int gnutls_x509_privkey_sign_hash(gnutls_x509_privkey_t key, const gnutls_datum_t * hash, gnutls_datum_t * signature);
ARGUMENTS
gnutls_x509_privkey_t key
Holds the key
const gnutls_datum_t * hash
holds the data to be signed
gnutls_datum_t * signature
will contain newly allocated signature
DESCRIPTION
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).
RETURNS
On success, GNUTLS_E_SUCCESS is returned, otherwise a
negative error value.
