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