Editing Jon Lech Johansen (section)

==Other projects==
{{prose|section|date=December 2016}}

In the first decade of the 21st century, Johansen's career has included many other projects.

===2001===
In 2001, Johansen released OpenJaz, a reverse-engineered set of drivers for Linux, BeOS and Windows 2000 that allow operation of the JazPiper MP3 digital audio player without its proprietary drivers.

===2003===
In November 2003, Johansen released [[QTFairUse]], an open source program which dumps the raw output of a QuickTime Advanced Audio Coding (AAC) stream to a file, which could bypass the [[digital rights management]] (DRM) software used to encrypt content of music from media such as those distributed by the iTunes Music Store, [[Apple Inc.|Apple Computer]]'s online music store. Although these resulting raw AAC files were unplayable by most media players at the time of release, they represent the first attempt at circumventing Apple's encryption.

===2004===
Johansen had by now become a [[VideoLAN]] developer, and had reverse engineered [[FairPlay]] and written VLC's FairPlay support.<ref>{{cite news | url=http://boingboing.net/2004/03/26/dvd_jon_on_vlc_and_a.html | title=DVD Jon on VLC and Apple's iTunes singles | publisher=Boing Boing | first=Cory | last=Doctorow | author-link=Cory Doctorow | date=2004-03-26 | access-date=2007-08-14 | url-status=dead | archive-url=https://web.archive.org/web/20070807093239/http://www.boingboing.net/2004/03/26/dvd_jon_on_vlc_and_a.html | archive-date=2007-08-07 }}</ref> It has been available in VideoLAN [[Concurrent Versions System|CVS]] since January 2004, but the first release to include FairPlay support is VLC 0.7.1 (released March 2, 2004).

===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.

===2006===
On January 8, 2006, Johansen revealed his intent to defeat the encryption of next-generation DVD encryption, [[Advanced Access Content System]] (AACS).<ref>{{cite news | url=http://nanocrew.net/2006/01/08/deaacscom/ | title=DeAACS.com | publisher=nanocr.eu | first=Jon Lech | last=Johansen | date=2006-01-08 | access-date=2007-08-14 | archive-date=2007-08-11 | archive-url=https://web.archive.org/web/20070811113119/http://nanocrew.net/2006/01/08/deaacscom/ | url-status=dead }}</ref> On June 7, 2006, he announced that he had moved to San Francisco and was joining DoubleTwist Ventures.<ref>{{cite news | url=http://nanocrew.net/2006/06/07/moved-to-san-francisco/ | title=Moved to San Francisco | publisher=nanocr.eu | first=Jon Lech | last=Johansen | date=2006-06-07 | access-date=2007-08-14}}</ref> In October 2006, Johansen and DoubleTwist Ventures announced they had reverse engineered Apple Computer's DRM for iTunes, called FairPlay. Rather than allow people to strip the DRM, DoubleTwist would license the ability to apply FairPlay to media companies who wanted their music and videos to play on the iPod, without having to sign a distribution contract with Apple.<ref>{{cite news|url=http://featured.gigaom.com/2006/10/02/dvd-jon-fairplays-apple/ |title=DVD Jon Fairplays Apple |publisher=GigaOM |first=Liz |last=Gannes |date=2006-10-02 |access-date=2007-08-14 |archive-url=https://web.archive.org/web/20061010144755/http://featured.gigaom.com/2006/10/02/dvd-jon-fairplays-apple/ |archive-date=2006-10-10 |url-status=dead }}</ref>

===2007===
In July 2007, Johansen managed to allow the iPhone to work as an iPod with WiFi, without AT&T activation.<ref>{{cite news | url=http://nanocr.eu/2007/07/03/iphone-without-att/ | title=iPhone Independence Day | publisher=nanocr.eu | first=Jon Lech | last=Johansen | date=2007-07-03 | access-date=2007-08-14}}</ref>

===2008===
On February 2, 2008, Johansen launched [[doubleTwist]], which allows customers to route around DRM in music files and convert files between various formats. The software converts digital music of any bitrate encoded with any popular codec into a format that can be played on any device.<ref>{{cite news|last=Richards |first=Jonathan |url=http://www.dvorak.org/blog/2008/02/20/hacker-breaks-link-between-itunes-and-the-ipod/ |title=Hacker breaks link between iTunes and the iPod |newspaper=Times Online |date=February 20, 2008 |access-date=December 20, 2011}}</ref>

=== 2009 ===
In June, he managed to get an advertisement for his application [[doubleTwist]] on the wall of the [[Bay Area Rapid Transit]] exit <ref>[[DoubleTwist#Controversy]]</ref> outside the San Francisco [[Apple Store]], just days before the 2009 [[WWDC]] event.<ref>{{cite news|last=Kincaid |first=Jason |url=https://techcrunch.com/2009/06/05/apple-gets-pwned-sf-store-is-now-advertising-dvd-jons-doubletwist/ |title=Apple Gets Pwned, SF Store Is Now Advertising DVD Jon's doubleTwist |work=TechCrunch |date=June 5, 2009 |access-date=December 20, 2011}}</ref> On June 9, it was reported that the advertisement was removed by BART for allegedly "being too dark" and not allowing enough light into the adjoining transit station.<ref>{{cite web|url=http://nanocr.eu/2009/06/09/the-cure-for-iphone-envy-the-story-behind-the-doubletwist-ad/ |title=The Cure for iPhone Envy: The story behind the doubleTwist ad |publisher=Jon Lech Johansen's blog |date=June 9, 2009 |access-date=December 20, 2011}}</ref> The advertisement was later redesigned and redeployed with a transparent background.<ref>{{cite web|url=http://nanocr.eu/2009/06/11/slideshow-of-the-new-doubletwist-ad/ |title=Slideshow of the new doubleTwist ad |publisher=Jon Lech Johansen's blog |date=June 11, 2009 |access-date=December 20, 2011}}</ref>
