Redshirt was used in the Uplink (video game)[1] to bring challenges towards players who are curious in nature. The featured game itself is about computer hacking, so the pseudo encryption was used to encrypt save games for instance to prevent players cheating the game[2], or by encrypting portions of game assets to cater for easter eggs, like the game bible series that were distributed on separate discs[3] or shared on peer-to-peer file sharing software like Kazaa.[4]
Earlier versions of Redshirt uses simple XOR encryption scheme[5] Latter revisions incorporated features like one-time-pad (OTP) encryption[6]. Certain revisions of redshirt2 used a different technique.[7]
