NAME        top

       gnutls_privkey_sign_data2 - API function

SYNOPSIS        top

#include <gnutls/abstract.h>int gnutls_privkey_sign_data2(gnutls_privkey_tsigner,gnutls_sign_algorithm_talgo, unsigned intflags, constgnutls_datum_t *data, gnutls_datum_t *signature);

ARGUMENTS        top

       gnutls_privkey_t signer                   Holds the key       gnutls_sign_algorithm_t algo                   The signature algorithm used       unsigned int flags                   Zero or one ofgnutls_privkey_flags_t       const gnutls_datum_t * data                   holds the data to be signed       gnutls_datum_t * signature                   will contain the signature allocated withgnutls_malloc()

DESCRIPTION        top

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

RETURNS        top

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

SINCE        top

       3.6.0
