09 F9 11 02 9D 74 E3 5B D8 41 56 C5 63 56 88 C0 is an HD-DVD decryption key that was leaked on April 30, 2007. The source of the leak is unclear. It is of interest to cryptographic researchers, as it can be used to play a protected HD-DVD movie in Linux, bypassing the normal DRM. The key will also allow for programs analagous to DeCSS for DVDs.

In a cease and desist order from the Advanced Access Content System Licensing Administrator addressed to Google Inc, the letter humorously included the code in question. [1]
