gnutls_privkey_sign_data(3)

NAME
gnutls_privkey_sign_data - API function

SYNOPSIS
#include <gnutls/gnutls.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
    should be 0 for now

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. Use gnutls_pubkey_get_preferred_hash_algorithm() to determine the hash algorithm.

RETURNS
On success, GNUTLS_E_SUCCESS is returned, otherwise a negative error value.

SINCE
2.12.0
