gnutls_pubkey_get_preferred_hash_gnugnutlsbkey_get_preferred_hash_algorithm(3)

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  di-
       gest  algorithm to use for signing with this certificate. Some certifi-
       cates (i.e.  DSA	might not be able to sign without the preferred	 algo-
       rithm).

       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
