The `encoding` can be `'hex'`, `'binary'` or `'base64'`.
### crypto.createCipher(algorithm, key)
### crypto.createCipher(algorithm, password)
Creates and returns a cipher object, with the given algorithm and key.
Creates and returns a cipher object, with the given algorithm and password.
`algorithm` is dependent on OpenSSL, examples are `'aes192'`, etc.
On recent releases, `openssl list-cipher-algorithms` will display the available cipher algorithms.
On recent releases, `openssl list-cipher-algorithms` will display the
available cipher algorithms.
`password` is used to derive key and IV, which must be `'binary'` encoded
string (See the [Buffers](buffers.html) for more information).
### crypto.createCipheriv(algorithm, key, iv)
Creates and returns a cipher object, with the given algorithm, key and iv.
`algorithm` is the same as the `createCipher()`. `key` is a raw key used in
algorithm. `iv` is an Initialization vector. `key` and `iv` must be `'binary'`
encoded string (See the [Buffers](buffers.html) for more information).
### cipher.update(data, input_encoding='binary', output_encoding='binary')

Returns any remaining enciphered contents, with `output_encoding` being one of: `'binary'`, `'base64'` or `'hex'`.
### crypto.createDecipher(algorithm, key)
### crypto.createDecipher(algorithm, password)
Creates and returns a decipher object, with the given algorithm and key.
This is the mirror of the cipher object above.
This is the mirror of the [createCipher()](#crypto.createCipher) above.
