Имя (Name)

gnutls_pubkey_get_preferred_hash_algorithm - API function

Синопсис (Synopsis)

#include <gnutls/abstract.h>

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

Аргументы (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.

Описание (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 .

Возвращаемое значение (Return value)

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