Gentlemen, It was recently mentioned on this list that there were additional restrictions placed on the use of ciphers by private citizens during World War II. I'm curious if anyone knows of a good resource for further information on this topic. (Now, inevitably, Choate is going to sent me a Google URL. This is fine, since I wasn't able to get Google to give me anything but information on documents discussing recent export restrictions, happening to mention WWII.) Thank you. -MW-
