gnutls_x509_privkey_sign_data - sign data using the private key
SYNOPSIS
#include <gnutls/x509.h>
int gnutls_x509_privkey_sign_data(gnutls_x509_privkey_t key, gnutls_digest_algorithm_t digest, unsigned int flags, const gnutls_datum_t *
data, void * signature, size_t * signature_size);
ARGUMENTS
gnutls_x509_privkey_t key
Holds the key
gnutls_digest_algorithm_t digest
should be MD5 or SHA1
unsigned int flags
should be 0 for now
const gnutls_datum_t * data
holds the data to be signed
void * signature
will contain the signature
size_t * signature_size
holds the size of signature (and will be replaced by the new size)
DESCRIPTION
This function will sign the given data using a signature algorithm supported by the private key. Signature algorithms are always used
together with a hash functions. Different hash functions may be used for the RSA algorithm, but only SHA-1 for the DSA keys.
If the buffer provided is not long enough to hold the output, then *signature_size is updated and GNUTLS_E_SHORT_MEMORY_BUFFER will be
returned.
RETURNS
On success, GNUTLS_E_SUCCESS is returned, otherwise a negative error value.

gnutls_openpgp_privkey_sign_hash - sign the given data using the private key params
SYNOPSIS
#include <gnutls/openpgp.h>
int gnutls_openpgp_privkey_sign_hash(gnutls_openpgp_privkey_t key, const gnutls_datum_t * hash, gnutls_datum_t * signature);
ARGUMENTS
gnutls_openpgp_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. You should use gnutls_openpgp_privkey_set_subkey() before calling this func-
tion to set the subkey to use.
RETURNS
On success, GNUTLS_E_SUCCESS is returned, otherwise a negative error value.
