gnutls_dh_get_group − API function
#include <gnutls/gnutls.h>
int gnutls_dh_get_group(gnutls_session_t session, gnutls_datum_t * raw_gen, gnutls_datum_t * raw_prime);
gnutls_session_t session
is a gnutls session
gnutls_datum_t * raw_gen
will hold the generator.
gnutls_datum_t * raw_prime
will hold the prime.
This function will return the group parameters used in the last Diffie−Hellman key exchange with the peer. These are the prime and the generator used. This function should be used for both anonymous and ephemeral Diffie−Hellman. The output parameters must be freed with gnutls_free().
Note, that the prime and generator are exported as non−negative integers and may include a leading zero byte.
On success, GNUTLS_E_SUCCESS (0) is returned, otherwise an error code is returned.
