gnutls_privkey_sign_raw_data (3)

#include <gnutls/compat.h>

int gnutls_privkey_sign_raw_data(gnutls_privkey_t key, unsigned flags, const gnutls_datum_t * data, gnutls_datum_t * signature);

gnutls_privkey_t key

Holds the key

unsigned flags

should be zero

const gnutls_datum_t * data

holds the data to be signed

gnutls_datum_t * signature

will contain the signature allocate with gnutls_malloc()

This function will sign the given data using a signature algorithm supported by the private key. Note that this is a low-level function and does not apply any preprocessing or hash on the signed data. For example on an RSA key the input data should be of the DigestInfo PKCS 1 1.5 format. Use it only if you know what are you doing.

Note this function is equivalent to using the GNUTLS_PRIVKEY_SIGN_FLAG_TLS1_RSA flag with gnutls_privkey_sign_hash().

On success, GNUTLS_E_SUCCESS (0) is returned, otherwise a negative error value.
