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 sup- ported 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 SHA-1 for the DSA keys.

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

SINCE 2.12.0
