Elliptic Curves - project site

Thank you very much for using this site!
Thanks to all the students, teachers and professors around the planet who find these tools useful.
Don't hesitate to contact me in case of questions about the applications below.

This site is developed as part of my master thesis in cryptology 2010.

For demonstrational use. Not optimized for professional use!

ECC - Menezes Vanstone Elliptic Curve ElGamal Cryptosystem (Suite B NIST curves, P192-P512)

Point calculation on ECC with Suite B

Elliptic Curve Calculator for any curve <-- the popular one...:-)
