key: bytes or buffer, key for the keyed hash object.
msg: bytes or buffer, Initial input for the hash or None.
digestmod: A hash name suitable for hashlib.new(). *OR*
A hashlib constructor returning a new hash object. *OR*
A module supporting PEP 247.
Required as of 3.8, despite its position after the optional
msg argument. Passing it as a keyword argument is
recommended, though not required for legacy API reasons.
