NAME¶

gnutls_privkey_sign_data2 - API function

SYNOPSIS¶

#include <gnutls/abstract.h>

int gnutls_privkey_sign_data2(gnutls_privkey_t signer, gnutls_sign_algorithm_t algo, unsigned int flags, const gnutls_datum_t * data, gnutls_datum_t * signature);

ARGUMENTS¶

gnutls_privkey_t signer

Holds the key

gnutls_sign_algorithm_t algo

The signature algorithm used

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()

DESCRIPTION¶

This function will sign the given data using the specified signature algorithm. This function is an enhancement of gnutls_privkey_sign_data(), as it allows utilizing a alternative signature algorithm where possible (e.g, use an RSA key with RSA-PSS).

RETURNS¶

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

SINCE¶

3.6.0
