__init__(self, key, msg=None, digestmod=None)
(Constructor)

key:       key for the keyed hash object.
msg:       Initial input for the hash, if provided.
digestmod: A module supporting PEP 247.  *OR*
           A hashlib constructor returning a new hash object.
           Defaults to hashlib.md5.

copy(self)

 

Return a separate copy of this hashing object.

An update to this copy won't affect the original object.
