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 certifcate and return the appropriate digest algorithm to use for signing with this certificate. Some  certifi-
       cates (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
