gnutls_privkey_sign_data3
Api function
Usage
#include <gnutls/abstract.h>
int gnutls_privkey_sign_data(gnutls_privkey_t signer, gnutls_digest_algorithm_t hash, unsigned int flags, const gnutls_datum_t * data, gnutls_datum_t * signature);
Arguments
gnutls_privkey_t signer
|
Holds the key |
|---|---|
gnutls_digest_algorithm_t hash
|
should be a digest algorithm |
unsigned int flags
|
Zero or one of |
const gnutls_datum_t * data
|
holds the data to be signed |
gnutls_datum_t * signature
|
will contain the signature allocated with |
Overview
This function will sign the given data using a signature algorithm supported by the private key. Signature algorithms are always used together with a hash functions. Different hash functions may be used for the RSA algorithm, but only the SHA family for the DSA keys.
You may use gnutls_pubkey_get_preferred_hash_algorithm() to determine the hash algorithm.
Returns
On success, GNUTLS_E_SUCCESS (0) is returned, otherwise a negative error value.
