Member Function Documentation

new()

wolfcrypt.hashes._Hmac.new	(		cls,
			key,
			string = None )

Creates a new hashing object and returns it. **key** is
a required parameter containing a string giving the key
to use. The optional **string** parameter, if supplied,
will be immediately hashed into the object's starting
state, as if obj.update(string) was called.
