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.
