Has anyone implemented a simple anonymous chat system (an anonymous irc) using the technique described in Applied Cryptography 2nd edition? I'm speaking of the Anonymous Message Broadcast documented in section 6.3, it begins on page 137. Can the same system be implemented using base256 (unsigned char, 8bit ASCII) instead of the simple on/off binary method that is described in the explanation? How would it differ. Thanks. (define(RSA m e n)(list->string(u(r(s(string->list m))e n))))(define(u a)(if(> a 0)(cons(integer->char(modulo a 256))(u(quotient a 256)))'()))(define(s a)(if (null? a)0(+(char->integer(car a))(* 256(s(cdr a))))))(define(r a x n)(cond((= 0 x)1)((even? x)(modulo(expt(r a(/ x 2)n)2)n))(#t(modulo(* a(r a(1- x)n))n))))
