Cool, that is a speedup of 5.5!

Calling a ElGamal function in NaCl would be very cool and probably a bit faster since you wont have to do all the tuple packing and unpacking that you do in the Python version. -- Martin Geisler VIFF (Virtual Ideal Functionality Framework) brings easy and efficient SMPC (Secure Multi-Party Computation) to Python.
