Create a new HMAC object. 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. z9This class is not available in FIPS mode.
