Editing Jon Lech Johansen (section)

===2005===
On March 18, 2005, Travis Watkins and Cody Brocious, along with Johansen, wrote [[PyMusique]], a [[Python (programming language)|Python]] based program which allows the download of purchased files from the iTunes Music Store without DRM encryption.<ref>Smith, Tony (March 18, 2005) &ndash; [https://www.theregister.co.uk/2005/03/18/itunes_pymusique/ "DVD Jon: buy DRM-less tracks from Apple iTunes"]</ref> This was possible because Apple Computer's iTunes software adds the DRM to the music file after the music file is downloaded. On March 22, Apple released a [[Patch (computing)|patch]] for the iTunes Music Store blocking the use of his PyMusique program. The same day, an update to PyMusique was released, circumventing the new patch.

On June 26, 2005, Johansen created a modification of Google's new in-browser video player (which was based on the open source VLC media player) less than 24 hours after its release, to allow the user to play videos that are not hosted on Google's servers.

In late 2005, [[Håkon Wium Lie]], the Norwegian CTO of [[Opera Software]], co-creator of Cascading Style Sheets and long-time supporter of open source, named Johansen a "hero" in a net meeting arranged by one of Norway's biggest newspapers.<ref>{{cite news | url=http://www.dagbladet.no/kultur/2005/05/10/431391.html | title=DVD-Jon er en helt | first=Lars Eirik | last=Eide | newspaper =Dagbladet | language=no | date=2005-05-10 | access-date=2007-08-14}}</ref> On September 2, 2005, ''The Register'' published news that DVD Jon had defeated encryption in Microsoft's Windows Media Player by reverse engineering a proprietary algorithm that was ostensibly used to protect [[Windows Media Station]] NSC files from engineers sniffing for the files' source IP address, port or stream format. Johansen had also made a decoder available.<ref>{{cite news | url=http://nanocr.eu/2005/08/31/reversing-nsc/ | title=Reversing NSC | publisher=nanocr.eu | first=Jon Lech | last=Johansen | date=2005-08-31 | access-date=2007-08-14}}</ref><ref>Clarke, Gavin (San Francisco.

In September 2005, Johansen announced the release of SharpMusique 1.0, an alternative to the default iTunes program. The program allows Linux and Windows users to buy songs from the iTunes music store without copy protection. In 2005, Johansen worked for MP3tunes in San Diego as a software engineer. His first project was a new digital music product, code-named Oboe.<ref>{{cite news | url=http://computerworld.co.nz/news.nsf/UNID/A082F24382B9BE5CCC2570A0002C04C7 | title=DVD Jon now working for Linspire's Michael Robertson | publisher=Computerworld | first=Robert | last=McMillan | date=2005-10-21 | access-date=2007-08-14 | url-status=dead | archive-url=https://web.archive.org/web/20070927231357/http://computerworld.co.nz/news.nsf/UNID/A082F24382B9BE5CCC2570A0002C04C7 | archive-date=2007-09-27 }}</ref>

====Sony BMG DRM rootkit====
{{main|Sony BMG copy protection rootkit scandal}}

In November 2005, a Slashdot story claimed that [[Sony-BMG]]s [[Extended Copy Protection]] (XCP) DRM software includes code and comments (such as "copyright (c) Apple Computer, Inc. All Rights Reserved.") illegally copied from an iTunes DRM circumvention program by Johansen.<ref>{{cite web | url=http://yro.slashdot.org/comments.pl?sid=168546&cid=14051648 | title=Wow.
