This website is an ongoing project to understand various types of cryptographic ciphers used to represent information in a different way.

<tr>
<td>Atbash</td>
<td>monoalphabetic substitution cipher originally used by Hebrews to encrypt the Torah and essentially uses a reversed alphabet</td>
</tr>
<tr>
<td>Base16</td>
<td>commonly known as 'hexadecimal' an encoding scheme which translate ASCII into radix-16, and used to represent binary data in a compact form</td>
</tr>
<tr>
<td>Base32</td>
<td>an encoding scheme which translates ASCII into radix-32 representation, resulting character set is one-case and is beneficial for case-insenstive transmissions</td>
</tr>
<tr>
<td>Base64</td>
<td>an encoding scheme which translates ASCII into radix-64 representation, used to transfer binary data through text only channels e.g. HTTP</td>
</tr>
<tr>
<td>Caesar</td>
<td>a shift cipher named after Julius Caesar, which utilises numeric shifts to displace each letter of a text by the same integer value</td>
</tr>
<tr>
<td>Playfair</td>
<td>also known as "playfair square" or "wheatstone playfair" uses digrapm substitution scheme. which encrypts pairs of letters against a 5x5 grid</td>
</tr>
<tr>
<td>Polybius</td>
<td>Polybius square uses a 5x5 grid of the alphabet excluding one character. the algorithm looks up each character on the grid and returns their coordinates vice-versa. </td>
</tr>
<tr>
<td>Reversal</td>
<td>this is a modified version of the Reversal Cipher which only reverses each word and does not reverse the sentence itself</td>
</tr>
<tr>
<td>Rot13</td>
<td>a special case of the Caesar Cipher which has an integer key of 13, encryption and decryption are the inverse of each other</td>
</tr>
<tr>
<td>Vigenere</td>
<td>a shift cipher that uses a series of interwoven Caesar Ciphers together shifting each character by a different value depending on the cipher key</td>
</tr>
<tr>
<td>Beaufort</td>
<td>a shift cipher similar to vigenere which also uses a tabula recta. with an algorithm that encrypts each character in the reverse direction.</td>
</tr>
<tr>
<td>Autokey</td>
<td>also known as 'autoclave cipher' a complete copy of the vigenere algorithm but combines the message with the key to generate it dynamically.</td>
</tr>
