gnutls_privkey_sign_data – API function

Synopsis

#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 gnutls_privkey_flags_t
const gnutls_datum_t * data: holds the data to be signed
gnutls_datum_t * signature: will contain the signature allocate with gnutls_malloc()

Description

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.

Since

2.12.0
