Updating aacs key
Each playback device comes with a binary tree of secret device and processing keys.The processing key in this tree, a requirement to play the AACS encrypted discs, is selected based on the device key and the information on the disc to be played.In a response to the events occurring on Digg and the call to "Spread this number", the key was rapidly posted to thousands of pages, blogs and wikis across the Internet. My legally purchased copy of Power DVD is refusing to play Bluray discs made after a certain date: Astonishingly, this is "standard practice" for all versions of Power DVD.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.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.The compromised players can still be used to view old discs, but not newer releases without encryption keys for the compromised players.

in which Eric Goldman at Santa Clara University's High Tech Law Institute noted that the illegality of putting the code up is questionable (that Section 230 of the Communications Decency Act may protect the provider when the material itself is not copyrighted), although continuing to allow posting of the key may be "risky", and entertainment lawyer Carole Handler noted that even if the material is illegal, laws such as the DMCA may prove ineffective in a practical sense. On May 7, 2007, the AACS LA announced on its website that it had "requested the removal solely of illegal circumvention tools, including encryption keys, from a number of web sites", and that it had "not requested the removal or deletion of any ... The statement continued, "AACS LA is encouraged by the cooperation it has received thus far from the numerous web sites that have chosen to address their legal obligations in a responsible manner." BBC News had earlier quoted an AACS executive saying that bloggers "crossed the line", that AACS was looking at "legal and technical tools" to confront those who published the key, and that the events involving Digg were an "interesting new twist".
