Cryptography ============ .. image:: https://travis-ci.org/alex/cryptography.png?branch=master :target: https://travis-ci.org/alex/cryptography ``cryptography`` is a package designed to expose cryptographic primitives and recipes to Python developers. It is currently in early development and isn't recommended for general usage yet. It targets Python 2.6-2.7, Python 3.2+, as well as PyPy. Why a new crypto library for Python? ------------------------------------ None of the existing ones work on PyPy, and many of them are unmaintained or are based around very poor implementations of algorithms (i.e ones with known side-channel attacks).
