gnutls_privkey_sign_data2(3)

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
