NAME        top

       gnutls_x509_crt_get_preferred_hash_algorithm - API function

SYNOPSIS        top

#include <gnutls/compat.h>int gnutls_x509_crt_get_preferred_hash_algorithm(gnutls_x509_crt_tcrt, gnutls_digest_algorithm_t *hash, unsigned int *mand);

ARGUMENTS        top

       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 beNULL.

DESCRIPTION        top

       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).

DEPRECATED        top

       Please usegnutls_pubkey_get_preferred_hash_algorithm().

RETURNS        top

       the 0 if the hash algorithm is found. A negative error code is       returned on error.

SINCE        top

       2.12.0
