128-bit symmetric key should be sufficient. (Wassenaar
posed a 56-bit limit. I am not very clear of its
applicability, though.) But your last sentence seems
to imply that you would get troubles in freely publishing
crypto codes on the internet (webpages, posts to groups)
much like the situation previously in US. Is that right?
