Looks like the stalling tactics have begun. I just got a phone call from "Susan Shea" from the National Security Agency. She said that to "make a better determination" she would need a copy of the diskette. I explained (as I had in my written request) that the diskette in question contained exactly the same source code as was printed in Part 5 of the book Applied Cryptography, byte for byte. But she claimed that as she did not have a copy of that, she would still need the diskette. Right. The NSA doesn't have a copy of Applied Cryptography, and has never seen one. Yet, apparently, they signed off on my original CJ request to export the printed book (the State letter mentions comments from the Department of Defense, which is always a code phrase for the NSA in such situations). Sigh. I will send it off to them. This should buy them about two days, unless I get really extravagant and switch from Priority Mail to Express Mail... Phil PS. Does anybody consider it odd that someone from the NSA would actually identify themselves as such?
