We had a mini-debate about this with rayiner in another thread pointing out that people have always been allowed to use cryptography in America and have always done so, and that it&#x27;s often made it harder and occasionally impossible for the government to figure stuff out. It&#x27;s true that it was always a very deliberate decision and effort in the past, rather than something particularly convenient or automatic, but people have had ciphers for centuries, and some of those have been successful at obscuring communications from governments, and in the U.S. there was no apparent suggestion that this was legally improper.
