Not like I have the time or anything, but is there any value in attempting something like "bruterc2"? (IANARC (I am not a real cryptographer), but it looks like one trick to that would be to somehow short-circuit the key setup stage. I suppose you could just start after it's mapped the user key into the "xkey" array, but I might be missing something.) ______c_____________________________________________________________________ Mike M Nally * Tivoli Systems * Austin TX * I want more, I want more, m5@tivoli.com * m101@io.com * I want more, I want more ... <URL:http://www.io.com/~m101> *_______________________________
