From f3cd7f50dea0bfc9806322eeacfae6b19a350272 Mon Sep 17 00:00:00 2001 From: Reto Buerki Date: Tue, 24 Jul 2012 10:40:26 +0200 Subject: Add initial TKM Diffie-Hellman implementation The tkm_diffie_hellman_t plugin acquires a DH context from the Trusted Key Manager and uses it to get a DH public value and the calculated shared secret. Proper context handling is still missing though, the plugin currently uses context ID 1. The get_shared_secret function will be removed as soon as the TKM specific keymat is ready. --- src/charon-tkm/tests/diffie_hellman_tests.c | 58 +++++++++++++++++++++++++++++ 1 file changed, 58 insertions(+) create mode 100644 src/charon-tkm/tests/diffie_hellman_tests.c (limited to 'src/charon-tkm/tests/diffie_hellman_tests.c') diff --git a/src/charon-tkm/tests/diffie_hellman_tests.c b/src/charon-tkm/tests/diffie_hellman_tests.c new file mode 100644 index 000000000..c2e905e76 --- /dev/null +++ b/src/charon-tkm/tests/diffie_hellman_tests.c @@ -0,0 +1,58 @@ +/* + * Copyright (C) 2012 Reto Buerki + * Copyright (C) 2012 Adrian-Ken Rueegsegger + * Hochschule fuer Technik Rapperswil + * + * This program is free software; you can redistribute it and/or modify it + * under the terms of the GNU General Public License as published by the + * Free Software Foundation; either version 2 of the License, or (at your + * option) any later version.
