> ... (It IS a federal law that > no cipher may be used for international traffic that NSA can't break... I know of no such law. However, I've read of a ruling which may (or may not) have a similar impact in practice if not in theory. That is, the Export Control regulations prohibit export of cryptographic equipment with a key length greater than >64 bits, but permit such export if the key length is less than 48 bits. This was pointed out during the debate over whether or not NSA sandbagged DES, since the key length was reduced to 56 bits from the original 112.
