- 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.
