- This can't be the case. I can travel to Europe, learn about IDEA, then
- come to the US and hold a public speech on how the algorithm works. In
- order to prohibit the "importation of cryptographic algorithms", as
- opposed to cryptographic implementations, it would be necessary to
- forever ban anyone who learned about any cryptographic system abroad
- from ever reentering the US because having legitimately learned of the
- system abroad no US law could prevent him from describing the system
- to others, given that the first amendment would prohibit such a
- restraint on speech.
-
- It is, in fact, impossible to prohibit the export of unclassified
- cryptographic algorithms (but not unclassified cryptographic software)
- for exactly the same reason -- it would be necessary to prohibit
- anyone who had ever read the DES specs, say, from leaving the US
- without a license.
-
- As we all know that the distinction between an algorithm and an
- implementation in actual software is just a matter of effort that
- educated programmers around the world can readily accomplish, it is
- easily seen why the entire notion of export/import controls on
- cryptography is idiotic. However, idiocy has never stopped the
- government in the past, so there is little expectation it will stop it
- in the future.
