Dear Bruce, I was testing the Raike's Public Key software, when I remembered a section of your excellent book. In Applied Cryptography, second edition, section 19.10 (page 482) you present the Renji's work about a public key algorithme based on finite automata. Where could we found the FAPKC1 and FAPKC2 algorithms, their implementations, and executable versions (you mention an Intel486 test). Many thanks, With kindest regards Jean-Paul ~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~- Jean-Paul et Micheline Kroepfli (our son: Nicolas and daughter: Celine) eMail: JeanPaul.Kroepfli@utopia.fnet.fr Also Compuserve and MSNetwork Phone: +33 81 55 52 59 (F) PostMail: F-25640 Breconchaux (France) or: +41 21 843 27 36 (CH) or: CP 138, CH-1337 Vallorbe Fax: +33 81 55 52 62 (Switzerland) Zephyr(r) : InterNet Communication and Commerce, Security and Cryptography consulting PGP Fingerprint : 19 FB 67 EA 20 70 53 89 AF B2 5C 7F 02 1F CA 8F "The InterNet is the most open standard since air for breathing"
