girazoki / ecvrf

INSECURE and INEFFICIENT reference implementation for the ECVRF (all four specified there). Requires GMP and NTL.

!!!!!!!!!!!!!!!!!!!!!!!!! WARNING !!!!!!!!!!!!!!!!!!!!!!!!!

THIS CODE IS INSECURE AND NOT TO BE USED FOR ACTUAL CRYPTO!!! IT IS ALSO INEFFICIENT AND COBBLED TOGETHER TOO QUICKLY TO BE ANY GOOD!!! DO NOT USE IT!!!

It was written as a reference implementation only, in order to generate test vectors.

Compiling notes: if you are having trouble compiling, check what version of GMP and NTL you have. Mine worked with GMP 6.1.2 and NTL 10.5.0. In particular, earlier versions of the NTL may require you to add a few more #include declarations:

#include<stdio.h>
#include<string.h>
#include<stdlib.h>
#include<NTL/ZZ.h>
#include<NTL/ZZ_p.h>

Also, conversion from string to ZZ_p may not work directly; you may have to convert to ZZ first and then to ZZ_p.
