The PyCrypto library provides Python with implementation for a lot of algorithms for cryptography. It's very useful.

Ubuntu has it by default but if you want to have it for Python 3.2 on Windows, you must use Active Python, as there is no other binary release for Python 3.2 on the web.

In case you want to use the official Python distribution or if ActiveState did not (yet) released a PyCrypto for the version of Python you are using, this article might help you by putting together the steps to build it from source.
