lossless DRM removal software for Apple iTunes

 

Jon Johansen, a.k.a. DVDJon, known for cracking CSS (Content Scrambling System) DRM used on DVDs, discovered multiple methods for removing encryption from Apple iTunes FairPlay DRM-protected files while working to build an iTunes client for Linux:

• The first one, QTFairUse - grabbs song data after it is unlocked and uncompressed by iTunes, and then dumps the raw stream into a large container file, requiring further processing afterward.
  
• The second, written by Johansen for the open source VLC media player - and reused in PlayFair, Hymn, JHymn and other derivatives - intercepts unlocked but not yet uncompressed song files, creating a small, ready to play, unencrypted AAC file.
  
• PyMusique - a Linux client for the iTunes Store, pretends to be iTunes. It requested songs from Apple's servers and then downloaded the purchased songs without locking them, as iTunes would.
  
• FairKeys - pretends to be iTunes; it requests a user's keys from Apple's servers and then uses these keys to unlock existing purchased songs.

More DRM removal software for iTunes:

• Requiem - decrypts .m4p files. It doesn't use any Apple libraries - it is a complete reverse engineering of Apple's DRM scheme.

And you can always burn .m4p files bought in iTunes to a CD and rip the from the CD. This is not a lossless method unless you rip your CD to lossless FLAC, Monkey Audio,... which is a waste of hard disk space.
