Note that the DES algorithm has been published for years. See at "Cryptography and Data Security", Dorothy Denning, Addison-Wesley, 1982. I'm sure there's also an NBS document describing it for sale by the US Government. It's hard to believe that posting C source on UseNet is subtantially different from that. You'd have a hard time defining the difference between an algorithm described by mathematical pseudo-code and C source that just also happens to run on a computer. Of course the NSA reads this newsgroup. But don't expect them to react to it, much. A big part of the business of keeping secrets is not letting other people know what you know. The more they react, the more we'll know about what they worry about. So they'll stay quietly in the background. Just to prove it, here's the source for a DES cracker: ZZZZ 0345 NOTICE 490 LINES REMOVED TO CLASSIFIED FILE DRAWER NBS-D-5712 CONTACT ARMY INFORMATION OFFICE, FT MEAD, MARYLAND. See? ;-) Michael L.
