NAME         top

       gnutls_pubkey_get_preferred_hash_algorithm - API function

SYNOPSIS         top

       #include <gnutls/abstract.h>

       int gnutls_pubkey_get_preferred_hash_algorithm(gnutls_pubkey_t
       key, gnutls_digest_algorithm_t *         hash, unsigned int *
       mand);

ARGUMENTS         top

       gnutls_pubkey_t key
                   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.

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).

       To get the signature algorithm instead of just the hash use
       gnutls_pk_to_sign() with the algorithm of the certificate/key and
       the provided  hash .

RETURNS         top

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

SINCE         top

       2.12.0
