Args:
key (bytes/bytearray/memoryview):
The key to use to compute the MAC.
It must be at least 128 bits long (16 bytes).
data (bytes/bytearray/memoryview):
Optional. The very first chunk of the message to authenticate.
It is equivalent to an early call to :meth:`KMAC_Hash.update`.
mac_len (integer):
Optional. The size of the authentication tag, in bytes.
Default is 64. Minimum is 8.
custom (bytes/bytearray/memoryview):
Optional. A customization byte string (``S`` in SP 800-185).
Returns:
A :class:`KMAC_Hash` hash object
