'''QTFairUse''' is a ] first released in November 2003 by ]. It dumps the raw output of a QuickTime AAC stream to a file, which could bypass the ] (DRM) ] called ] used to ] music content of media files such as those distributed by the ], ] ]. Although these resulting raw ] 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 ] (MP4) ]), but later incarnations properly supported full conversions. |

==Technical approach== |
|
|
Functionally, the purpose of QTFairUse is to convert protected audio files (.m4p extension) purchased from Apple's iTunes Store into M4a files, without DRM. To accomplish this task it uses a rather uncommon approach: instead of removing the already present DRM, it waits for iTunes to play back the protected file and intercepts the unencrypted AAC data stream as it is sent to the ]. During this process, it copies unencrypted data, frame-by-frame, into ] and then inserts it into a new MP4 container that is free of any DRM. |

==iTunes versions== |
|
|
The current release (as of December 13, 2007) of QTFairUse6, version 6-2.5, supports ] 6.0.2 through 7.0.2. An updated config file compatible with iTunes 7.1.2 was released on May 14, 2007. An iTunes 7.3.1 compatible configuration file was released on June 12, the same day Apple released the new iTunes update. An iTunes 7.4.2.4 compatible configuration file was released on September 18, 2007.<ref>{{cite web| url=http://hymn-project.org/forums/viewtopic.php?t=1553| title=hymn:: View Topic - QTFairUse6| publisher=Igor Skochinsky & Hymn Project| access-date=2007-08-09}}</ref> This config file is also compatible with iTunes 7.5.0.20. The config file needs to be updated with each new iTunes release; so far the author has released updates the same day as the new iTunes release. As of January 15, 2008, the author has not updated QTFairUse for the latest version of iTunes, and the current revision is not compatible with that version. |
