I actually found an open-source tool, 7-zip, that includes AES-256 encryption functionality. For whatever reason, it runs several times faster than GnuPG in software. Fast enough, in fact, that the removable hard disk devices have become the limiting factor in the system (the 7-zip process only uses 70% CPU on a 2.4 GHz P4). The code is open-source, and it uses a salted + iterated SHA256 hash to produce the AES key from a pass phrase. The AES implementation is Gladman's well-known and fast C++ code. Looking at the source, I haven't figured out whether it uses ECB or CFB mode yet; the 7-zip code is rather light on comments. I am assuming ECB, which should be fine for my application. See http://www.7-zip.org for more details. Thanks for all the help. -- Ryan ========================= All problems can be solved by diplomacy, but violence and treachery are equally effective, and more fun. -Anonymous _______________________________________________ Gnupg-users mailing list Gnupg-users@gnupg.org http://lists.gnupg.org/mailman/listinfo/gnupg-users
