Can you tell more of this? There is an Windows disk encryption utility called Teamware Crypto that uses FEAL-8. This program is quite popular in Europe, distributed and made by ICL Data.
The attacks on FEAL are pretty lengthy. _Applied Cryptography_ 2nd edition by Bruce Schneier has a list of attacks on page 311. The Shamir attack is not the one to worry about. Matsui and Yamagishi have an attack that breaks it in 2^15 known plaintexts.
I have the book but unfortunately I gave it to a friend for some time to read it :) Anyway I personally use F-Secure Desktop which uses Blowfish and I am happy with that. Just that I thought the product Teamware Crypto is not as secure as the marketing materials say. Jüri Kaljundi AS Stallion jk@stallion.ee WWW ja andmeturva teenused http://www.stallion.ee/
