gnutls_privkey_derive_secret − API function
#include <gnutls/abstract.h>
int gnutls_privkey_derive_secret(gnutls_privkey_t privkey, gnutls_pubkey_t pubkey, const gnutls_datum_t * nonce, gnutls_datum_t * secret, unsigned int flags);
gnutls_privkey_t privkey
a private key of type gnutls_privkey_t
gnutls_pubkey_t pubkey
a public key of type gnutls_pubkey_t
const gnutls_datum_t * nonce
an optional nonce value
gnutls_datum_t * secret
where shared secret will be stored
unsigned int flags
must be zero
This function
will calculate a shared secret from our privkey and
peer’s pubkey . The result will be stored in
secret , whose data member should be freed after use
using gnutls_free(). privkey and
pubkey must be backed by the X.509 keys.
On success, GNUTLS_E_SUCCESS (0) is returned, otherwise a negative error value.
