gnutls_x509_crt_get_preferred_hash_algorithm - API function
#include <gnutls/compat.h> int gnutls_x509_crt_get_preferred_hash_algorithm(gnutls_x509_crt_t crt, gnutls_digest_algorithm_t * hash, unsigned int * mand);
gnutls_x509_crt_t crt Holds the certificate gnutls_digest_algorithm_t * hash The result of the call with the hash algorithm used for signature unsigned int * mand 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 certificates (i.e. DSA might not be able to sign without the preferred algorithm).
Please use gnutls_pubkey_get_preferred_hash_algorithm().
the 0 if the hash algorithm is found. A negative error code is returned on error.
