Getting real entropy from mouse movements under X may be tricky, because the X server goes out of its way to compress mouse movement reporting and to buffer events sent to the client ("X is an exercise in avoiding system calls"). You'll probably get less entropy than you might think.
Also add that many people seem to tend to swirl the mouse in fast circles, where there isn't *any* latency between mouse movements, and you get even less entropy. I suspect that Colin Plumb's code, while a nice try, would be a bit less useful that might have been otherwise suspected. - -- Ed Carp, N7EKG Ed.Carp@linux.org, ecarp@netcom.com 214/993-3935 voicemail/pager Finger ecarp@netcom.com for PGP 2.5 public key an88744@anon.penet.fi Q.
