|
a° Create a new Poly1305 MAC object.
|
|
Args:
|
key (bytes/bytearray/memoryview):
|
The 32-byte key for the Poly1305 object.
|
cipher (module from ``Crypto.Cipher``):
|
The cipher algorithm to use for deriving the Poly1305
|
key pair *(r, s)*.
|
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. The very first chunk of the message to authenticate.
|
It is equivalent to an early call to ``update()``.
|
|
Returns:
|
A :class:`Poly1305_MAC` object
