int gnutls_x509_crt_get_preferred_hash_algorithm(gnutls_x509_crt_t crt,
gnutls_digest_algorithm_t * hash, unsigned int * mand);
Holds the certificate

If non-zero it means that the algorithm MUST use this hash.
May be NULL.
This function will read the certificate and return the appropriate
digest algorithm to use for signing with this certificate. Some
