The copy will have the same internal state as the original HMAC
object.
This can be used to efficiently compute the MAC tag of byte
strings that share a common initial substring.

Nc $ t | || S )a= Create a new MAC object.
Args:
key (bytes/bytearray/memoryview):
key for the MAC object.
It must be long enough to match the expected security level of the
MAC.
msg (bytes/bytearray/memoryview):
Optional. The very first chunk of the message to authenticate.
It is equivalent to an early call to :meth:`HMAC.update`.
digestmod (module):
The hash to use to implement the HMAC.
Default is :mod:`Crypto.Hash.MD5`.
Returns:
An :class:`HMAC` object
