New submission from Jonas Borgström:
Problem:
In hmac.py there's a type check that verifies that the msg parameter is of type
bytes().
if not isinstance(msg, bytes):
raise TypeError("expected bytes, but got %r" % type(msg).__name__)
That is incorrect. The hmac module should also work with other data types as
long as they are supported by the underlying hashlib module, for example
bytearray() and memoryview().
Suggestion:
Remove that type check. hashlib will make sure str() and other invalid data
types raises a TypeError.
