Hi, maybe I'm a little late but today scanning through "The daily
Python-URL" I came through something that might be pertinent.

The link is http://www.keyczar.org/
And here is the intro to the site :
"""
Keyczar is an open source cryptographic toolkit designed to make it
easier and safer for developers to use cryptography in their
applications. Keyczar supports authentication and encryption with both
symmetric and asymmetric keys. Some features of Keyczar include:

    * A simple API
    * Key rotation and versioning
    * Safe default algorithms, modes, and key lengths
    * Automated generation of initialization vectors and ciphertext
signatures
    * Java and Python implementations (C++ coming soon)
    * International support in Java (Python coming soon)

Keyczar was originally developed by members of the Google Security Team
and is released under an Apache 2.0 license.
