DVD Jon has cracked the digital rights management (DRM) protection features that protect legitimately-purchased iTunes music for GNU/Linux computers, The Register reports.

As reported, the programmer first cracked the DRM in November, releasing code that took the streaming audio from a protected track in raw AAC format. At the time it was a non-trivial exercise to transform the results into a playable track. DVD Jon has worked to rectify this, and has released code to make it possible.

The Norwegian government recently ceased its long-standing case against DVD Jon, who broke the encryption software that protected – and localized – DVDs, solely in order that he could play legitimately acquired DVDs using his Linux computer, he claimed.
