/* LibTomCrypt, modular cryptographic library -- Tom St Denis
 * LibTomCrypt is a library that provides various cryptographic
 * algorithms in a highly modular and flexible manner.
 * The library is free for all purposes without any express
 * guarantee it works.

/* Implements ECC over Z/pZ for curve y^2 = x^3 - 3x + b
 * All curves taken from NIST recommendation paper of July 1999
 * Available at
