Cool -- that sounds like a good opportunity to finally sit down and create a slow-but-simple elliptic curve library for VIFF. I suggest you to use some library instead. Some of the algorithms are quite involved... I'm sure you can find C/C++ good stuff out there, and as far as I understood, you

From reading the Wikipedia page linked below it seems very simple to implement. But if it should be fast, then a library is of course much better than a home-grown Python version. It's also about security. I would like an implementation that deals, at least, with the most common side-channel
