You should check the exact text yourself, but the way I read the EAR, you are not "exporting" strong cryptographic software without a license (exept to Canada, which needs no license) if you do things "such as" (1) have the guests to your site acknowledge that the EAR restricts export, (2) have the guests affirm that they can legally get the software (proper citizenship or residency & location), and (3) "check the address of the destination computer to see if it is in the USA" or Canada. The last one, I interpret rather loosely to mean that if the guest's email address domain isn't one commonly used in the USA or Canada, then I deny access. We all know that not all .com addresses are North American, but chances are really good that if the address ends in .ru, then the destination machine is probably not in North America. This is not a perfect way to prevent export, of course, but it is what the regulations say, as I read them. For a pointer to the regulations and to my access request form and crypto site, see http://www.sni.net/~mpj/crypto.htm Disclaimer: I am not a lawyer, and most lawyers don't even understand this stuff, so you read and act on it at your own risk.

download at the web page below. On my web page, I have some stuff in bold print that informs about the ITAR and tells people to go away if they're not from the US or Canada. Does this count as an unrestricted FTP site?

Is there any reason why people have to look at your warning before reading your warning? At my site, the ftp site itself is in a hidden directory that changes names often enough that people can't successfully link to the restricted files for very long without going through my warning page. Indeed, my site can't be navigated and indexed properly by web search robots. At your site, it is extremely likely that someone would find your software without ever seeing your warning. Indeed, your software is on another server with another interface. I think that your site counts as unrestricted.

Also, back to the question of registration numbers. A registration number is just a string of letters and numbers, and is essentially the same as a friendly letter; it contains no cryptographic code. For all anyone knows, I could just be charging for pseudo-random numbers, again, nothing of cryptographic significance. Is it illegal for me to mail someone outside of the US or Canada a registration code? Thanks for any help.

The registration code is legally equivalent to the registered software that it unlocks. Sending the registration code to France, for example, would be likely to be considered the same as sending the registered software to France (in violation of the laws of both countries). Now if the "unregistered" software is weak (i. e. crippled key length) without the registration code, you need not worry about posting it publicly and without restriction, as long as you don't export the registration code (except to Canada) without a license. I do this with Quicrypt (ftp://ftp.csn.net/mpj/qcrypt11.zip). BTW, I posted krem104.zip at my site.
