
+ * 2. Client receives ServerHello with same session ID if reusing.
+ * 3. Client receives ChangeCipherSpec message if reusing.
+ * 4. Client receives Finished.
+ * 5. Client sends ChangeCipherSpec.
+ * 6. Client sends Finished.
+ *
+ * Note: Client ignores HelloRequest if in the middle of a handshake.
+ *
+ * Record Layer:
+ *
+ * The record layer fragments information blocks into TLSPlaintext records
+ * carrying data in chunks of 2^14 bytes or less. Client message boundaries are
+ * not preserved in the record layer (i.e., multiple client messages of the
+ * same ContentType MAY be coalesced into a single TLSPlaintext record, or a
+ * single message MAY be fragmented across several records).
+ *
+ * struct {
+ *   uint8 major;
+ *   uint8 minor;
+ * } ProtocolVersion;
+ *
+ * struct {
+ *   ContentType type;
+ *   ProtocolVersion version;
+ *   uint16 length;
+ *   opaque fragment[TLSPlaintext.length];
+ * } TLSPlaintext;
+ *
+ * type:
+ *   The higher-level protocol used to process the enclosed fragment.
+ *
+ * version:
+ *   The version of the protocol being employed. TLS Version 1.2 uses version
+ *   {3, 3}. TLS Version 1.0 uses version {3, 1}. Note that a client that
+ *   supports multiple versions of TLS may not know what version will be
+ *   employed before it receives the ServerHello.
+ *
+ * length:
+ *   The length (in bytes) of the following TLSPlaintext.fragment. The length
+ *   MUST NOT exceed 2^14 = 16384 bytes.
+ *
+ * fragment:
+ *   The application data. This data is transparent and treated as an
+ *   independent block to be dealt with by the higher-level protocol specified
+ *   by the type field.
+ *
+ * Implementations MUST NOT send zero-length fragments of Handshake, Alert, or
+ * ChangeCipherSpec content types. Zero-length fragments of Application data
+ * MAY be sent as they are potentially useful as a traffic analysis
+ * countermeasure.
+ *
+ * Note: Data of different TLS record layer content types MAY be interleaved.
+ * Application data is generally of lower precedence for transmission than
+ * other content types. However, records MUST be delivered to the network in
+ * the same order as they are protected by the record layer. Recipients MUST
+ * receive and process interleaved application layer traffic during handshakes
+ * subsequent to the first one on a connection.
+ *
+ * struct {
+ *   ContentType type;       // same as TLSPlaintext.type
+ *   ProtocolVersion version;// same as TLSPlaintext.version
+ *   uint16 length;
+ *   opaque fragment[TLSCompressed.length];
+ * } TLSCompressed;
+ *
+ * length:
+ *   The length (in bytes) of the following TLSCompressed.fragment.
+ *   The length MUST NOT exceed 2^14 + 1024.
+ *
+ * fragment:
+ *   The compressed form of TLSPlaintext.fragment.
+ *
+ * Note: A CompressionMethod.null operation is an identity operation; no fields
+ * are altered. In this implementation, since no compression is supported,
+ * uncompressed records are always the same as compressed records.
+ *
+ * Encryption Information:
+ *
+ * The encryption and MAC functions translate a TLSCompressed structure into a
+ * TLSCiphertext. The decryption functions reverse the process. The MAC of the
+ * record also includes a sequence number so that missing, extra, or repeated
+ * messages are detectable.
+ *
+ * struct {
+ *   ContentType type;
+ *   ProtocolVersion version;
+ *   uint16 length;
+ *   select (SecurityParameters.cipher_type) {

+ *     case block:  GenericBlockCipher;
+ *     case aead:   GenericAEADCipher;
+ *   } fragment;
+ * } TLSCiphertext;
+ *
+ * type:
+ *   The type field is identical to TLSCompressed.type.
+ *
+ * version:
+ *   The version field is identical to TLSCompressed.version.
+ *
+ * length:
+ *   The length (in bytes) of the following TLSCiphertext.fragment.
+ *   The length MUST NOT exceed 2^14 + 2048.
+ *
+ * fragment:
+ *   The encrypted form of TLSCompressed.fragment, with the MAC.
+ *
+ * Note: Only CBC Block Ciphers are supported by this implementation.
+ *
+ * The TLSCompressed.fragment structures are converted to/from block
+ * TLSCiphertext.fragment structures.
+ *
+ * struct {
+ *   opaque IV[SecurityParameters.record_iv_length];
+ *   block-ciphered struct {
+ *     opaque content[TLSCompressed.length];
+ *     opaque MAC[SecurityParameters.mac_length];
+ *     uint8 padding[GenericBlockCipher.padding_length];
+ *     uint8 padding_length;
+ *   };
+ * } GenericBlockCipher;
+ *
+ * The MAC is generated as described in Section 6.2.3.1.
+ *
+ * IV:
+ *   The Initialization Vector (IV) SHOULD be chosen at random, and MUST be
+ *   unpredictable. Note that in versions of TLS prior to 1.1, there was no
+ *   IV field, and the last ciphertext block of the previous record (the "CBC
+ *   residue") was used as the IV. This was changed to prevent the attacks
+ *   described in [CBCATT]. For block ciphers, the IV length is of length
+ *   SecurityParameters.record_iv_length, which is equal to the
+ *   SecurityParameters.block_size.
+ *
+ * padding:
+ *   Padding that is added to force the length of the plaintext to be an
+ *   integral multiple of the block cipher's block length. The padding MAY be
+ *   any length up to 255 bytes, as long as it results in the
+ *   TLSCiphertext.length being an integral multiple of the block length.
+ *   Lengths longer than necessary might be desirable to frustrate attacks on
+ *   a protocol that are based on analysis of the lengths of exchanged
+ *   messages. Each uint8 in the padding data vector MUST be filled with the
+ *   padding length value. The receiver MUST check this padding and MUST use
+ *   the bad_record_mac alert to indicate padding errors.
+ *
+ * padding_length:
+ *   The padding length MUST be such that the total size of the
+ *   GenericBlockCipher structure is a multiple of the cipher's block length.
+ *   Legal values range from zero to 255, inclusive. This length specifies the
+ *   length of the padding field exclusive of the padding_length field itself.
+ *
+ * The encrypted data length (TLSCiphertext.length) is one more than the sum of
+ * SecurityParameters.block_length, TLSCompressed.length,
+ * SecurityParameters.mac_length, and padding_length.
+ *
+ * Example: If the block length is 8 bytes, the content length
+ * (TLSCompressed.length) is 61 bytes, and the MAC length is 20 bytes, then the
+ * length before padding is 82 bytes (this does not include the IV. Thus, the
+ * padding length modulo 8 must be equal to 6 in order to make the total length
+ * an even multiple of 8 bytes (the block length). The padding length can be
+ * 6, 14, 22, and so on, through 254. If the padding length were the minimum
+ * necessary, 6, the padding would be 6 bytes, each containing the value 6.
+ * Thus, the last 8 octets of the GenericBlockCipher before block encryption
+ * would be xx 06 06 06 06 06 06 06, where xx is the last octet of the MAC.
+ *
+ * Note: With block ciphers in CBC mode (Cipher Block Chaining), it is critical
+ * that the entire plaintext of the record be known before any ciphertext is
+ * transmitted. Otherwise, it is possible for the attacker to mount the attack
+ * described in [CBCATT].
+ *
+ * Implementation note: Canvel et al. [CBCTIME] have demonstrated a timing
+ * attack on CBC padding based on the time required to compute the MAC. In
+ * order to defend against this attack, implementations MUST ensure that
+ * record processing time is essentially the same whether or not the padding
+ * is correct. In general, the best way to do this is to compute the MAC even
+ * if the padding is incorrect, and only then reject the packet. For instance,
+ * if the pad appears to be incorrect, the implementation might assume a
+ * zero-length pad and then compute the MAC. This leaves a small timing
+ * channel, since MAC performance depends, to some extent, on the size of the
+ * data fragment, but it is not believed to be large enough to be exploitable,
+ * due to the large block size of existing MACs and the small size of the
+ * timing signal.

+ * The transistional state tables for receiving TLS records. It maps the

+ *
+ * For instance, if the current state is SHE, then the TLS engine is expecting
+ * a ServerHello record. Once a record is received, the handler function is
+ * looked up using the state SHE and the record's content type.
+ *
+ * The resulting function will either be an error handler or a record handler.
+ * The function will take whatever action is appropriate and update the state
+ * for the next record.
+ *
+ * The states are all based on possible server record types. Note that the
+ * client will never specifically expect to receive a HelloRequest or an alert
+ * from the server so there is no state that reflects this. These messages may
+ * occur at any time.
+ *
+ * There are two tables for mapping states because there is a second tier of
+ * types for handshake messages. Once a record with a content type of handshake
+ * is received, the handshake record handler will look up the handshake type in
+ * the secondary map to get its appropriate handler.

+ *   opaque                 server_random[32];
+ * } SecurityParameters;
+ *
+ * Note that this definition is from TLS 1.2. In TLS 1.0 some of these
+ * parameters are ignored because, for instance, the PRFAlgorithm is a
+ * builtin-fixed algorithm combining iterations of MD5 and SHA-1 in TLS 1.0.
+ *
+ * The Record Protocol requires an algorithm to generate keys required by the
+ * current connection state.
+ *
+ * The master secret is expanded into a sequence of secure bytes, which is then
+ * split to a client write MAC key, a server write MAC key, a client write
+ * encryption key, and a server write encryption key. In TLS 1.0 a client write
+ * IV and server write IV are also generated. Each of these is generated from
+ * the byte sequence in that order. Unused values are empty. In TLS 1.2, some
+ * AEAD ciphers may additionally require a client write IV and a server write
+ * IV (see Section 6.2.3.3).
+ *
+ * When keys, MAC keys, and IVs are generated, the master secret is used as an
+ * entropy source.
+ *
+ * To generate the key material, compute:
+ *
+ * master_secret = PRF(pre_master_secret, "master secret",
+ *                     ClientHello.random + ServerHello.random)
+ *
+ * key_block = PRF(SecurityParameters.master_secret,
+ *                 "key expansion",
+ *                 SecurityParameters.server_random +
+ *                 SecurityParameters.client_random);
+ *
+ * until enough output has been generated. Then, the key_block is
+ * partitioned as follows:
+ *
+ * client_write_MAC_key[SecurityParameters.mac_key_length]
+ * server_write_MAC_key[SecurityParameters.mac_key_length]
+ * client_write_key[SecurityParameters.enc_key_length]
+ * server_write_key[SecurityParameters.enc_key_length]
+ * client_write_IV[SecurityParameters.fixed_iv_length]
+ * server_write_IV[SecurityParameters.fixed_iv_length]
+ *
+ * In TLS 1.2, the client_write_IV and server_write_IV are only generated for
+ * implicit nonce techniques as described in Section 3.2.1 of [AEAD]. This
+ * implementation uses TLS 1.0 so IVs are generated.
+ *
+ * Implementation note: The currently defined cipher suite which requires the
+ * most material is AES_256_CBC_SHA256. It requires 2 x 32 byte keys and 2 x 32
+ * byte MAC keys, for a total 128 bytes of key material. In TLS 1.0 it also
+ * requires 2 x 16 byte IVs, so it actually takes 160 bytes of key material.

+ * @param sp the security parameters to use.

+ *
+ * Meaning of this message:
+ *   If RSA is being used for key agreement and authentication, the client
+ *   generates a 48-byte premaster secret, encrypts it using the public key

+ * Creates a new TLS connection. This does not make any assumptions about the

+ * is a TCP/IP connection or establish one. A TLS connection is totally
+ * abstracted away from the layer is runs on top of, it merely establishes a
+ * secure channel between a client" and a "server".
+ *
+ * A TLS connection contains 4 connection states: pending read and write, and
+ * current read and write.
+ *
+ * At initialization, the current read and write states will be null. Only once
+ * the security parameters have been set and the keys have been generated can
+ * the pending states be converted into current states. Current states will be
+ * updated for each record processed.
+ *
+ * A custom certificate verify callback may be provided to check information
+ * like the common name on the server's certificate. It will be called for
+ * every certificate in the chain. It has the following signature:
+ *
+ * variable func(c, certs, index, preVerify)
+ * Where:
+ * c         The TLS connection
+ * verified  Set to true if certificate was verified, otherwise the alert
+ *           tls.Alert.Description for why the certificate failed.
+ * depth     The current index in the chain, where 0 is the server's cert.
+ * certs     The certificate chain, *NOTE* if the server was anonymous then
+ *           the chain will be empty.
+ *
+ * The function returns true on success and on failure either the appropriate
+ * tls.Alert.Description or an object with 'alert' set to the appropriate
+ * tls.Alert.Description and 'message' set to a custom error message. If true
+ * is not returned then the connection will abort using, in order of
+ * availability, first the returned alert description, second the preVerify
+ * alert description, and lastly the default 'bad_certificate'.
+ *
+ * There are three callbacks that can be used to make use of client-side
+ * certificates where each takes the TLS connection as the first parameter:
+ *
+ * getCertificate(conn, hint)
+ *   The second parameter is a hint as to which certificate should be
+ *   returned. If the connection entity is a client, then the hint will be
+ *   the CertificateRequest message from the server that is part of the
+ *   TLS protocol. If the connection entity is a server, then it will be
+ *   the servername list provided via an SNI extension the ClientHello, if
+ *   one was provided (empty array if not). The hint can be examined to
+ *   determine which certificate to use (advanced). Most implementations
+ *   will just return a certificate. The return value must be a
+ *   PEM-formatted certificate or an array of PEM-formatted certificates
+ *   that constitute a certificate chain, with the first in the array/chain
+ *   being the client's certificate.
+ * getPrivateKey(conn, certificate)
+ *   The second parameter is an forge.pki X.509 certificate object that
+ *   is associated with the requested private key. The return value must
+ *   be a PEM-formatted private key.
+ * getSignature(conn, bytes, callback)
+ *   This callback can be used instead of getPrivateKey if the private key
+ *   is not directly accessible in javascript or should not be. For
+ *   instance, a secure external web service could provide the signature
+ *   in exchange for appropriate credentials. The second parameter is a
+ *   string of bytes to be signed that are part of the TLS protocol. These
+ *   bytes are used to verify that the private key for the previously
+ *   provided client-side certificate is accessible to the client. The
+ *   callback is a function that takes 2 parameters, the TLS connection
+ *   and the RSA encrypted (signed) bytes as a string. This callback must
+ *   be called once the signature is ready.
+ *
+ * @param options the options for this connection:
+ *   server: true if the connection is server-side, false for client.
+ *   sessionId: a session ID to reuse, null for a new connection.
+ *   caStore: an array of certificates to trust.
+ *   sessionCache: a session cache to use.
+ *   cipherSuites: an optional array of cipher suites to use,
+ *     see tls.CipherSuites.
+ *   connected: function(conn) called when the first handshake completes.
+ *   virtualHost: the virtual server name to use in a TLS SNI extension.
+ *   verifyClient: true to require a client certificate in server mode,
+ *     'optional' to request one, false not to (default: false).
+ *   verify: a handler used to custom verify certificates in the chain.
+ *   getCertificate: an optional callback used to get a certificate or
+ *     a chain of certificates (as an array).
+ *   getPrivateKey: an optional callback used to get a private key.
+ *   getSignature: an optional callback used to get a signature.
+ *   tlsDataReady: function(conn) called when TLS protocol data has been
+ *     prepared and is ready to be used (typically sent over a socket
+ *     connection to its destination), read from conn.tlsData buffer.
+ *   dataReady: function(conn) called when application data has

-## Multitransport
+### Multitransport
 
 libp2p is designed to support multiple transports at the same time. While peers are identified by their ID (which are generated from their public keys), the addresses of each pair may vary, depending the device where they are being run or the network in which they are accessible through.
 
 In order for a transport to be supported, it has to follow the [interface-transport](https://github.com/diasdavid/interface-transport) spec.
 
-## Connection upgrades

 Each connection in libp2p follows the [interface-connection](https://github.com/diasdavid/interface-connection) spec. This design decision enables libp2p to have upgradable transports.

 We also want to enable flexibility when it comes to upgrading a connection, for example, we might that all dialed transports pass through the encrypted channel upgrade, but not the congestion flow, specially when a transport might have already some underlying properties (UDP vs TCP vs WebRTC vs every other transport protocol)

 In addition to this, we also share the 'observed addresses' by the other peer, which is extremely useful information for different kinds of network topologies.
 
-## Notes
+### Notes
 
 To avoid the confusion between connection, stream, transport, and other names that represent an abstraction of data flow between two points, we use terms as:
 
 - connection - something that implements the transversal expectations of a stream between two peers, including the benefits of using a stream plus having a way to do half duplex, full duplex
 - transport - something that as a dial/listen interface and return objs that implement a connection interface

 > libp2p swarm implementation in JavaScript.
 
 libp2p-swarm is a connection abstraction that is able to leverage several transports and connection upgrades, such as congestion control, channel encryption, the multiplexing of several streams in one connection, and more. It does this by bringing protocol multiplexing to the application level (instead of the traditional Port level) using multicodec and multistream.
 
-libp2p-swarm is used by [libp2p](https://github.com/diasdavid/js-libp2p) but it can be also used as a standalone module.

- * See NIST SP-800-38D 6.3 (Algorithm 1). This function performs Galois

- *
- * x^128 + x^7 + x^2 + x + 1
- *
- * Which is represented in little-endian binary form as: 11100001 (0xe1). When
- * the value of a coefficient is 1, a bit is set. The value R, is the
- * concatenation of this value and 120 zero bits, yielding a 128-bit value
- * which matches the block size.
- *
- * This function will multiply two elements (vectors of bytes), X and Y, in
- * the field GF(2^128). The result is initialized to zero. For each bit of
- * X (out of 128), x_i, if x_i is set, then the result is multiplied (XOR'd)
- * by the current value of Y. For each bit, the value of Y will be raised by
- * a power of x (multiplied by the polynomial x). This can be achieved by
- * shifting Y once to the right. If the current value of Y, prior to being
- * multiplied by x, has 0 as its LSB, then it is a 127th degree polynomial.
- * Otherwise, we must divide by R after shifting to find the remainder.

-/**
- * Performs initialization, ie: precomputes tables to optimize for speed.
- *
- * One way to understand how AES works is to imagine that 'addition' and
- * 'multiplication' are interfaces that require certain mathematical
- * properties to hold true (ie: they are associative) but they might have
- * different implementations and produce different kinds of results ...
- * provided that their mathematical properties remain true. AES defines
- * its own methods of addition and multiplication but keeps some important
- * properties the same, ie: associativity and distributivity. The
- * explanation below tries to shed some light on how AES defines addition
- * and multiplication of bytes and 32-bit words in order to perform its
- * encryption and decryption algorithms.
- *
- * The basics:
- *
- * The AES algorithm views bytes as binary representations of polynomials
- * that have either 1 or 0 as the coefficients. It defines the addition
- * or subtraction of two bytes as the XOR operation. It also defines the
- * multiplication of two bytes as a finite field referred to as GF(2^8)
- * (Note: 'GF' means "Galois Field" which is a field that contains a finite
- * number of elements so GF(2^8) has 256 elements).
- *
- * This means that any two bytes can be represented as binary polynomials;
- * when they multiplied together and modularly reduced by an irreducible
- * polynomial of the 8th degree, the results are the field GF(2^8). The
- * specific irreducible polynomial that AES uses in hexadecimal is 0x11b.
- * This multiplication is associative with 0x01 as the identity:
- *
- * (b * 0x01 = GF(b, 0x01) = b).
- *
- * The operation GF(b, 0x02) can be performed at the byte level by left
- * shifting b once and then XOR'ing it (to perform the modular reduction)
- * with 0x11b if b is >= 128. Repeated application of the multiplication
- * of 0x02 can be used to implement the multiplication of any two bytes.
- *
- * For instance, multiplying 0x57 and 0x13, denoted as GF(0x57, 0x13), can
- * be performed by factoring 0x13 into 0x01, 0x02, and 0x10. Then these
- * factors can each be multiplied by 0x57 and then added together. To do
- * the multiplication, values for 0x57 multiplied by each of these 3 factors
- * can be precomputed and stored in a table. To add them, the values from
- * the table are XOR'd together.
- *
- * AES also defines addition and multiplication of words, that is 4-byte
- * numbers represented as polynomials of 3 degrees where the coefficients
- * are the values of the bytes.
- *
- * The word [a0, a1, a2, a3] is a polynomial a3x^3 + a2x^2 + a1x + a0.
- *
- * Addition is performed by XOR'ing like powers of x. Multiplication
- * is performed in two steps, the first is an algebriac expansion as
- * you would do normally (where addition is XOR). But the result is
- * a polynomial larger than 3 degrees and thus it cannot fit in a word. So
- * next the result is modularly reduced by an AES-specific polynomial of
- * degree 4 which will always produce a polynomial of less than 4 degrees
- * such that it will fit in a word. In AES, this polynomial is x^4 + 1.
- *
- * The modular product of two polynomials 'a' and 'b' is thus:
- *
- * d(x) = d3x^3 + d2x^2 + d1x + d0
- * with
- * d0 = GF(a0, b0) ^ GF(a3, b1) ^ GF(a2, b2) ^ GF(a1, b3)
- * d1 = GF(a1, b0) ^ GF(a0, b1) ^ GF(a3, b2) ^ GF(a2, b3)
- * d2 = GF(a2, b0) ^ GF(a1, b1) ^ GF(a0, b2) ^ GF(a3, b3)
- * d3 = GF(a3, b0) ^ GF(a2, b1) ^ GF(a1, b2) ^ GF(a0, b3)
- *
- * As a matrix:
- *
- * [d0] = [a0 a3 a2 a1][b0]
- * [d1]   [a1 a0 a3 a2][b1]
- * [d2]   [a2 a1 a0 a3][b2]
- * [d3]   [a3 a2 a1 a0][b3]
- *
- * Special polynomials defined by AES (0x02 == {02}):
- * a(x)    = {03}x^3 + {01}x^2 + {01}x + {02}
- * a^-1(x) = {0b}x^3 + {0d}x^2 + {09}x + {0e}.
- *
- * These polynomials are used in the MixColumns() and InverseMixColumns()
- * operations, respectively, to cause each element in the state to affect
- * the output (referred to as diffusing).
- *
- * RotWord() uses: a0 = a1 = a2 = {00} and a3 = {01}, which is the
- * polynomial x3.
- *
- * The ShiftRows() method modifies the last 3 rows in the state (where
- * the state is 4 words with 4 bytes per word) by shifting bytes cyclically.
- * The 1st byte in the second row is moved to the end of the row. The 1st
- * and 2nd bytes in the third row are moved to the end of the row. The 1st,
- * 2nd, and 3rd bytes are moved in the fourth row.
- *
- * More details on how AES arithmetic works:
- *
- * In the polynomial representation of binary numbers, XOR performs addition
- * and subtraction and multiplication in GF(2^8) denoted as GF(a, b)
- * corresponds with the multiplication of polynomials modulo an irreducible
- * polynomial of degree 8. In other words, for AES, GF(a, b) will multiply
- * polynomial 'a' with polynomial 'b' and then do a modular reduction by
- * an AES-specific irreducible polynomial of degree 8.
- *
- * A polynomial is irreducible if its only divisors are one and itself. For
- * the AES algorithm, this irreducible polynomial is:
- *
- * m(x) = x^8 + x^4 + x^3 + x + 1,
- *
- * or {01}{1b} in hexadecimal notation, where each coefficient is a bit:
- * 100011011 = 283 = 0x11b.
- *
- * For example, GF(0x57, 0x83) = 0xc1 because
- *
- * 0x57 = 87  = 01010111 = x^6 + x^4 + x^2 + x + 1
- * 0x85 = 131 = 10000101 = x^7 + x + 1
- *
- * (x^6 + x^4 + x^2 + x + 1) * (x^7 + x + 1)
- * =  x^13 + x^11 + x^9 + x^8 + x^7 +
- *    x^7 + x^5 + x^3 + x^2 + x +
- *    x^6 + x^4 + x^2 + x + 1
- * =  x^13 + x^11 + x^9 + x^8 + x^6 + x^5 + x^4 + x^3 + 1 = y
- *    y modulo (x^8 + x^4 + x^3 + x + 1)
- * =  x^7 + x^6 + 1.
- *
- * The modular reduction by m(x) guarantees the result will be a binary
- * polynomial of less than degree 8, so that it can fit in a byte.
- *
- * The operation to multiply a binary polynomial b with x (the polynomial
- * x in binary representation is 00000010) is:
- *
- * b_7x^8 + b_6x^7 + b_5x^6 + b_4x^5 + b_3x^4 + b_2x^3 + b_1x^2 + b_0x^1
- *
- * To get GF(b, x) we must reduce that by m(x). If b_7 is 0 (that is the
- * most significant bit is 0 in b) then the result is already reduced. If
- * it is 1, then we can reduce it by subtracting m(x) via an XOR.
- *
- * It follows that multiplication by x (00000010 or 0x02) can be implemented
- * by performing a left shift followed by a conditional bitwise XOR with
- * 0x1b. This operation on bytes is denoted by xtime(). Multiplication by
- * higher powers of x can be implemented by repeated application of xtime().
- *
- * By adding intermediate results, multiplication by any constant can be
- * implemented. For instance:
- *
- * GF(0x57, 0x13) = 0xfe because:
- *
- * xtime(b) = (b & 128) ? (b << 1 ^ 0x11b) : (b << 1)
- *
- * Note: We XOR with 0x11b instead of 0x1b because in javascript our
- * datatype for b can be larger than 1 byte, so a left shift will not
- * automatically eliminate bits that overflow a byte ... by XOR'ing the
- * overflow bit with 1 (the extra one from 0x11b) we zero it out.
- *
- * GF(0x57, 0x02) = xtime(0x57) = 0xae
- * GF(0x57, 0x04) = xtime(0xae) = 0x47
- * GF(0x57, 0x08) = xtime(0x47) = 0x8e
- * GF(0x57, 0x10) = xtime(0x8e) = 0x07
- *
- * GF(0x57, 0x13) = GF(0x57, (0x01 ^ 0x02 ^ 0x10))
- *
- * And by the distributive property (since XOR is addition and GF() is
- * multiplication):
- *
- * = GF(0x57, 0x01) ^ GF(0x57, 0x02) ^ GF(0x57, 0x10)
- * = 0x57 ^ 0xae ^ 0x07
- * = 0xfe.

-
-      It is possible to traverse every possible value in a Galois field
-      using what is referred to as a 'generator'. There are many
-      generators (128 out of 256): 3,5,6,9,11,82 to name a few. To fully
-      traverse GF we iterate 255 times, multiplying by our generator
-      each time.
-
-      On each iteration we can determine the multiplicative inverse for
-      the current element.
-
-      Suppose there is an element in GF 'e'. For a given generator 'g',
-      e = g^x. The multiplicative inverse of e is g^(255 - x). It turns
-      out that if use the inverse of a generator as another generator
-      it will produce all of the corresponding multiplicative inverses
-      at the same time. For this reason, we choose 5 as our inverse
-      generator because it only requires 2 multiplies and 1 add and its
-      inverse, 82, requires relatively few operations as well.
-
-      In order to apply the affine transformation, the multiplicative
-      inverse 'ei' of 'e' can be repeatedly XOR'd (4 times) with a
-      bit-cycling of 'ei'. To do this 'ei' is first stored in 's' and
-      'x'. Then 's' is left shifted and the high bit of 's' is made the
-      low bit. The resulting value is stored in 's'. Then 'x' is XOR'd
-      with 's' and stored in 'x'. On each subsequent iteration the same
-      operation is performed. When 4 iterations are complete, 'x' is
-      XOR'd with 'c' (0x63) and the transformed value is stored in 'x'.
-      For example:
-
-      s = 01000001
-      x = 01000001
-
-      iteration 1: s = 10000010, x ^= s
-      iteration 2: s = 00000101, x ^= s
-      iteration 3: s = 00001010, x ^= s
-      iteration 4: s = 00010100, x ^= s
-      x ^= 0x63
-
-      This can be done with a loop where s = (s << 1) | (s >> 7). However,
-      it can also be done by using a single 16-bit (in this case 32-bit)
-      number 'sx'. Since XOR is an associative operation, we can set 'sx'
-      to 'ei' and then XOR it with 'sx' left-shifted 1,2,3, and 4 times.
-      The most significant bits will flow into the high 8 bit positions
-      and be correctly XOR'd with one another. All that remains will be
-      to cycle the high 8 bits by XOR'ing them all with the lower 8 bits
-      afterwards.
-
-      At the same time we're populating sbox and isbox we can precompute
-      the multiplication we'll need to do to do MixColumns() later.
-    */
-
-    // apply affine transformation
-    sx = ei ^ (ei << 1) ^ (ei << 2) ^ (ei << 3) ^ (ei << 4);
-    sx = (sx >> 8) ^ (sx & 255) ^ 0x63;
-

-
-    /* Mixing columns is done using matrix multiplication. The columns
-      that are to be mixed are each a single word in the current state.
-      The state has Nb columns (4 columns). Therefore each column is a
-      4 byte word. So to mix the columns in a single column 'c' where
-      its rows are r0, r1, r2, and r3, we use the following matrix
-      multiplication:
-
-      [2 3 1 1]*[r0,c]=[r'0,c]
-      [1 2 3 1] [r1,c] [r'1,c]
-      [1 1 2 3] [r2,c] [r'2,c]
-      [3 1 1 2] [r3,c] [r'3,c]
-
-      r0, r1, r2, and r3 are each 1 byte of one of the words in the
-      state (a column). To do matrix multiplication for each mixed
-      column c' we multiply the corresponding row from the left matrix
-      with the corresponding column from the right matrix. In total, we
-      get 4 equations:
-
-      r0,c' = 2*r0,c + 3*r1,c + 1*r2,c + 1*r3,c
-      r1,c' = 1*r0,c + 2*r1,c + 3*r2,c + 1*r3,c
-      r2,c' = 1*r0,c + 1*r1,c + 2*r2,c + 3*r3,c
-      r3,c' = 3*r0,c + 1*r1,c + 1*r2,c + 2*r3,c
-
-      As usual, the multiplication is as previously defined and the
-      addition is XOR. In order to optimize mixing columns we can store
-      the multiplication results in tables. If you think of the whole
-      column as a word (it might help to visualize by mentally rotating
-      the equations above by counterclockwise 90 degrees) then you can
-      see that it would be useful to map the multiplications performed on
-      each byte (r0, r1, r2, r3) onto a word as well. For instance, we
-      could map 2*r0,1*r0,1*r0,3*r0 onto a word by storing 2*r0 in the
-      highest 8 bits and 3*r0 in the lowest 8 bits (with the other two
-      respectively in the middle). This means that a table can be
-      constructed that uses r0 as an index to the word. We can do the
-      same with r1, r2, and r3, creating a total of 4 tables.
-
-      To construct a full c', we can just look up each byte of c in
-      their respective tables and XOR the results together.
-
-      Also, to build each table we only have to calculate the word
-      for 2,1,1,3 for every byte ... which we can do on each iteration
-      of this loop since we will iterate over every byte. After we have
-      calculated 2,1,1,3 we can get the results for the other tables
-      by cycling the byte at the end to the beginning. For instance
-      we can take the result of table 2,1,1,3 and produce table 3,2,1,1
-      by moving the right most byte to the left most position just like
-      how you can imagine the 3 moved out of 2,1,1,3 and to the front
-      to produce 3,2,1,1.
-
-      There is another optimization in that the same multiples of
-      the current element we need in order to advance our generator
-      to the next iteration can be reused in performing the 2,1,1,3
-      calculation. We also calculate the inverse mix column tables,
-      with e,9,d,b being the inverse of 2,1,1,3.
-
-      When we're done, and we need to actually mix columns, the first
-      byte of each state word should be put through mix[0] (2,1,1,3),
-      the second through mix[1] (3,2,1,1) and so forth. Then they should
-      be XOR'd together to produce the fully mixed column.

-   /* When we are updating a cipher block we always use the code path for
-     encryption whether we are decrypting or not (to shorten code and
-     simplify the generation of look up tables). However, because there
-     are differences in the decryption algorithm, other than just swapping
-     in different look up tables, we must transform our key schedule to
-     account for these changes:
-
-     1. The decryption algorithm gets its key rounds in reverse order.
-     2. The decryption algorithm adds the round key before mixing columns
-       instead of afterwards.
-
-     We don't need to modify our key schedule to handle the first case,
-     we can just traverse the key schedule in reverse order when decrypting.
-
-     The second case requires a little work.
-
-     The tables we built for performing rounds will take an input and then
-     perform SubBytes() and MixColumns() or, for the decrypt version,
-     InvSubBytes() and InvMixColumns(). But the decrypt algorithm requires
-     us to AddRoundKey() before InvMixColumns(). This means we'll need to
-     apply some transformations to the round key to inverse-mix its columns
-     so they'll be correct for moving AddRoundKey() to after the state has
-     had its columns inverse-mixed.
-
-     To inverse-mix the columns of the state when we're decrypting we use a
-     lookup table that will apply InvSubBytes() and InvMixColumns() at the
-     same time. However, the round key's bytes are not inverse-substituted
-     in the decryption algorithm. To get around this problem, we can first
-     substitute the bytes in the round key so that when we apply the
-     transformation via the InvSubBytes()+InvMixColumns() table, it will
-     undo our substitution leaving us with the original value that we
-     want -- and then inverse-mix that value.
-
-     This change will correctly alter our key schedule so that we can XOR
-     each round key with our already transformed decryption state. This
-     allows us to use the same code path as the encryption algorithm.
-
-     We make one more change to the decryption key. Since the decryption
-     algorithm runs in reverse from the encryption algorithm, we reverse
-     the order of the round keys to avoid having to iterate over the key
-     schedule backwards when running the encryption algorithm later in
-     decryption mode. In addition to reversing the order of the round keys,
-     we also swap each round key's 2nd and 4th rows. See the comments
-     section where rounds are performed for more details about why this is
-     done. These changes are done inline with the other substitution
-     described above.

-      array 'input' has one column as a word at each index). In order to
-      mix a column, we perform these transformations on each row in c,
-      which is 1 byte in each word. The new column for c0 is c'0:
-
-               m0      m1      m2      m3
-      r0,c'0 = 2*r0,c0 + 3*r1,c0 + 1*r2,c0 + 1*r3,c0
-      r1,c'0 = 1*r0,c0 + 2*r1,c0 + 3*r2,c0 + 1*r3,c0

-      r3,c'0 = 3*r0,c0 + 1*r1,c0 + 1*r2,c0 + 2*r3,c0
-
-      So using mix tables where c0 is a word with r0 being its upper
-      8 bits and r3 being its lower 8 bits:
-
-      m0[c0 >> 24] will yield this word: [2*r0,1*r0,1*r0,3*r0]
-      ...
-      m3[c0 & 255] will yield this word: [1*r3,1*r3,3*r3,2*r3]
-
-      Therefore to mix the columns in each word in the state we
-      do the following (& 255 omitted for brevity):
-      c'0,r0 = m0[c0 >> 24] ^ m1[c1 >> 16] ^ m2[c2 >> 8] ^ m3[c3]
-      c'0,r1 = m0[c0 >> 24] ^ m1[c1 >> 16] ^ m2[c2 >> 8] ^ m3[c3]
-      c'0,r2 = m0[c0 >> 24] ^ m1[c1 >> 16] ^ m2[c2 >> 8] ^ m3[c3]
-      c'0,r3 = m0[c0 >> 24] ^ m1[c1 >> 16] ^ m2[c2 >> 8] ^ m3[c3]
-
-      However, before mixing, the algorithm requires us to perform
-      ShiftRows(). The ShiftRows() transformation cyclically shifts the
-      last 3 rows of the state over different offsets. The first row
-      (r = 0) is not shifted.
-
-      s'_r,c = s_r,(c + shift(r, Nb) mod Nb
-      for 0 < r < 4 and 0 <= c < Nb and
-      shift(1, 4) = 1
-      shift(2, 4) = 2
-      shift(3, 4) = 3.
-
-      This causes the first byte in r = 1 to be moved to the end of
-      the row, the first 2 bytes in r = 2 to be moved to the end of
-      the row, the first 3 bytes in r = 3 to be moved to the end of
-      the row:
-
-      r1: [c0 c1 c2 c3] => [c1 c2 c3 c0]
-      r2: [c0 c1 c2 c3]    [c2 c3 c0 c1]
-      r3: [c0 c1 c2 c3]    [c3 c0 c1 c2]
-
-      We can make these substitutions inline with our column mixing to
-      generate an updated set of equations to produce each word in the
-      state (note the columns have changed positions):
-
-      c0 c1 c2 c3 => c0 c1 c2 c3
-      c0 c1 c2 c3    c1 c2 c3 c0  (cycled 1 byte)
-      c0 c1 c2 c3    c2 c3 c0 c1  (cycled 2 bytes)
-      c0 c1 c2 c3    c3 c0 c1 c2  (cycled 3 bytes)
-
-      Therefore:
-
-      c'0 = 2*r0,c0 + 3*r1,c1 + 1*r2,c2 + 1*r3,c3
-      c'0 = 1*r0,c0 + 2*r1,c1 + 3*r2,c2 + 1*r3,c3
-      c'0 = 1*r0,c0 + 1*r1,c1 + 2*r2,c2 + 3*r3,c3
-      c'0 = 3*r0,c0 + 1*r1,c1 + 1*r2,c2 + 2*r3,c3
-
-      c'1 = 2*r0,c1 + 3*r1,c2 + 1*r2,c3 + 1*r3,c0
-      c'1 = 1*r0,c1 + 2*r1,c2 + 3*r2,c3 + 1*r3,c0
-      c'1 = 1*r0,c1 + 1*r1,c2 + 2*r2,c3 + 3*r3,c0
-      c'1 = 3*r0,c1 + 1*r1,c2 + 1*r2,c3 + 2*r3,c0
-
-      ... and so forth for c'2 and c'3. The important distinction is
-      that the columns are cycling, with c0 being used with the m0
-      map when calculating c0, but c1 being used with the m0 map when
-      calculating c1 ... and so forth.
-
-      When performing the inverse we transform the mirror image and
-      skip the bottom row, instead of the top one, and move upwards:
-
-      c3 c2 c1 c0 => c0 c3 c2 c1  (cycled 3 bytes) *same as encryption
-      c3 c2 c1 c0    c1 c0 c3 c2  (cycled 2 bytes)
-      c3 c2 c1 c0    c2 c1 c0 c3  (cycled 1 byte)  *same as encryption
-      c3 c2 c1 c0    c3 c2 c1 c0
-
-      If you compare the resulting matrices for ShiftRows()+MixColumns()
-      and for InvShiftRows()+InvMixColumns() the 2nd and 4th columns are
-      different (in encrypt mode vs. decrypt mode). So in order to use
-      the same code to handle both encryption and decryption, we will
-      need to do some mapping.
-
-      If in encryption mode we let a=c0, b=c1, c=c2, d=c3, and r<N> be
-      a row number in the state, then the resulting matrix in encryption
-      mode for applying the above transformations would be:
-
-      r1: a b c d
-      r2: b c d a
-      r3: c d a b
-      r4: d a b c
-
-      If we did the same in decryption mode we would get:
-
-      r1: a d c b
-      r2: b a d c
-      r3: c b a d
-      r4: d c b a
-
-      If instead we swap d and b (set b=c3 and d=c1), then we get:
-
-      r1: a b c d
-      r2: d a b c
-      r3: c d a b
-      r4: b c d a
-
-      Now the 1st and 3rd rows are the same as the encryption matrix. All
-      we need to do then to make the mapping exactly the same is to swap
-      the 2nd and 4th rows when in decryption mode. To do this without
-      having to do it on each iteration, we swapped the 2nd and 4th rows
-      in the decryption key schedule. We also have to do the swap above
-      when we first pull in the input and when we set the final output. */

-/**
- * Javascript implementation of Abstract Syntax Notation Number One.
- *
- * @author Dave Longley
- *
- * Copyright (c) 2010-2015 Digital Bazaar, Inc.
- *
- * An API for storing data using the Abstract Syntax Notation Number One
- * format using DER (Distinguished Encoding Rules) encoding. This encoding is
- * commonly used to store data for PKI, i.e. X.509 Certificates, and this
- * implementation exists for that purpose.
- *
- * Abstract Syntax Notation Number One (ASN.1) is used to define the abstract
- * syntax of information without restricting the way the information is encoded
- * for transmission. It provides a standard that allows for open systems
- * communication. ASN.1 defines the syntax of information data and a number of
- * simple data types as well as a notation for describing them and specifying
- * values for them.
- *
- * The RSA algorithm creates public and private keys that are often stored in
- * X.509 or PKCS#X formats -- which use ASN.1 (encoded in DER format). This
- * class provides the most basic functionality required to store and load DSA
- * keys that are encoded according to ASN.1.
- *
- * The most common binary encodings for ASN.1 are BER (Basic Encoding Rules)
- * and DER (Distinguished Encoding Rules). DER is just a subset of BER that
- * has stricter requirements for how data must be encoded.
- *
- * Each ASN.1 structure has a tag (a byte identifying the ASN.1 structure type)
- * and a byte array for the value of this ASN1 structure which may be data or a
- * list of ASN.1 structures.
- *
- * Each ASN.1 structure using BER is (Tag-Length-Value):
- *
- * | byte 0 | bytes X | bytes Y |
- * |--------|---------|----------
- * |  tag   | length  |  value  |
- *
- * ASN.1 allows for tags to be of "High-tag-number form" which allows a tag to
- * be two or more octets, but that is not supported by this class. A tag is
- * only 1 byte. Bits 1-5 give the tag number (ie the data type within a
- * particular 'class'), 6 indicates whether or not the ASN.1 value is
- * constructed from other ASN.1 values, and bits 7 and 8 give the 'class'. If
- * bits 7 and 8 are both zero, the class is UNIVERSAL. If only bit 7 is set,
- * then the class is APPLICATION. If only bit 8 is set, then the class is
- * CONTEXT_SPECIFIC. If both bits 7 and 8 are set, then the class is PRIVATE.
- * The tag numbers for the data types for the class UNIVERSAL are listed below:
- *
- * UNIVERSAL 0 Reserved for use by the encoding rules
- * UNIVERSAL 1 Boolean type
- * UNIVERSAL 2 Integer type
- * UNIVERSAL 3 Bitstring type
- * UNIVERSAL 4 Octetstring type
- * UNIVERSAL 5 Null type
- * UNIVERSAL 6 Object identifier type
- * UNIVERSAL 7 Object descriptor type
- * UNIVERSAL 8 External type and Instance-of type
- * UNIVERSAL 9 Real type
- * UNIVERSAL 10 Enumerated type
- * UNIVERSAL 11 Embedded-pdv type
- * UNIVERSAL 12 UTF8String type
- * UNIVERSAL 13 Relative object identifier type
- * UNIVERSAL 14-15 Reserved for future editions
- * UNIVERSAL 16 Sequence and Sequence-of types
- * UNIVERSAL 17 Set and Set-of types
- * UNIVERSAL 18-22, 25-30 Character string types
- * UNIVERSAL 23-24 Time types
- *
- * The length of an ASN.1 structure is specified after the tag identifier.
- * There is a definite form and an indefinite form. The indefinite form may
- * be used if the encoding is constructed and not all immediately available.
- * The indefinite form is encoded using a length byte with only the 8th bit
- * set. The end of the constructed object is marked using end-of-contents
- * octets (two zero bytes).
- *
- * The definite form looks like this:
- *
- * The length may take up 1 or more bytes, it depends on the length of the
- * value of the ASN.1 structure. DER encoding requires that if the ASN.1
- * structure has a value that has a length greater than 127, more than 1 byte
- * will be used to store its length, otherwise just one byte will be used.
- * This is strict.
- *
- * In the case that the length of the ASN.1 value is less than 127, 1 octet
- * (byte) is used to store the "short form" length. The 8th bit has a value of
- * 0 indicating the length is "short form" and not "long form" and bits 7-1
- * give the length of the data. (The 8th bit is the left-most, most significant
- * bit: also known as big endian or network format).
- *
- * In the case that the length of the ASN.1 value is greater than 127, 2 to
- * 127 octets (bytes) are used to store the "long form" length. The first
- * byte's 8th bit is set to 1 to indicate the length is "long form." Bits 7-1
- * give the number of additional octets. All following octets are in base 256
- * with the most significant digit first (typical big-endian binary unsigned
- * integer storage). So, for instance, if the length of a value was 257, the
- * first byte would be set to:
- *
- * 10000010 = 130 = 0x82.
- *
- * This indicates there are 2 octets (base 256) for the length. The second and
- * third bytes (the octets just mentioned) would store the length in base 256:
- *
- * octet 2: 00000001 = 1 * 256^1 = 256
- * octet 3: 00000001 = 1 * 256^0 = 1
- * total = 257
- *
- * The algorithm for converting a js integer value of 257 to base-256 is:
- *
- * var value = 257;
- * var bytes = [];
- * bytes[0] = (value >>> 8) & 0xFF; // most significant byte first
- * bytes[1] = value & 0xFF;        // least significant byte last
- *
- * On the ASN.1 UNIVERSAL Object Identifier (OID) type:
- *
- * An OID can be written like: "value1.value2.value3...valueN"
- *
- * The DER encoding rules:
- *
- * The first byte has the value 40 * value1 + value2.
- * The following bytes, if any, encode the remaining values. Each value is
- * encoded in base 128, most significant digit first (big endian), with as
- * few digits as possible, and the most significant bit of each byte set
- * to 1 except the last in each value's encoding. For example: Given the
- * OID "1.2.840.113549", its DER encoding is (remember each byte except the
- * last one in each encoding is OR'd with 0x80):
- *
- * byte 1: 40 * 1 + 2 = 42 = 0x2A.
- * bytes 2-3: 128 * 6 + 72 = 840 = 6 72 = 6 72 = 0x0648 = 0x8648
- * bytes 4-6: 16384 * 6 + 128 * 119 + 13 = 6 119 13 = 0x06770D = 0x86F70D
- *
- * The final value is: 0x2A864886F70D.
- * The full OID (including ASN.1 tag and length of 6 bytes) is:
- * 0x06062A864886F70D

-  /* Chinese remainder theorem (CRT) states:
-
-    Suppose n1, n2, ..., nk are positive integers which are pairwise
-    coprime (n1 and n2 have no common factors other than 1). For any
-    integers x1, x2, ..., xk there exists an integer x solving the
-    system of simultaneous congruences (where ~= means modularly
-    congruent so a ~= b mod n means a mod n = b mod n):
-
-    x ~= x1 mod n1
-    x ~= x2 mod n2
-    ...
-    x ~= xk mod nk
-
-    This system of congruences has a single simultaneous solution x
-    between 0 and n - 1. Furthermore, each xk solution and x itself
-    is congruent modulo the product n = n1*n2*...*nk.
-    So x1 mod n = x2 mod n = xk mod n = x mod n.
-
-    The single simultaneous solution x can be solved with the following
-    equation:
-
-    x = sum(xi*ri*si) mod n where ri = n/ni and si = ri^-1 mod ni.
-
-    Where x is less than n, xi = x mod ni.
-
-    For RSA we are only concerned with k = 2. The modulus n = pq, where
-    p and q are coprime. The RSA decryption algorithm is:
-
-    y = x^d mod n
-
-    Given the above:
-
-    x1 = x^d mod p
-    r1 = n/p = q
-    s1 = q^-1 mod p
-    x2 = x^d mod q
-    r2 = n/q = p
-    s2 = p^-1 mod q
-
-    So y = (x1r1s1 + x2r2s2) mod n
-         = ((x^d mod p)q(q^-1 mod p) + (x^d mod q)p(p^-1 mod q)) mod n
-
-    According to Fermat's Little Theorem, if the modulus P is prime,
-    for any integer A not evenly divisible by P, A^(P-1) ~= 1 mod P.
-    Since A is not divisible by P it follows that if:
-    N ~= M mod (P - 1), then A^N mod P = A^M mod P. Therefore:
-
-    A^N mod P = A^(M mod (P - 1)) mod P. (The latter takes less effort
-    to calculate). In order to calculate x^d mod p more quickly the
-    exponent d mod (p - 1) is stored in the RSA private key (the same
-    is done for x^d mod q). These values are referred to as dP and dQ
-    respectively. Therefore we now have:
-
-    y = ((x^dP mod p)q(q^-1 mod p) + (x^dQ mod q)p(p^-1 mod q)) mod n
-
-    Since we'll be reducing x^dP by modulo p (same for q) we can also
-    reduce x by p (and q respectively) before hand. Therefore, let
-
-    xp = ((x mod p)^dP mod p), and
-    xq = ((x mod q)^dQ mod q), yielding:
-
-    y = (xp*q*(q^-1 mod p) + xq*p*(p^-1 mod q)) mod n
-
-    This can be further reduced to a simple algorithm that only
-    requires 1 inverse (the q inverse is used) to be used and stored.
-    The algorithm is called Garner's algorithm. If qInv is the
-    inverse of q, we simply calculate:
-
-    y = (qInv*(xp - xq) mod p) * q + xq
-
-    However, there are two further complications. First, we need to
-    ensure that xp > xq to prevent signed BigIntegers from being used
-    so we add p until this is true (since we will be mod'ing with
-    p anyway). Then, there is a known timing attack on algorithms
-    using the CRT. To mitigate this risk, "cryptographic blinding"
-    should be used. This requires simply generating a random number r
-    between 0 and n-1 and its inverse and multiplying x by r^e before
-    calculating y and then multiplying y by r^-1 afterwards. Note that
-    r must be coprime with n (gcd(r, n) === 1) in order to have an
-    inverse.

-  /* From: RFC3280 - Internet X.509 Public Key Infrastructure Certificate
-    Section 6: Certification Path Validation
-    See inline parentheticals related to this particular implementation.
-
-    The primary goal of path validation is to verify the binding between
-    a subject distinguished name or a subject alternative name and subject
-    public key, as represented in the end entity certificate, based on the
-    public key of the trust anchor. This requires obtaining a sequence of
-    certificates that support that binding. That sequence should be provided
-    in the passed 'chain'. The trust anchor should be in the given CA
-    store. The 'end entity' certificate is the certificate provided by the
-    end point (typically a server) and is the first in the chain.
-
-    To meet this goal, the path validation process verifies, among other
-    things, that a prospective certification path (a sequence of n
-    certificates or a 'chain') satisfies the following conditions:
-
-    (a) for all x in {1, ..., n-1}, the subject of certificate x is
-          the issuer of certificate x+1;
-
-    (b) certificate 1 is issued by the trust anchor;
-
-    (c) certificate n is the certificate to be validated; and
-
-    (d) for all x in {1, ..., n}, the certificate was valid at the
-          time in question.
-
-    Note that here 'n' is index 0 in the chain and 1 is the last certificate
-    in the chain and it must be signed by a certificate in the connection's
-    CA store.
-
-    The path validation process also determines the set of certificate
-    policies that are valid for this path, based on the certificate policies
-    extension, policy mapping extension, policy constraints extension, and
-    inhibit any-policy extension.
-
-    Note: Policy mapping extension not supported (Not Required).
-
-    Note: If the certificate has an unsupported critical extension, then it
-    must be rejected.
-
-    Note: A certificate is self-issued if the DNs that appear in the subject
-    and issuer fields are identical and are not empty.
-
-    The path validation algorithm assumes the following seven inputs are
-    provided to the path processing logic. What this specific implementation
-    will use is provided parenthetically:
-
-    (a) a prospective certification path of length n (the 'chain')
-    (b) the current date/time: ('now').
-    (c) user-initial-policy-set: A set of certificate policy identifiers
-          naming the policies that are acceptable to the certificate user.
-          The user-initial-policy-set contains the special value any-policy
-          if the user is not concerned about certificate policy
-          (Not implemented. Any policy is accepted).
-    (d) trust anchor information, describing a CA that serves as a trust
-          anchor for the certification path. The trust anchor information
-          includes:
-
-      (1)  the trusted issuer name,
-      (2)  the trusted public key algorithm,
-      (3)  the trusted public key, and
-      (4)  optionally, the trusted public key parameters associated
-             with the public key.
-
-      (Trust anchors are provided via certificates in the CA store).
-
-      The trust anchor information may be provided to the path processing
-      procedure in the form of a self-signed certificate. The trusted anchor
-      information is trusted because it was delivered to the path processing
-      procedure by some trustworthy out-of-band procedure. If the trusted
-      public key algorithm requires parameters, then the parameters are
-      provided along with the trusted public key (No parameters used in this
-      implementation).
-
-    (e) initial-policy-mapping-inhibit, which indicates if policy mapping is
-          allowed in the certification path.
-          (Not implemented, no policy checking)
-
-    (f) initial-explicit-policy, which indicates if the path must be valid
-          for at least one of the certificate policies in the user-initial-
-          policy-set.
-          (Not implemented, no policy checking)
-
-    (g) initial-any-policy-inhibit, which indicates whether the
-          anyPolicy OID should be processed if it is included in a
-          certificate.
-          (Not implemented, so any policy is valid provided that it is
-          not marked as critical) */
-
-  /* Basic Path Processing:
-
-    For each certificate in the 'chain', the following is checked:
-
-    1. The certificate validity period includes the current time.
-    2. The certificate was signed by its parent (where the parent is either
-       the next in the chain or from the CA store). Allow processing to
-       continue to the next step if no parent is found but the certificate is
-       in the CA store.
-    3. TODO: The certificate has not been revoked.
-    4. The certificate issuer name matches the parent's subject name.
-    5. TODO: If the certificate is self-issued and not the final certificate
-       in the chain, skip this step, otherwise verify that the subject name
-       is within one of the permitted subtrees of X.500 distinguished names
-       and that each of the alternative names in the subjectAltName extension
-       (critical or non-critical) is within one of the permitted subtrees for
-       that name type.
-    6. TODO: If the certificate is self-issued and not the final certificate
-       in the chain, skip this step, otherwise verify that the subject name
-       is not within one of the excluded subtrees for X.500 distinguished
-       names and none of the subjectAltName extension names are excluded for
-       that name type.
-    7. The other steps in the algorithm for basic path processing involve
-       handling the policy extension which is not presently supported in this
-       implementation. Instead, if a critical policy extension is found, the
-       certificate is rejected as not supported.
-    8. If the certificate is not the first or if its the only certificate in
-       the chain (having no parent from the CA store or is self-signed) and it
-       has a critical key usage extension, verify that the keyCertSign bit is
-       set. If the key usage extension exists, verify that the basic
-       constraints extension exists. If the basic constraints extension exists,
-       verify that the cA flag is set. If pathLenConstraint is set, ensure that
-       the number of certificates that precede in the chain (come earlier
-       in the chain as implemented below), excluding the very first in the
-       chain (typically the end-entity one), isn't greater than the
-       pathLenConstraint. This constraint limits the number of intermediate
-       CAs that may appear below a CA before only end-entity certificates
-       may be issued. */

- *
- * The ASN.1 representation of PKCS#12 is as follows
- * (see ftp://ftp.rsasecurity.com/pub/pkcs/pkcs-12/pkcs-12-tc1.pdf for details)
- *
- * PFX ::= SEQUENCE {
- *   version  INTEGER {v3(3)}(v3,...),
- *   authSafe ContentInfo,
- *   macData  MacData OPTIONAL
- * }
- *
- * MacData ::= SEQUENCE {
- *   mac DigestInfo,
- *   macSalt OCTET STRING,
- *   iterations INTEGER DEFAULT 1
- * }
- * Note: The iterations default is for historical reasons and its use is
- * deprecated. A higher value, like 1024, is recommended.
- *
- * DigestInfo is defined in PKCS#7 as follows:
- *
- * DigestInfo ::= SEQUENCE {
- *   digestAlgorithm DigestAlgorithmIdentifier,
- *   digest Digest
- * }
- *
- * DigestAlgorithmIdentifier ::= AlgorithmIdentifier
- *
- * The AlgorithmIdentifier contains an Object Identifier (OID) and parameters
- * for the algorithm, if any. In the case of SHA1 there is none.
- *
- * AlgorithmIdentifer ::= SEQUENCE {
- *    algorithm OBJECT IDENTIFIER,
- *    parameters ANY DEFINED BY algorithm OPTIONAL
- * }
- *
- * Digest ::= OCTET STRING
- *
- *
- * ContentInfo ::= SEQUENCE {
- *   contentType ContentType,
- *   content     [0] EXPLICIT ANY DEFINED BY contentType OPTIONAL
- * }
- *
- * ContentType ::= OBJECT IDENTIFIER
- *
- * AuthenticatedSafe ::= SEQUENCE OF ContentInfo
- * -- Data if unencrypted
- * -- EncryptedData if password-encrypted
- * -- EnvelopedData if public key-encrypted
- *
- *
- * SafeContents ::= SEQUENCE OF SafeBag
- *
- * SafeBag ::= SEQUENCE {

- *   attrValues SET OF ATTRIBUTE.&Type ({PKCS12AttrSet}{@attrId})
- * } -- This type is compatible with the X.500 type ’Attribute’
- *
- * PKCS12AttrSet ATTRIBUTE ::= {
- *   friendlyName | -- from PKCS #9

-/**
- * A Javascript implementation of Transport Layer Security (TLS).
- *
- * @author Dave Longley
- *
- * Copyright (c) 2009-2014 Digital Bazaar, Inc.
- *
- * The TLS Handshake Protocol involves the following steps:
- *
- * - Exchange hello messages to agree on algorithms, exchange random values,
- * and check for session resumption.
- *
- * - Exchange the necessary cryptographic parameters to allow the client and
- * server to agree on a premaster secret.
- *
- * - Exchange certificates and cryptographic information to allow the client
- * and server to authenticate themselves.
- *
- * - Generate a master secret from the premaster secret and exchanged random
- * values.
- *
- * - Provide security parameters to the record layer.
- *
- * - Allow the client and server to verify that their peer has calculated the
- * same security parameters and that the handshake occurred without tampering
- * by an attacker.
- *
- * Up to 4 different messages may be sent during a key exchange. The server
- * certificate, the server key exchange, the client certificate, and the
- * client key exchange.
- *
- * A typical handshake (from the client's perspective).
- *
- * 1. Client sends ClientHello.
- * 2. Client receives ServerHello.
- * 3. Client receives optional Certificate.
- * 4. Client receives optional ServerKeyExchange.
- * 5. Client receives ServerHelloDone.
- * 6. Client sends optional Certificate.
- * 7. Client sends ClientKeyExchange.
- * 8. Client sends optional CertificateVerify.
- * 9. Client sends ChangeCipherSpec.
- * 10. Client sends Finished.
- * 11. Client receives ChangeCipherSpec.
- * 12. Client receives Finished.
- * 13. Client sends/receives application data.
- *
- * To reuse an existing session:
- *
- * 1. Client sends ClientHello with session ID for reuse.
- * 2. Client receives ServerHello with same session ID if reusing.
- * 3. Client receives ChangeCipherSpec message if reusing.
- * 4. Client receives Finished.
- * 5. Client sends ChangeCipherSpec.
- * 6. Client sends Finished.
- *
- * Note: Client ignores HelloRequest if in the middle of a handshake.
- *
- * Record Layer:
- *
- * The record layer fragments information blocks into TLSPlaintext records
- * carrying data in chunks of 2^14 bytes or less. Client message boundaries are
- * not preserved in the record layer (i.e., multiple client messages of the
- * same ContentType MAY be coalesced into a single TLSPlaintext record, or a
- * single message MAY be fragmented across several records).
- *
- * struct {
- *   uint8 major;
- *   uint8 minor;
- * } ProtocolVersion;
- *
- * struct {
- *   ContentType type;
- *   ProtocolVersion version;
- *   uint16 length;
- *   opaque fragment[TLSPlaintext.length];
- * } TLSPlaintext;
- *
- * type:
- *   The higher-level protocol used to process the enclosed fragment.
- *
- * version:
- *   The version of the protocol being employed. TLS Version 1.2 uses version
- *   {3, 3}. TLS Version 1.0 uses version {3, 1}. Note that a client that
- *   supports multiple versions of TLS may not know what version will be
- *   employed before it receives the ServerHello.
- *
- * length:
- *   The length (in bytes) of the following TLSPlaintext.fragment. The length
- *   MUST NOT exceed 2^14 = 16384 bytes.
- *
- * fragment:
- *   The application data. This data is transparent and treated as an
- *   independent block to be dealt with by the higher-level protocol specified
- *   by the type field.
- *
- * Implementations MUST NOT send zero-length fragments of Handshake, Alert, or
- * ChangeCipherSpec content types. Zero-length fragments of Application data
- * MAY be sent as they are potentially useful as a traffic analysis
- * countermeasure.
- *
- * Note: Data of different TLS record layer content types MAY be interleaved.
- * Application data is generally of lower precedence for transmission than
- * other content types. However, records MUST be delivered to the network in
- * the same order as they are protected by the record layer. Recipients MUST
- * receive and process interleaved application layer traffic during handshakes
- * subsequent to the first one on a connection.
- *
- * struct {
- *   ContentType type;       // same as TLSPlaintext.type
- *   ProtocolVersion version;// same as TLSPlaintext.version
- *   uint16 length;
- *   opaque fragment[TLSCompressed.length];
- * } TLSCompressed;
- *
- * length:
- *   The length (in bytes) of the following TLSCompressed.fragment.
- *   The length MUST NOT exceed 2^14 + 1024.
- *
- * fragment:
- *   The compressed form of TLSPlaintext.fragment.
- *
- * Note: A CompressionMethod.null operation is an identity operation; no fields
- * are altered. In this implementation, since no compression is supported,
- * uncompressed records are always the same as compressed records.
- *
- * Encryption Information:
- *
- * The encryption and MAC functions translate a TLSCompressed structure into a
- * TLSCiphertext. The decryption functions reverse the process. The MAC of the
- * record also includes a sequence number so that missing, extra, or repeated
- * messages are detectable.
- *
- * struct {
- *   ContentType type;
- *   ProtocolVersion version;
- *   uint16 length;
- *   select (SecurityParameters.cipher_type) {
- *     case stream: GenericStreamCipher;
- *     case block:  GenericBlockCipher;
- *     case aead:   GenericAEADCipher;
- *   } fragment;
- * } TLSCiphertext;
- *
- * type:
- *   The type field is identical to TLSCompressed.type.
- *
- * version:
- *   The version field is identical to TLSCompressed.version.
- *
- * length:
- *   The length (in bytes) of the following TLSCiphertext.fragment.
- *   The length MUST NOT exceed 2^14 + 2048.
- *
- * fragment:
- *   The encrypted form of TLSCompressed.fragment, with the MAC.
- *
- * Note: Only CBC Block Ciphers are supported by this implementation.
- *
- * The TLSCompressed.fragment structures are converted to/from block
- * TLSCiphertext.fragment structures.
- *
- * struct {
- *   opaque IV[SecurityParameters.record_iv_length];
- *   block-ciphered struct {
- *     opaque content[TLSCompressed.length];
- *     opaque MAC[SecurityParameters.mac_length];
- *     uint8 padding[GenericBlockCipher.padding_length];
- *     uint8 padding_length;
- *   };
- * } GenericBlockCipher;
- *
- * The MAC is generated as described in Section 6.2.3.1.
- *
- * IV:
- *   The Initialization Vector (IV) SHOULD be chosen at random, and MUST be
- *   unpredictable. Note that in versions of TLS prior to 1.1, there was no
- *   IV field, and the last ciphertext block of the previous record (the "CBC
- *   residue") was used as the IV. This was changed to prevent the attacks
- *   described in [CBCATT]. For block ciphers, the IV length is of length
- *   SecurityParameters.record_iv_length, which is equal to the
- *   SecurityParameters.block_size.
- *
- * padding:
- *   Padding that is added to force the length of the plaintext to be an
- *   integral multiple of the block cipher's block length. The padding MAY be
- *   any length up to 255 bytes, as long as it results in the
- *   TLSCiphertext.length being an integral multiple of the block length.
- *   Lengths longer than necessary might be desirable to frustrate attacks on
- *   a protocol that are based on analysis of the lengths of exchanged
- *   messages. Each uint8 in the padding data vector MUST be filled with the
- *   padding length value. The receiver MUST check this padding and MUST use
- *   the bad_record_mac alert to indicate padding errors.
- *
- * padding_length:
- *   The padding length MUST be such that the total size of the
- *   GenericBlockCipher structure is a multiple of the cipher's block length.
- *   Legal values range from zero to 255, inclusive. This length specifies the
- *   length of the padding field exclusive of the padding_length field itself.
- *
- * The encrypted data length (TLSCiphertext.length) is one more than the sum of
- * SecurityParameters.block_length, TLSCompressed.length,
- * SecurityParameters.mac_length, and padding_length.
- *
- * Example: If the block length is 8 bytes, the content length
- * (TLSCompressed.length) is 61 bytes, and the MAC length is 20 bytes, then the
- * length before padding is 82 bytes (this does not include the IV. Thus, the
- * padding length modulo 8 must be equal to 6 in order to make the total length
- * an even multiple of 8 bytes (the block length). The padding length can be
- * 6, 14, 22, and so on, through 254. If the padding length were the minimum
- * necessary, 6, the padding would be 6 bytes, each containing the value 6.
- * Thus, the last 8 octets of the GenericBlockCipher before block encryption
- * would be xx 06 06 06 06 06 06 06, where xx is the last octet of the MAC.
- *
- * Note: With block ciphers in CBC mode (Cipher Block Chaining), it is critical
- * that the entire plaintext of the record be known before any ciphertext is
- * transmitted. Otherwise, it is possible for the attacker to mount the attack
- * described in [CBCATT].
- *
- * Implementation note: Canvel et al. [CBCTIME] have demonstrated a timing
- * attack on CBC padding based on the time required to compute the MAC. In
- * order to defend against this attack, implementations MUST ensure that
- * record processing time is essentially the same whether or not the padding
- * is correct. In general, the best way to do this is to compute the MAC even
- * if the padding is incorrect, and only then reject the packet. For instance,
- * if the pad appears to be incorrect, the implementation might assume a
- * zero-length pad and then compute the MAC. This leaves a small timing
- * channel, since MAC performance depends, to some extent, on the size of the
- * data fragment, but it is not believed to be large enough to be exploitable,
- * due to the large block size of existing MACs and the small size of the
- * timing signal.

-/**
- * The transistional state tables for receiving TLS records. It maps the
- * current TLS engine state and a received record to a function to handle the
- * record and update the state.
- *
- * For instance, if the current state is SHE, then the TLS engine is expecting
- * a ServerHello record. Once a record is received, the handler function is
- * looked up using the state SHE and the record's content type.
- *
- * The resulting function will either be an error handler or a record handler.
- * The function will take whatever action is appropriate and update the state
- * for the next record.
- *
- * The states are all based on possible server record types. Note that the
- * client will never specifically expect to receive a HelloRequest or an alert
- * from the server so there is no state that reflects this. These messages may
- * occur at any time.
- *
- * There are two tables for mapping states because there is a second tier of
- * types for handshake messages. Once a record with a content type of handshake
- * is received, the handshake record handler will look up the handshake type in
- * the secondary map to get its appropriate handler.
- *
- * Valid message orders are as follows:

- *   PRFAlgorithm           prf_algorithm;
- *   BulkCipherAlgorithm    bulk_cipher_algorithm;
- *   CipherType             cipher_type;
- *   uint8                  enc_key_length;
- *   uint8                  block_length;
- *   uint8                  fixed_iv_length;
- *   uint8                  record_iv_length;
- *   MACAlgorithm           mac_algorithm;
- *   uint8                  mac_length;
- *   uint8                  mac_key_length;
- *   CompressionMethod      compression_algorithm;
- *   opaque                 master_secret[48];
- *   opaque                 client_random[32];
- *   opaque                 server_random[32];
- * } SecurityParameters;
- *
- * Note that this definition is from TLS 1.2. In TLS 1.0 some of these
- * parameters are ignored because, for instance, the PRFAlgorithm is a
- * builtin-fixed algorithm combining iterations of MD5 and SHA-1 in TLS 1.0.
- *
- * The Record Protocol requires an algorithm to generate keys required by the
- * current connection state.
- *
- * The master secret is expanded into a sequence of secure bytes, which is then
- * split to a client write MAC key, a server write MAC key, a client write
- * encryption key, and a server write encryption key. In TLS 1.0 a client write
- * IV and server write IV are also generated. Each of these is generated from
- * the byte sequence in that order. Unused values are empty. In TLS 1.2, some
- * AEAD ciphers may additionally require a client write IV and a server write
- * IV (see Section 6.2.3.3).
- *
- * When keys, MAC keys, and IVs are generated, the master secret is used as an
- * entropy source.
- *
- * To generate the key material, compute:
- *
- * master_secret = PRF(pre_master_secret, "master secret",
- *                     ClientHello.random + ServerHello.random)
- *
- * key_block = PRF(SecurityParameters.master_secret,
- *                 "key expansion",
- *                 SecurityParameters.server_random +
- *                 SecurityParameters.client_random);
- *
- * until enough output has been generated. Then, the key_block is
- * partitioned as follows:
- *
- * client_write_MAC_key[SecurityParameters.mac_key_length]
- * server_write_MAC_key[SecurityParameters.mac_key_length]
- * client_write_key[SecurityParameters.enc_key_length]
- * server_write_key[SecurityParameters.enc_key_length]
- * client_write_IV[SecurityParameters.fixed_iv_length]
- * server_write_IV[SecurityParameters.fixed_iv_length]
- *
- * In TLS 1.2, the client_write_IV and server_write_IV are only generated for
- * implicit nonce techniques as described in Section 3.2.1 of [AEAD]. This
- * implementation uses TLS 1.0 so IVs are generated.
- *
- * Implementation note: The currently defined cipher suite which requires the
- * most material is AES_256_CBC_SHA256. It requires 2 x 32 byte keys and 2 x 32
- * byte MAC keys, for a total 128 bytes of key material. In TLS 1.0 it also
- * requires 2 x 16 byte IVs, so it actually takes 160 bytes of key material.
- *
- * @param c the connection.
- * @param sp the security parameters to use.
- *
- * @return the security keys.

- *   message.
- *
- * Meaning of this message:
- *   With this message, the premaster secret is set, either though direct
- *   transmission of the RSA-encrypted secret, or by the transmission of
- *   Diffie-Hellman parameters which will allow each side to agree upon the
- *   same premaster secret. When the key exchange method is DH_RSA or DH_DSS,

- *   respond with a certificate which contained a Diffie-Hellman public key
- *   whose parameters (group and generator) matched those specified by the
- *   server in its certificate, this message will not contain any data.
- *
- * Meaning of this message:
- *   If RSA is being used for key agreement and authentication, the client
- *   generates a 48-byte premaster secret, encrypts it using the public key
- *   from the server's certificate or the temporary RSA key provided in a

- * Meaning of this message:
- *   This structure conveys the client's Diffie-Hellman public value
- *   (Yc) if it was not already included in the client's certificate.
- *   The encoding used for Yc is determined by the enumerated
- *   PublicValueEncoding. This structure is a variant of the client
- *   key exchange message, not a message in itself.
- *
- * When this message will be sent:
- *   This message is used to provide explicit verification of a client
- *   certificate. This message is only sent following a client
- *   certificate that has signing capability (i.e. all certificates
- *   except those containing fixed Diffie-Hellman parameters). When
- *   sent, it will immediately follow the client key exchange message.
- *
- * struct {
- *   Signature signature;
- * } CertificateVerify;
- *
- * CertificateVerify.signature.md5_hash
- *   MD5(handshake_messages);
- *
- * Certificate.signature.sha_hash
- *   SHA(handshake_messages);

- * received starting at client hello up to but not including this
- * message, including the type and length fields of the handshake
- * messages.

- * signing algorithm. A digitally-signed element is encoded as an opaque
- * vector <0..2^16-1>, where the length is specified by the signing
- * algorithm and key.
- *
- * In RSA signing, a 36-byte structure of two hashes (one SHA and one
- * MD5) is signed (encrypted with the private key). It is encoded with
- * PKCS #1 block type 0 or type 1 as described in [PKCS1].
- *

-/**
- * Creates a new TLS connection. This does not make any assumptions about the
- * transport layer that TLS is working on top of, ie: it does not assume there
- * is a TCP/IP connection or establish one. A TLS connection is totally
- * abstracted away from the layer is runs on top of, it merely establishes a
- * secure channel between a client" and a "server".
- *
- * A TLS connection contains 4 connection states: pending read and write, and
- * current read and write.
- *
- * At initialization, the current read and write states will be null. Only once
- * the security parameters have been set and the keys have been generated can
- * the pending states be converted into current states. Current states will be
- * updated for each record processed.
- *
- * A custom certificate verify callback may be provided to check information
- * like the common name on the server's certificate. It will be called for
- * every certificate in the chain. It has the following signature:
- *
- * variable func(c, certs, index, preVerify)
- * Where:
- * c         The TLS connection
- * verified  Set to true if certificate was verified, otherwise the alert
- *           tls.Alert.Description for why the certificate failed.
- * depth     The current index in the chain, where 0 is the server's cert.
- * certs     The certificate chain, *NOTE* if the server was anonymous then
- *           the chain will be empty.
- *
- * The function returns true on success and on failure either the appropriate
- * tls.Alert.Description or an object with 'alert' set to the appropriate
- * tls.Alert.Description and 'message' set to a custom error message. If true
- * is not returned then the connection will abort using, in order of
- * availability, first the returned alert description, second the preVerify
- * alert description, and lastly the default 'bad_certificate'.
- *
- * There are three callbacks that can be used to make use of client-side
- * certificates where each takes the TLS connection as the first parameter:
- *
- * getCertificate(conn, hint)
- *   The second parameter is a hint as to which certificate should be
- *   returned. If the connection entity is a client, then the hint will be
- *   the CertificateRequest message from the server that is part of the
- *   TLS protocol. If the connection entity is a server, then it will be
- *   the servername list provided via an SNI extension the ClientHello, if
- *   one was provided (empty array if not). The hint can be examined to
- *   determine which certificate to use (advanced). Most implementations
- *   will just return a certificate. The return value must be a
- *   PEM-formatted certificate or an array of PEM-formatted certificates
- *   that constitute a certificate chain, with the first in the array/chain
- *   being the client's certificate.
- * getPrivateKey(conn, certificate)
- *   The second parameter is an forge.pki X.509 certificate object that
- *   is associated with the requested private key. The return value must
- *   be a PEM-formatted private key.
- * getSignature(conn, bytes, callback)
- *   This callback can be used instead of getPrivateKey if the private key
- *   is not directly accessible in javascript or should not be. For
- *   instance, a secure external web service could provide the signature
- *   in exchange for appropriate credentials. The second parameter is a
- *   string of bytes to be signed that are part of the TLS protocol. These
- *   bytes are used to verify that the private key for the previously
- *   provided client-side certificate is accessible to the client. The
- *   callback is a function that takes 2 parameters, the TLS connection
- *   and the RSA encrypted (signed) bytes as a string. This callback must
- *   be called once the signature is ready.
- *
- * @param options the options for this connection:
- *   server: true if the connection is server-side, false for client.
- *   sessionId: a session ID to reuse, null for a new connection.
- *   caStore: an array of certificates to trust.
- *   sessionCache: a session cache to use.
- *   cipherSuites: an optional array of cipher suites to use,
- *     see tls.CipherSuites.
- *   connected: function(conn) called when the first handshake completes.
- *   virtualHost: the virtual server name to use in a TLS SNI extension.
- *   verifyClient: true to require a client certificate in server mode,
- *     'optional' to request one, false not to (default: false).
- *   verify: a handler used to custom verify certificates in the chain.
- *   getCertificate: an optional callback used to get a certificate or
- *     a chain of certificates (as an array).
- *   getPrivateKey: an optional callback used to get a private key.
- *   getSignature: an optional callback used to get a signature.
- *   tlsDataReady: function(conn) called when TLS protocol data has been
- *     prepared and is ready to be used (typically sent over a socket
- *     connection to its destination), read from conn.tlsData buffer.
- *   dataReady: function(conn) called when application data has
- *     been parsed from a TLS record and should be consumed by the
- *     application, read from conn.data buffer.
- *   closed: function(conn) called when the connection has been closed.
- *   error: function(conn, error) called when there was an error.
- *   deflate: function(inBytes) if provided, will deflate TLS records using
- *     the deflate algorithm if the server supports it.
- *   inflate: function(inBytes) if provided, will inflate TLS records using
- *     the deflate algorithm if the server supports it.

 We think of `upgrade` as a very important notion when we are talking about connections, we can see mechanisms like: stream multiplexing, congestion control, encrypted channels, multipath, simulcast, etc, as `upgrades` to a connection. A connection can be a simple and with no guarantees, drop a packet on the network with a destination thing, a transport in the other hand can be a connection and or a set of different upgrades that are mounted on top of each other, giving extra functionality to that connection and therefore `upgrading` it.

+### This module uses `pull-streams`
+
+We expose a streaming interface based on `pull-streams`, rather then on the Node.js core streams implementation (aka Node.js streams). `pull-streams` offers us a better mechanism for error handling and flow control guarantees. If you would like to know more about why we did this, see the discussion at this [issue](https://github.com/ipfs/js-ipfs/issues/362).
+
+You can learn more about pull-streams at:
+
+- [The history of Node.js streams, nodebp April 2014](https://www.youtube.com/watch?v=g5ewQEuXjsQ)
+- [The history of streams, 2016](http://dominictarr.com/post/145135293917/history-of-streams)
+- [pull-streams, the simple streaming primitive](http://dominictarr.com/post/149248845122/pull-streams-pull-streams-are-a-very-simple)
+- [pull-streams documentation](https://pull-stream.github.io/)
+
+#### Converting `pull-streams` to Node.js Streams
+
+If you are a Node.js streams user, you can convert a pull-stream to a Node.js stream using the module [`pull-stream-to-stream`](https://github.com/dominictarr/pull-stream-to-stream), giving you an instance of a Node.js stream that is linked to the pull-stream. For example:
+
+```js
+const pullToStream = require('pull-stream-to-stream')
+
+const nodeStreamInstance = pullToStream(pullStreamInstance)
+// nodeStreamInstance is an instance of a Node.js Stream
+```
+
+To learn more about this utility, visit https://pull-stream.github.io/#pull-stream-to-stream.

 dial uses the best transport (whatever works first, in the future we can have some criteria), and jump starts the connection until the point where we have to negotiate the protocol. If a muxer is available, then drop the muxer onto that connection. Good to warm up connections or to check for connectivity. If we have already a muxer for that peerInfo, then do nothing.

 > libp2p swarm implementation in JavaScript.
 
 libp2p-swarm is a connection abstraction that is able to leverage several transports and connection upgrades, such as congestion control, channel encryption, the multiplexing of several streams in one connection, and more. It does this by bringing protocol multiplexing to the application level (instead of the traditional Port level) using multicodec and multistream.

+##### `swarm.connection.enableCircuitRelay(options)`
+
+Enable circuit relaying.
+
+- `options`
+    - enabled - activates relay dialing and listening functionality
+    - hop - an object with two properties
+        - enabled - enables circuit relaying
+        - active - is it an active or passive relay (default false)
+
 ### `swarm.dial(peer, protocol, callback)`
 
 dial uses the best transport (whatever works first, in the future we can have some criteria), and jump starts the connection until the point where we have to negotiate the protocol. If a muxer is available, then drop the muxer onto that connection. Good to warm up connections or to check for connectivity. If we have already a muxer for that peerInfo, then do nothing.

-> libp2p swarm implementation in JavaScript.
+> libp2p-switch is a dialar machine, it leverages the multiple libp2p transports, stream muxers, crypto channels and other connection upgrades to dial to peers in the libp2p network. It also supports Protocol Multiplexing through a multicodec and multistream-select handshake.
 
-libp2p-swarm is a connection abstraction that is able to leverage several transports and connection upgrades, such as congestion control, channel encryption, the multiplexing of several streams in one connection, and more. It does this by bringing protocol multiplexing to the application level (instead of the traditional Port level) using multicodec and multistream.

 ## Install
 
-libp2p-swarm is available on npm and so, like any other npm module, just:
-
 ```bash
-> npm install libp2p-swarm --save
+> npm install libp2p-switch --save
 ```
 
 ## Usage
 
-### Create a libp2p Swarm
-
-And use it in your Node.js code as:
+### Create a libp2p Switch
 
 ```JavaScript
-const Swarm = require('libp2p-swarm')
+const switch = require('libp2p-switch')
 
-const sw = new Swarm(peerInfo [, peerBook])
+const sw = new switch(peerInfo [, peerBook])
 ```
 
 ## API
 
-peerInfo is a [PeerInfo](https://github.com/libp2p/js-peer-info) object that represents the peer creating this swarm instance.
+- peerInfo is a [PeerInfo](https://github.com/libp2p/js-peer-info) object that has the peer information.
+- peerBook is a [PeerBook](https://github.com/libp2p/js-peer-book) object that stores all the known peers.

-We expose a streaming interface based on `pull-streams`, rather then on the Node.js core streams implementation (aka Node.js streams). `pull-streams` offers us a better mechanism for error handling and flow control guarantees. If you would like to know more about why we did this, see the discussion at this [issue](https://github.com/ipfs/js-ipfs/issues/362).

-#### Converting `pull-streams` to Node.js Streams
-
-If you are a Node.js streams user, you can convert a pull-stream to a Node.js stream using the module [`pull-stream-to-stream`](https://github.com/pull-stream/pull-stream-to-stream), giving you an instance of a Node.js stream that is linked to the pull-stream. For example:
-
+##### `switch.transport.listen(key, options, handler, callback)`
 
+Set a transport to start listening mode.
 
-```js
-const pullToStream = require('pull-stream-to-stream')
-
-const nodeStreamInstance = pullToStream(pullStreamInstance)
-// nodeStreamInstance is an instance of a Node.js Stream
-```
+- `key`
+- `options`
+- `handler`
+- `callback`

+##### `switch.transport.close(key, callback)`
 
+Close the listeners of a given transport.

+### This module uses `pull-streams`
+
+We expose a streaming interface based on `pull-streams`, rather then on the Node.js core streams implementation (aka Node.js streams). `pull-streams` offers us a better mechanism for error handling and flow control guarantees. If you would like to know more about why we did this, see the discussion at this [issue](https://github.com/ipfs/js-ipfs/issues/362).

+### Stats API
+
+##### `switch.stats.emit('update')`
+
+Every time any stat value changes, this object emits an `update` event.
+
+#### Global stats
+
+##### `switch.stats.global.snapshot`
+
+Should return a stats snapshot, which is an object containing the following keys and respective values:
+
+- dataSent: amount of bytes sent, [Big](https://github.com/MikeMcl/big.js#readme) number
+- dataReceived: amount of bytes received, [Big](https://github.com/MikeMcl/big.js#readme) number
+
+##### `switch.stats.global.movingAverages`
+
+Returns an object containing the following keys:
+
+- dataSent
+- dataReceived
+
+Each one of them contains an object that has a key for each interval (`60000`, `300000` and `900000` miliseconds).
+
+Each one of these values is [an exponential moving-average instance](https://github.com/pgte/moving-average#readme).
+
+#### Per-transport stats
+
+##### `switch.stats.transports()`
+
+Returns an array containing the tags (string) for each observed transport.
+
+##### `switch.stats.forTransport(transportTag).snapshot`
+
+Should return a stats snapshot, which is an object containing the following keys and respective values:
+
+- dataSent: amount of bytes sent, [Big](https://github.com/MikeMcl/big.js#readme) number

+
+#### Per-protocol stats
+
+##### `switch.stats.protocols()`
+
+Returns an array containing the tags (string) for each observed protocol.
+
+##### `switch.stats.forProtocol(protocolTag).snapshot`
+
+Should return a stats snapshot, which is an object containing the following keys and respective values:
+
+- dataSent: amount of bytes sent, [Big](https://github.com/MikeMcl/big.js#readme) number
+- dataReceived: amount of bytes received, [Big](https://github.com/MikeMcl/big.js#readme) number

+
+#### Per-peer stats
+
+##### `switch.stats.peers()`
+
+Returns an array containing the peerIDs (B58-encoded string) for each observed peer.
+
+##### `switch.stats.forPeer(peerId:String).snapshot`
+
+Should return a stats snapshot, which is an object containing the following keys and respective values:
+
+- dataSent: amount of bytes sent, [Big](https://github.com/MikeMcl/big.js#readme) number
+- dataReceived: amount of bytes received, [Big](https://github.com/MikeMcl/big.js#readme) number

+
+Each one of these values is [an exponential moving-average instance](https://github.com/pgte/moving-average#readme).
+
+#### Stats update interval
+
+Stats are not updated in real-time. Instead, measurements are buffered and stats are updated at an interval. The maximum interval can be defined through the `Switch` constructor option `stats.computeThrottleTimeout`, defined in miliseconds.

Subject: [PATCH 495/634] fix: drop connection when stream ends unexpectedly

Pull streams pass true in the error position when the sream ends.
In https://github.com/multiformats/js-multistream-select/blob/5b19358b91850b528b3f93babd60d63ddcf56a99/src/select.js#L18-L21
...we're getting lots of instances of pull-length-prefixed stream
erroring early with `true` and it's passed back up to the dialer
in https://github.com/libp2p/js-libp2p-switch/blob/fef2d11850379a4720bb9c736236a81a067dc901/src/dial.js#L238-L241

The `_createMuxedConnection` contains an assumption that any error
that occurs when trying `_attemptMuxerUpgrade` is ok, and keeps the
relveant baseConnecton in the cache. If the pull-stream has ended
unexpectedly then keeping the connection arround starts causing
the "already piped" errors when we try and use the it later.

This PR adds a guard to avoid putting the connection back into the
cache if the stream has ended.

There is related work in an old PR to add a check for exactly this issue in
pull-length-prefixed https://github.com/dignifiedquire/pull-length-prefixed/pull/8
...but it's still open, so this PR adds a check for true in
the error position at the site where the "already piped" errors
were appearing. Once the PR on pull-length-prefixed is merged this
check can be removed. It's not ideal to have it in this code as it
is far removed from the source, but it fixes the issue for now.

Arguably anywhere that `msDialer.handle` is called should do the
same check, but we're not seeing this error occur anywhere else so
to keep this PR small, I've left it as the minimal changeset to
fix the issue.

Of note, we had to add '/dns4/ws-star.discovery.libp2p.io/tcp/443/wss/p2p-websocket-star'
to the swarm config to trigger the "already piped" errors. There
is a minimal test app here https://github.com/tableflip/js-ipfs-already-piped-error

Manual testing shows ~50 streams fail in the first 2 mins of
running a node, and then things stabalise with ~90 active muxed
connections after that.

Fixes #235
Fixes https://github.com/ipfs/js-ipfs/issues/1366
See https://github.com/dignifiedquire/pull-length-prefixed/pull/8

 dial uses the best transport (whatever works first, in the future we can have some criteria), and jump starts the connection until the point where we have to negotiate the protocol. If a muxer is available, then drop the muxer onto that connection. Good to warm up connections or to check for connectivity. If we have already a muxer for that peerInfo, then do nothing.

Subject: [PATCH 552/634] fix: dial in series until we have proper abort
 support (#306)

refactor: simplify the circuit dial logic

chore: remove travis windows cache

refactor: clean up dial many error logic

test: explicitly set correct address

test(refactor): update order of echo logic and add after

refactor: cleanup per feedback

Subject: [PATCH 558/634] feat: add basic dial queue to avoid many connections
 to peer (#310)

BREAKING CHANGE: This adds a very basic dial queue peer peer.
This will prevent multiple, simultaneous dial requests to the same
peer from creating multiple connections. The requests will be queued
per peer, and will leverage the same connection when possible.
The breaking change here is that `.dial`, will no longer return a
connection. js-libp2p, circuit relay, and kad-dht, which use `.dial`
were not using the returned connection. So while this is a breaking change
it should not break the existing libp2p stack. If custom applications
are leveraging the returned connection, they will need to convert to only
using the connection returned via the callback.

* chore: dont log priviatized unless it actually happened
* refactor: only get our addresses for filtering once

+# [0.42.0](https://github.com/libp2p/js-libp2p-switch/compare/v0.41.7...v0.42.0) (2019-03-21)
+
+
+### Features
+
+* add basic dial queue to avoid many connections to peer ([#310](https://github.com/libp2p/js-libp2p-switch/issues/310)) ([6a94d9a](https://github.com/libp2p/js-libp2p-switch/commit/6a94d9a))
+* update identify to include supported protocols ([#311](https://github.com/libp2p/js-libp2p-switch/issues/311)) ([46e2509](https://github.com/libp2p/js-libp2p-switch/commit/46e2509))
+
+
+### BREAKING CHANGES
+
+* This adds a very basic dial queue peer peer.
+This will prevent multiple, simultaneous dial requests to the same
+peer from creating multiple connections. The requests will be queued
+per peer, and will leverage the same connection when possible.
+The breaking change here is that `.dial`, will no longer return a
+connection. js-libp2p, circuit relay, and kad-dht, which use `.dial`
+were not using the returned connection. So while this is a breaking change
+it should not break the existing libp2p stack. If custom applications
+are leveraging the returned connection, they will need to convert to only
+using the connection returned via the callback.
+
+* chore: dont log priviatized unless it actually happened
+* refactor: only get our addresses for filtering once
+

Subject: [PATCH 562/634] fix: ensure dials always use the latest PeerInfo from
 the PeerBook (#312)

* fix: ensure dials always use the latest PeerInfo from the PeerBook

This fixes an issue where if dial is called with a new instance
of PeerInfo, if it is the first dial to that peer, the queue was
forever associated with that instance. This is currently the case
when Circuit checks the HOP status of a potential relay. This ensures
that whenever we dial, we are updating the peer book and using the
latest PeerInfo in that dial request.

* test: add test for get peer info

* refactor: just use id with dialer queue

This should be used when an application only wishes to establish connections to new peers, such as during peer discovery when there is a low peer count.

Subject: [PATCH 601/634] fix: dont blindly add observed addresses to our list
 (#337)

Until we can properly validate the observed address our
peer tells us about, we shouldnt blindly add it to our
address list. Until we have better NAT management we cant
reliably validate that we're adding an appropriate address
for ourselves.

-
-
-### BREAKING CHANGES
-
-* This adds a very basic dial queue peer peer.
-This will prevent multiple, simultaneous dial requests to the same
-peer from creating multiple connections. The requests will be queued
-per peer, and will leverage the same connection when possible.
-The breaking change here is that `.dial`, will no longer return a
-connection. js-libp2p, circuit relay, and kad-dht, which use `.dial`
-were not using the returned connection. So while this is a breaking change
-it should not break the existing libp2p stack. If custom applications
-are leveraging the returned connection, they will need to convert to only
-using the connection returned via the callback.
-
-* chore: dont log priviatized unless it actually happened
-* refactor: only get our addresses for filtering once

Subject: [PATCH 607/634] fix: make subscribe comply with ipfs interface (#389)

BREAKING CHANGE: The ipfs interface specified that options
should be provided after the handler, not before.
https://github.com/ipfs/interface-js-ipfs-core/blob/v0.109.0/SPEC/PUBSUB.md#pubsubsubscribe

This corrects the order of parameters. See the jsdocs examples
for subscribe to see how it should be used.

Subject: [PATCH 610/634] feat: integrate gossipsub by default (#365)

BREAKING CHANGE: new configuration for deciding the implementation of pubsub to be used.
In this context, the experimental flags were also removed. See the README for the latest usage.

+
+
+### Bug Fixes
+
+* make subscribe comply with ipfs interface ([#389](https://github.com/libp2p/js-libp2p/issues/389)) ([9554b05](https://github.com/libp2p/js-libp2p/commit/9554b05))
+
+
+### Features
+
+* integrate gossipsub by default ([#365](https://github.com/libp2p/js-libp2p/issues/365)) ([791f39a](https://github.com/libp2p/js-libp2p/commit/791f39a))
+* promisify all api methods that accept callbacks ([#381](https://github.com/libp2p/js-libp2p/issues/381)) ([df6ef45](https://github.com/libp2p/js-libp2p/commit/df6ef45))
+
+
+### BREAKING CHANGES
+
+* new configuration for deciding the implementation of pubsub to be used.
+In this context, the experimental flags were also removed. See the README for the latest usage.
+* The ipfs interface specified that options
+should be provided after the handler, not before.
+https://github.com/ipfs/interface-js-ipfs-core/blob/v0.109.0/SPEC/PUBSUB.md#pubsubsubscribe
+
+This corrects the order of parameters. See the jsdocs examples
+for subscribe to see how it should be used.

* docs: update browser example pubsub

* docs: fix pubsub example config

* fix: make pubsub default to enabled

This allows for only adding the module to have it enabled. Previously you would have to supply and enable the module which is unncessary for users

Subject: [PATCH 617/634] refactor: blacklist to denylist (#341)

"denylist" more adequately describes what this list is for.

BREAKING CHANGE: Constructor options `blacklistTTL` and `blackListAttempts` have been renamed to `denyTTL` and `denyAttempts`. The error code from errors thrown when dial is currently denied has changed from `ERR_BLACKLISTED` to `ERR_DENIED`.

+
+### Code Refactoring
+
+* blacklist to denylist ([#341](https://github.com/libp2p/js-libp2p-switch/issues/341)) ([f64c73b](https://github.com/libp2p/js-libp2p-switch/commit/f64c73b))

+
+### BREAKING CHANGES
+
+* Constructor options `blacklistTTL` and `blackListAttempts` have been renamed to `denyTTL` and `denyAttempts`. The error code from errors thrown when dial is currently denied has changed from `ERR_BLACKLISTED` to `ERR_DENIED`.

+
+
+### Chores
+
+* update switch ([#395](https://github.com/libp2p/js-libp2p/issues/395)) ([684f283](https://github.com/libp2p/js-libp2p/commit/684f283))
+
+
+### BREAKING CHANGES
+
+* switch configuration has changed.

 ## Usage
 
+**IMPORTANT NOTE**: We are currently on the way of migrating all our `libp2p` modules to use `async await` and `async iterators`, instead of callbacks and `pull-streams`. As a consequence, when you start a new libp2p project, we must check which versions of the modules you should use. For now, it is required to use the modules using callbacks with `libp2p`, while we are working on getting the remaining modules ready for a full migration. For more details, you can have a look at [libp2p/js-libp2p#266](https://github.com/libp2p/js-libp2p/issues/266).
+
 ### [Tutorials and Examples](/examples)
 
 You can find multiple examples on the [examples folder](/examples) that will guide you through using libp2p for several scenarios.
