Your answer implies that you are looking for something that you would actually use, rather than just a pen-and-paper demo for instruction purposes. In this case, whilst it's not exactly "public key cryptography", even the simplest algorithms are cryptographically secure with a one-time pad. Of course, you then have the key exchange problem. -- David Smith | Tel: +44 (0)1454 462380 Home: +44 (0)1454 616963 STMicroelectronics | Fax: +44 (0)1454 462305 Mobile: +44 (0)7932 642724 1000 Aztec West | TINA: 065 2380 GPG Key: 0xF13192F2 Almondsbury | Work Email: [email protected] BRISTOL, BS32 4SQ | Home Email: [email protected] _______________________________________________ Gnupg-users mailing list [email protected] http://lists.gnupg.org/mailman/listinfo/gnupg-users
