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.
