Re PGP, check out the PGPi (I think it was called) version. During a period, they exported it on paper and then scanned it in europe, because exporting a book was ok even if printed in only one copy but exporting encryption code was not ;-). This was not a weakened version, but I really don’t remember exactly what years this was.
If you’re interested to hire someone to build something, send me a PM. I don’t think I have any media left from that time, but it appears it might be possible run Windows 3.x in Virtualbox or VMWare. It ought to be possible to get hold of a Turbo C copy somehow also.
