Jon Lech Johansen
Jon Lech Johansen (* 18th November 1983 in Harstad , Norway ), the Internet also known as "DVD Jon", is co-author of DeCSS - Software . He was tried in 2002 because of the software at the instigation of the Motion Picture Association of America (MPAA) in Norway and acquitted.
In November 2003, published Johansen QTFairUse, an open source program, which raw data from QuickTime - AAC -Medien in a file store. This program could bypass DRM software such as that in the iTunes music store. Although these raw AAC files cannot be played by most media programs, they show a first attempt to bypass Apple's encryption .
Johansen is now a VideoLAN developer and wrote the FairPlay support for the VLC media player . Johansen was on trial again on December 2, 2003 because of DeCSS. The verdict on December 22, 2003 was acquittal. Økokrim , a Norwegian economic crime agency, announced on January 5, 2004 that it did not want to pursue the case any further.
On April 23, 2004 Johansen released another program: DeDRMS . This time written in C # and comprising 230 lines, this program also enables the copy protection to be removed.
In autumn 2005 Johansen caused a sensation in his home country Norway when he emigrated to the United States with a post on his blog entitled "10 things i don't miss about norway".
Johansen didn't stop there. On July 7th, 2004 he published FairKeys, a program with which you can obtain the keys you need for DeDRMS from the iTunes server yourself. On August 12, 2004, Johansen announced that he had cracked the encryption on Apple's AirPort Express .
SharpMusique is the name of the newest program; with it you can use the iTunes Store regardless of platform. The AES -encrypted music files legally purchased in the shop can be downloaded without DRM information and saved in an unprotected AAC format . However, the program has now stopped working because Apple improved the protection in the iTunes Music Store. So far this encryption could not be cracked.
At the end of October 2006, Johansen made a name for himself again when he announced that he had cracked the copy protection FairPlay from Apple , which is used on the iTunes music portal and on the Apple iPod . At the beginning of 2008 the corresponding software "doubleTwist" was presented, which was developed by the company of the same name and founded by Johansen and which enables the storage of protected music for end users of various devices.
At the beginning of July 2007, he cracked the Apple iPhone , which enabled the phone to use open WLAN hotspots without being activated by AT&T Wireless . This allows the iPhone software to be started with most of the functions. Telephoning was not yet possible.
