What form RC4 distribution have?
(I have read the whole thread) I think we need four things. 1) void srandom(int arg) which uses the argument to seed. 2) void srandomdev(void) which uses system entropy to seed. 3) int random(void) which returns a number statistically random in all bits. 4) <something else> which returns as many bytes of randomness (statistically random in all bits) as the caller asks for. We have most of this, and RC4 can deliver. RC4's "licence" is fine. Call it "ArCFour" and there is no problem. The code is small, fast and repeatable, and meets conditions 1-4 above. Coding is Junior-high-school level, given the spec. M -- Mark Murray iumop ap!sdn w,I idlaH To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-current" in the body of the message
