*Groan* One would think that anybody who would go to the expense of designing an encrypting FAX machine could at least afford to read the introduction to any beginning crypto book. Heck, I bet it's even the generator on page 46 of K&R's second edition C book. b& -- Ben.Goren@asu.edu, Arizona State University School of Music net.proselytizing (write for info): Protect your privacy; oppose Clipper.

I just said this last week. PNRG-XOR can be very secure. If they're using Blum-Blum-Shub, it could be secure, since there are other things to go wrong. If they're using a LFSR, it's not secure.
