Vanguard's posting about a friend of his in the Air Force telling him some things about Air Force crypto devices may be of some theoretical interest, but posting it here really gets me majorly uncomfortable. Current military crypto practices are probably very highly guarded secrets. Posting that kind of thing, even in a general way, could be very dangerous; if not to national security then at least to ours. I'd like to ask we have a general agreement to not post things which may be classified. No point giving the govt a good excuse to stop our R&D projects cold. -gg
