gnutls_x509_privkey_sign_hash - Man Page

API function


#include <gnutls/compat.h>

int gnutls_x509_privkey_sign_hash(gnutls_x509_privkey_t key, const gnutls_datum_t * hash, gnutls_datum_t * signature);


gnutls_x509_privkey_t key

a key

const gnutls_datum_t * hash

holds the data to be signed

gnutls_datum_t * signature

will contain newly allocated signature


This function will sign the given hash using the private key. Do not use this function directly unless you know what it is. Typical signing requires the data to be hashed and stored in special formats  (e.g. BER Digest-Info for RSA).

This API is provided only for backwards compatibility, and thus restricted to RSA, DSA and ECDSA key types. For other key types please use gnutls_privkey_sign_hash() and gnutls_privkey_sign_data().


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

Deprecated in: 2.12.0
