Anyone interested in the history of DVD DRM / region locking may be interested in the "illegal number": a hex code which defeated DVD AACS encryption, prompting an attempt by the industry to surpress it across the internet, leading to a streisand effect and the end of effective DVD DRM.

- gjsman-1000 4y agoThat was a leaked Blu-ray Processing Key that was quickly revoked - but the industry was livid that it was allowed to propagate before they could revoke it (which takes 90 days). This means, ultimately, that if you have a player that hasn't had a Blu-ray Disc made since 2008 inserted into it, and are trying to decrypt a disc made before ~2008, then maybe with the right tools you could. It's a shallow victory meaningless nowadays. [Even then, a Processing Key isn't nearly as interesting as a Device Key, plenty of which have been leaked since without much attention. Blu-ray has so many keys...]
- account42 4y agoStripping Blu-Ray encryption works just fine with MakeMKV (and other tools). Even UHD disks if you have a LibreDrive-compatible reader. Sure, it requires someone to decrypt the individual disks keys and distribute those but in practice it just works for anything that is not a brand new release.
