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.
