Greetings, all. I'm trying to get a handle on US law regarding sharing of crypto with foreign nationals. Let's say I'm a US citizen residing in the US, have an interest in strong crypto, and have an acquaintance who is a foreign national. How much access can I give my friend to my computer and my home office? I've identified a few dimensions to create scenarios, and a few points on each dimension. - An allied nation, eg Canada - A friendly or neutral nation, eg Finland - An awkward nation, eg PRC - A hostile nation, eg Libya - A friend who comes by to use my computer on occasion - A roommate who uses my computer regularly - A girlfriend who sometimes uses my computer - A live-in girlfriend - A new spouse who plans to become a US citizen but is currently a foreign national - I have install disks for the domestic-only versions of commercial apps such as Netscape Communicator - I have PGP or GPG installed and configured but it does not automatically run for email - PGP/GPG is always available for email or from the Windows Explorer - I have the source code for strong crypto in electronic form - I have source code for strong crypto in treeware - I have articles and books discussing crypto, possibly with code snippets, in printed or electronic form - I develop strong crypto, and have code, working papers, and the like available in printed and electronic form - I am helping my friend become a more proficient computer user by showing the use of "user" apps, which may have built-in strong crypto - My friend is already a proficient user and can encrypt or sign a document or mail message - I am helping my friend become a more proficient programmer and he or she has an interest in crypto - My friend is already a proficient programmer and can implement strong crypto Now, since answers to all of the cases is a bit much to ask, here's one scenario of particulerest to me: A girlfriend from the PRC; she's a new programmer and I'm working with her on improving her skills; I have _Applied Cryptography_ on the shelf, source code on my computer, and PGP installed. Thankee Kindly, Steve Furlong
