Hi, I am upgrading some 3RD party code which performs FIPS ECDSA AVS testing for FIPS 140-2 certification. The code uses FIPS_escda_sign(), which in Openssl-fips-2.0.5 is define as: ECDSA_SIG * FIPS_ecdsa_sign(EC_KEY *key, const unsigned char *msg, size_t msglen , const EVP_MD *mhash) The full code is here: https://github.com/majek/openssl/blob/master/fips/ecdsa/fips_ecdsavs.c I have read through all of the ECDSA sign man pages, and I cannot find a functions that is close to accepting some of the same parameter. I could use some help please. I have very little experience with ECDSA. Thanks, Kory
