Question: I think if I see the numbers (are they numbers - there are letters there too) 09 f9 11 02 9d 74 e3 5b d8 41 56 c5 63 56 88 c0 one more time I think my eyeballs will fall out! These numbers seem to be everywhere! But what I don't get is what they are and why people are getting worked up about them?
Good question, and I'm sure that you're not alone in being confused.
Those numbers (and yes, they are numbers, but in hexadecimal form and not the decimal format that we're familiar with) for the processing key for most HD-DVD discs in circulation. This processing key can be used to decrypt and therefore make perfect copies of HD-DVD discs that use it.
What's interesting is that this processing key is only significant because the AACSLA (the AACS Licensing Authority) chose to use the same processing key for almost all HD-DVD discs produced. The idea was that each disc would use a different processing key but the AACSLA got overconfident and are now paying the price. The current round of legal threats by the AACSLA is an example of trying to stuff a genie back into a bottle. It just ain't gonna happen.
This processing key will now be replaced with newer ones (I don't see the AACSLA falling into the same trap twice and using the same key for all discs) and the processing key making the rounds now will only be of any use to decrypt current discs that use it.
