[Python-Dev] PEP 247 and hashlib

"PEP 247 -- API for Cryptographic Hash Functions" specifies a standard
API for hashing modules.

... the optional 'string' parameter, if supplied, will be immediately
hashed into the object's starting state, as if obj.update(string) was

But hashlib.new() takes the algorithm name... Does PEP need an update?

By the way, I am thinking about mapping .NET's
System.Security.Cryptography.HashAlgorithm.Create and created object's
ComputeHash method to Python's hash API for IronPython. For that, I'd
like to see a clarification.
