Sure. That also implies the importance of S-box quality assessment. My approach was to generate a random S-box and let the user change it if it performs badly. But that's a sort of responsibility shift. It's time for me to learn a bit more about S-box design and verify that the specific S-box has no obvious defects at least. :-) -- WBRBW, Leonid Evdokimov, https://darkk.net.ru tel:+79816800702 PGP: 6691 DE6B 4CCD C1C1 76A0 0D4A E1F2 A980 7F50 FAB2
