gnutls_privkey_sign_data - API function
#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);
gnutls_privkey_t signer
Holds the key
gnutls_digest_algorithm_t hash
should be a digest algorithm
unsigned int flags
Zero or one of gnutls_privkey_flags_t
const gnutls_datum_t * data
holds the data to be signed
gnutls_datum_t * signature
will contain the signature allocated with gnutls_malloc()
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.
On success, GNUTLS_E_SUCCESS (0) is returned, otherwise a negative
error value.
