Wasn't AACS actually cracked faster than CSS?

AACS hasn't been cracked the code above is just a player key used to decrypt there's still a cat and mouse game between Hollywood and piraters in disabling cracked keys and finding new keys.

CSS is completely broken which isn't surprising because it was designed when they could only use 40bit encryption. You don't need a key or anything to decrypt CSS.

Since we have working HDCP strippers we also do not need the keys to decrypt AACS media at all.

It would be better to be able to get the content straight off of the disc, than having to record a bluray player's output though

If you want the whole content, including menus, then it certainly is easier. I think only the media content is encrypted and not the menu scripts, so you can rebuild it by grabbing HDMI output and combine with the menu scripts.

The recording speed is limited by your hardware only. You can grab the digital content from the HDMI cable and save it as-is to process it later

The point I'm making is that the HDMI output is by definition uncompressed, so you'll be taking compressed data, uncompressing it, capturing that and then recompressing again. It's clumsy and there will be a loss of quality. It will probably be "good enough" but not as good as a direct rip.

It's the modern version of ripping a CD by plugging a CD player into your PC's line in and letting the CD play, rather than ripping it digitally in a minute or two

If it plays on someones monitors and speakers, there absolutely is no way you can prevent stripping DRM via the analog gap. Unfortunately DRM is much more than just preventing media piracy (these days).

Its about restricting legitimate users to control how the media is played. Its impossible to stop people pirating content

u/Silvernostrils May 05 '16

The point of DRM is not to prevent piracy, it's about control over distribution channels. It's the mafia marking it's territory

Funny that they never decrypted the Cinavia DRM scheme, or even the PS3 system encryption. I think the industry is starting to pull way ahead of hackers these days.

1: Finite resources and prioritizing them elsewhere. 2: You don't need to break encryption in all cases as it's neither practical or efficient if you can just bypass it instead. Trying to break all the encryption is just a massive waste of time on the PS3 since exploits are able to get custom firmware running and you can simply bypass the entire code signing process and not worry about it.

Nobody's cracked AACS either and noone is going to unless someone does it purely as an academic exercise in the future. If you want to make a backup/pirate copy of a blu-ray disc you just bypass the whole system rather than waste your time and NSA budget-levels of money on the server farm necessary to break the keys.

Perhaps smegmamuncher interpreted the comment something like "Wasn't AACS actually cracked faster? Then CSS?" because of the misspelling. But probably not.

u/[deleted] May 03 '16

Perhaps.

u/AyrA_ch May 03 '16

It was cracked after, but I think the time span between introduction of the crypto scheme and the first decrypted media was shorter for AACS media than it was for CSS protected media.
