It can only be ``Crypto.Cipher.AES`` or ``Crypto.Cipher.ChaCha20``. nonce (bytes/bytearray/memoryview): Optional. The non-repeatable value to use for the MAC of this message. It must be 16 bytes long for ``AES`` and 8 or 12 bytes for ``ChaCha20``. If not passed, a random nonce is created; you will find it in the ``nonce`` attribute of the new object. data (bytes/bytearray/memoryview): Optional.
