Args: key (bytes/bytearray/memoryview): The 32-byte key for the Poly1305 object. cipher (module from ``Cryptodome.Cipher``): The cipher algorithm to use for deriving the Poly1305 key pair *(r, s)*. It can only be ``Cryptodome.Cipher.AES`` or ``Cryptodome.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. The very first chunk of the message to authenticate. It is equivalent to an early call to ``update()``.
