Does anyone know the status of public key patents in Canada? I had
heard that RSA was patented only in the USA, but I don't know about
the others.

If only US patent protection exists for public key cryptography, then
the obvious thing to do with rpem is to put it up for anonymous FTP on
a site in Canada, beyond the protection of the US patent.  Of course,
individual US users who retrieve and use it in the US could still be
sued for patent infringement, but this would be a lot harder than
going after a public FTP site (as demonstrated by the nonsense over
R/X-rated GIF images).

And since Canada is an exception to the State Department requirements
for licensing the export of cryptographic software, there should be
no problem on this score.
