Thanks, Harry. Interesting page, but I don't think primes on the order of 3 and 11 really qualify as secure, which was pretty much what I figured would be the case: anything that can reasonably be done by hand wouldn't be secure. Oh well. Pad locks it is. =) - -Brian - -- Feel free to contact me using PGP Encryption: Key Id: 0x3AA70848 Available from: http://keys.gnupg.net -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.9 (MingW32) iQEcBAEBAgAGBQJKcaBhAAoJEHOUulIkSI7cauYH/0aKd4ytkq7Fq5jxemSREbsg laK1AmG28cNi+JDUxdshMsVfz7QjBw9WmENq9VvcaxkHRynN05hT3f7z4upnbSfq EbLyqDZJsn2B5iTFJt008+09GMiZBUCnwDrh5MQpxeWWKxdM0NXuJZRmCIpMCzZ6 wZUxpZ1ce7Yx1PsdpVtq5XwFBvFweF9qAwoXl7tWpdUwD03SmrO/ntv/WMLc3cNE 2ZQzkPhmufG8XhYxSeQ+72ftD1dSKKWlYjqCic8va9J6mWsw6wEGJjZ5bLXdP9c+ kzrCiKJPjlaJzScrC5NdzfDoGXVCvIQDxG7W9ZbWFgtxPpTCI6PHwFiK79Im1kw= =otX/ -----END PGP SIGNATURE----- _______________________________________________ Gnupg-users mailing list Gnupg-users@gnupg.org http://lists.gnupg.org/mailman/listinfo/gnupg-users
