gnutls_x509_crt_get_preferred_hgnutls_x509_crt_get_preferred_hash_algorithm(3)

NAME
       gnutls_x509_crt_get_preferred_hash_algorithm - API function

SYNOPSIS
       #include <gnutls/compat.h>

       int gnutls_x509_crt_get_preferred_hash_algorithm(gnutls_x509_crt_t crt,
       gnutls_digest_algorithm_t					     *
       hash, unsigned int * mand);

ARGUMENTS
       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 be NULL.

DESCRIPTION
       This function will read	the  certifcate	 and  return  the  appropriate
       digest  algorithm  to  use for signing with this certificate. Some cer‐
       tificates (i.e.	DSA might not be able to sign  without	the  preferred
       algorithm).

DEPRECATED
       Please use gnutls_pubkey_get_preferred_hash_algorithm().

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

SINCE
       2.12.0
