Args:
data (bytes/bytearray/memoryview):
The very first chunk of the message to hash.
It is equivalent to an early call to :meth:`Keccak_Hash.update`.
digest_bytes (integer):
The size of the digest, in bytes (28, 32, 48, 64).
digest_bits (integer):
The size of the digest, in bits (224, 256, 384, 512).
update_after_digest (boolean):
Whether :meth:`Keccak.digest` can be followed by another
:meth:`Keccak.update` (default: ``False``).
