class Eth::Key::Encrypter

def initialize(key, options = {})

Options Hash: (**options)
  • :block_size (Integer) -- for scrypt, defaults to 1
  • :parallelization (Integer) -- parallelization factor for scrypt, defaults to 8
  • :iv (String) -- 128-bit initialisation vector for the cipher
  • :salt (String) -- passed to PBKDF
  • :iterations (String) -- number of iterations for the hash function
  • :id (String) -- uuid given to the secret key
  • :kdf (String) -- key derivation function defaults to pbkdf2

Parameters:
  • options (Hash) -- the options to encrypt with
  • key (Eth::Key) -- representing a secret key-pair used for encryption

  # however, if an option is given then it must be either pbkdf2 or scrypt
