Digital rights management circumvention software
QTFairUse
QTFairUse is a software application first released in November 2003 by Jon Lech Johansen. It dumps the raw output of a QuickTime AAC stream to a file, which could bypass the digital rights management (DRM) algorithm called FairPlay used to encrypt music content of media files such as those distributed by the iTunes Store, Apple's online music store. Although these resulting raw AAC files were unplayable by most media players at the time of release, they represented the first attempt at circumventing Apple's encryption. These early versions of QTFairUse would save only the "raw" AAC (not contained in an MPEG-4 (MP4) container), but later incarnations properly supported full conversions. Released under the terms of the GNU General Public License, QTFairUse is free software. (Wikipedia).
