There have been comments on the rc5 list to the effect DES doesn't lend itself to the PPro and optimization. Also the Bovine effort has had much less time thinking about and improving their DES code than the RC5 code. Heck, they still don't have a MacOS PowerPC client for DES-II. -- David Kelly N4HHE, dkelly@nospam.hiwaay.net ===================================================================== The human mind ordinarily operates at only ten percent of its capacity -- the rest is overhead for the operating system.
