If other players are then cracked, further revocation would lead to legitimate users of compromised players being forced to upgrade or replace their player software or firmware in order to view new discs. The compromised players can still be used to view old discs, but not newer releases without encryption keys for the compromised players. Therefore, the "09 F9" key is only one of many parts that are needed to play a disc on an unlicensed player.ĪACS can be used to revoke a key of a specific playback device, after it is known to have been compromised, as it has for WinDVD.

There are several interlocking encryption mechanisms, such that cracking one part of the system does not necessarily crack other parts.
Ĭommercial HD DVDs and Blu-ray discs integrate copy protection technology specified by the AACS LA. Opponents to the expansion of the scope of copyright criticize the idea of making a particular number illegal. Since it is a 128-bit numerical value, it was dubbed an illegal number. īecause the encryption key may be used as part of circumvention technology forbidden by the DMCA, its possession and distribution has been viewed as illegal by the AACS, as well as by some legal professionals. The key is an ordinary number most widely known by its hexadecimal representation in decimal notation, when interpreted as an integer, it is 13,256,278,887,989,457,651,018,865,901,401,704,640. Hexadecimal is a base-16 numeral system used in the fields of computer programming and mathematics. The AACS LA described this situation as an "interesting new twist".
This sparked what some describe as a digital revolt or "cyber-riot", in which users posted and spread the key on Digg, and throughout the Internet en masse, thereby leading to a Streisand effect. The controversy was further escalated in early May 2007, when aggregate news site Digg received a DMCA cease and desist notice and then removed numerous articles on the matter and banned users reposting the information. In response to widespread Internet postings of the key, the AACS LA issued various press statements, praising those websites that complied with their requests for acting in a "responsible manner" and warning that "legal and technical tools" were adapting to the situation. The letters demanded the immediate removal of the key and any links to it, citing the anti-circumvention provisions of the United States Digital Millennium Copyright Act (DMCA). Ī controversy surrounding the AACS cryptographic key arose in April 2007 when the Motion Picture Association of America and the Advanced Access Content System Licensing Administrator, LLC (AACS LA) began issuing cease and desist letters to websites publishing a 128- bit (16- byte) number, represented in hexadecimal as 09 F9 11 02 9D 74 E3 5B D8 41 56 C5 63 56 88 C0 (commonly referred to as 09 F9), a cryptographic key for HD DVDs and Blu-ray Discs. The byte "C0" is appended in the lower right corner (due to 16 not being divisible by 3). The first fifteen bytes of the 09 F9 key are contained in the RGB encoding of the five colors, with each color providing three bytes of the key.

Internet users began circulating versions of this image, calling it the Free Speech Flag, in blog posts on dozens of websites and as user avatars on forums such as Digg.
