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

stuff, so you read and act on it at your own risk. This is just my best
effort to comply with the law without sacrificing my right to publish.

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.

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. Please let me know if I mangled it
in the process...
