This supports the API for Cryptographic Hash Functions (PEP 247).

key: key for the keyed hash object.
msg: Initial input for the hash, if provided.
digestmod: A module supporting PEP 247. Defaults to the md5 module.

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

This returns a string containing 8-bit data. The object is
not altered in any way by this function; you can continue
updating the object after calling this function.

key: The starting key for the hash.
msg: if available, will immediately be hashed into the object's starting
state.
You can now feed arbitrary strings into the object using its update()
method, and can ask for the hash value at any time by calling its digest()
method.
