The High Definition DVD encryption got cracked a couple of months back, but recently the AACS licensing authority have been threatening people who discuss it. At the core of this is the processing key, which can be used to decrypt all HD DVDs. The key is just a big number. The AACS assert that the number is illegal to disclose.
If you were counting a large number of something, you’d have to skip this particular number (or whisper it) because the AACS believe they control it.
Anyway, we don’t quite have the DMCA here in the UK, so I can write that number here:
09 F9 11 02 9D 74 E3 5B D8 41 56 C5 63 56 88 C0
Without this work, you could not play legally bought HD DVDs with free software applications. You could not play legally bought HD DVDs that were from another country. You could not transfer legally bought HD DVDs to your hard disk for easy access, or to your portable movie player.
One might argue that you shouldn’t be purchasing goods from a company that is at war with you. Whilst I agree, it’s not that easy to find companies that aren’t at war with you and I support work like this to take back our freedoms.
