In regards to implementing triple DES, is it just simply a matter of encrypting with DES three times, like: E(K1,E(K2,E(K3,x))) ??? Anyone have a particular recommended (or _not_ recommended) flavor or "mode of operation": ??? 1. E(K1,E(K2,E(K3,x))) 2. E(K1,D(K2,E(K3,x))) 3. E(K1,D(K2,E(K1,x))) 4. E(K1, Tran( E(K2, Tran( E(K3, Compress( x )))))) 5. E(K1, Prngxor(K4, Tran( E(K2, Tran( Prngxor(K5, E(K3, Compress( x )))))))) ________________________________________________________________________ Get Your Private, Free E-mail from MSN Hotmail at http://www.hotmail.com
