Keystore generation

[ceres3idoo]

📝 Feature

As a user I want to generate my personal keystore file using a cli command.

📖 Details

The command should be:

eidoo-hybrid-exchange-cli ethereum-wallet key-generate
--keystore-file-path The destination file path where keystore will be stored
[--hd-path] The derivation path used to retrieve the private key from seed. (default: m/44'/60'/0/0)

so you need to type your seed (12 words) and after that you have to insert a password (used to build the keystore json file).

The output will be a json file strucred as follows:

{
    "address": "fakeAddress",
    "crypto": {
        "cipher": "aes-128-ctr",
        "ciphertext": "fakeChyper",
        "cipherparams": {
            "iv": "fakeIv"
        },
        "mac": "fakeMac",
        "kdf": "scrypt",
        "kdfparams": {
            "dklen": 32,
            "n": 262144,
            "r": 1,
            "p": 8,
            "salt": "fakesalt"
        }
    },
    "id": "f99105b6-ef46-418c-9811-13a4f6004b70",
    "version": 3
}

Under the hood will be used keythereum dump generating a keystore file.

const options = const options = {
  kdf: "scrypt",
  cipher: "aes-128-ctr",
  kdfparams: {
    c: 262144,
    dklen: 32,
    prf: "hmac-sha256"
  }
}
// privateKey retrieved from hd_path and mnemonic
const iv = randomBytes
const salt = randomBytes
const result = keythereum.dump(password, privateKey, salt, iv, options)
