Code to fuzz bignum libraries

CVE-2015-3193-openssl-vs-gcrypt-modexp.c

This is a simple test that will do a calculation that some versions of OpenSSL will get wrong and compare the result with libgcrypt.

openssl-vs-gcrypt-modexp.c

This is a sample code to fuzz the BN_mod_exp() function of OpenSSL and the gcry_mpi_powm() function of libgcrypt.

Usage instructions are in the code.
