The standard library already provides for cryptographic hashes (hashlib) and MACs (hmac).

[snip] Therefore, I would suggest either adding a new module (name tbd) or adding new constructors to hashlib.

PBKDF2 can be implemented in 15 lines of code based on the hmac and hashlib modules:

https://github.com/mitsuhiko/python-pbkdf2/blob/master/pbkdf2.py

Although the code is short, it is easy to get wrong. So I think it would be nice to have in the stdlib, tested once and for all.

Also, PBKDF2 is a well-defined spec that will not change (or it will be called PBKDF3 or something) which I think makes it a good fit for the stdlib.

I would suggest to have Armin’s implementation (linked above) included as-is, but it’s probably too late for 3.3.
