Thank you. That is more than I need for my present purposes.

I had forgotten about your sending me the GMP examples earlier, since
at that time I was looking for something that was interpreted.

But now I am after some compiled object code for which the source code
is not publically available; sort of the object code equivalent of Adam
Back's RSA in 2 lines of Perl. I don't need to produce anything that
anyone would actually use; just some strong crypto in object code
to illustrate a legal argument about the encryption export regulations.
