@deftypefun {int} {gnutls_x509_privkey_sign_hash} (gnutls_x509_privkey_t @var{key}, const gnutls_datum_t * @var{hash}, gnutls_datum_t * @var{signature})
@var{key}: a key

@var{hash}: holds the data to be signed

@var{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).

@strong{Returns:} On success, @code{GNUTLS_E_SUCCESS}  (0) is returned, otherwise a
negative error value.

Deprecated in: 2.12.0
