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
