NAME
       gnutls_pubkey_get_preferred_hash_algorithm - API function

SYNOPSIS
       #include <gnutls/abstract.h>

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

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

SINCE
       2.12.0
