gnutls_dh_get_group − API function


, gnutls_datum_t * int gnutls_dh_get_group(gnutls_session_t

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.
