As 3.2 and 3.3 have lost support as of some time last year, I wouldn't worry much about supporting them.

Looks like an easy fix, though:

RuntimeError: cryptography requires setuptools 18.5 or newer, please upgrade to a newer version of setuptools

If that can be fixed with a simple touch, I would rather keep it compatible with 3.2 and 3.3.
