NO. "Prior to the advent of personal computers and strong cryptography," even simple codes (from today's point of view) were de facto unbreak- able. A combination of a few of the 'cryptographic procedures' which we used as kids and which have been around for centuries was enough to make it impossible to decrypt a message: Without computers, even a bunch of experts would have had a hard time to crack such a silly cypher (unless they had sufficient plain/crypt text pairs etc.). I'm sure many criminal offenders who encrypted their secret messages using such a system got away unpunished because no ingenious master mind such as Sherlock Holmes or Hercule Poirot happened to find out the keys and algorithms by mere intuition. Today a lot of attacks to all known cryptosystems can be done with minimum resources within a few hours. Bad luck for the kids who want to hide something from their mathematically skilled parents ... But at the same time there are better algorithms around, and again the experts have a hard time cracking them. Why should this suddenly be a problem? Why do you want special legislation right now? Just wondering. -- Detlef Lannert DC3EK E-Mail: tsos@rz.uni-duesseldorf.de "Gedanken sind nicht stets parat, man schreibt auch, wenn man keine hat." Wilhelm Busch
