Tracker issue for the hashlib PBKDF2 and algorithm availability details backport to 2.7 described in PEP 466.

issue21304 has the implementation of the PBKDF2 work.

Let's dup this then.

Rather #21304 should be a dep...

Uploaded patch adds the algorithm availability constants to the hashlib module.

use a frozenset for algorithms_guaranteed.

in the docs under more algor... may be available make the two variables
link to their docs.  you might explicitly mention python 2.7.9 in that
paragraph.

you probably should use pystring_fromstring imstead of unicode given this
is 2.7.

New patch uses PyString_FromString.

To the other two points:

1) Python3 uses a mutable set for both of these, any reason for Python2 to be inconsistent?

2) The docs in Python3 don't have this link either, I'm trying to minimize the delta; if you think there should be a link I'd prefer it be done in python3, and then I can backport that as well.

Keeping the delta small makes sense. I'd use frozenset in 3 as well but its
unimportant. LGTM.

This Look good to me. +1
