Ah, of course! I had not thought of that. By the way, everybody should take a look at the "Stick Figure Guide to the Advanced Encryption Standard (AES)": http://www.moserware.com/ -- Martin Geisler VIFF (Virtual Ideal Functionality Framework) brings easy and efficient SMPC (Secure Multiparty Computation) to Python.
