Z:gnu-www-ja-kragen-software--a2af5b-Another tack is to lock inform/en

Another tack is to lock information up in things. The NSA 's Skipjack algorithm was classified for several years; implementations were widely available, but only in special hardened devices. This allowed them to deploy it widely behind the iron curtain that surrounds classified research, and they intended to deploy it widely in the outside world, too. (So far, I'm outside that curtain.) Recently, circumstances forced them to distribute software implementations of Skipjack, and so they declassified it. (See http://www.schneier.com/crypto-gram-9807.html#skip for more.)
