BackupHDDVD, a tool to decrypt AACS protected movies

Hi everyone.

I was not aware of anyone having done that, so I did.
BackupHDDVD is a tool to decrypt a AACS protected movie that you own, so you can play it back later using
an HDDVD player software.

This is the first version, and it's not very stable yet.

This software don't provide any cryptographic keys, so you have to add your own keys.

Watch:

Executable and source code:
http://rapidshare.com/files/8318838/...HDDVD.zip.html

Please read the FAQ before asking me any questions.

Merry Christmas everyone!

Yes, this is for real ;-)

This is real, any good java programmer can confirm this program make sense, and all that is missing is the decryption keys.

Take a look at the FAQ file for details...

I already have a version that works with volume key instead of title keys. Even more powerfull!

Version 1.0, with volume key support should be out on january 2.

I can verify that there are no viruses. I am reading the faq right now.

Even comes with the source.

Yeah, I've gotten that far too. It just seems too simple. We've all read the many news articles about how AACS cannot be decrypted but here is this program, so small, claiming it can do that.

We'll see.

EDIT: Very nice

supposedly the decryption keys come off the disk. well actually they are encrypted, but when played the keys are decrypted, the rest is kind of left a mystery by the author. Let's see what happens on January 2nd.

What sort of HD DVD drive do you have, muslix64?

I think he gets the keys from powerDVD. I am sure they will get some heat because of this.

the 'nice' thing about ACSS though is they can revote PowerDVD's current key which will not allow any future media to be decrypted w/o updating PowerDVD

If I understood correctly, the Title Keys were yanked from active memory, which would render revocation of PowerDVD's key moot. The player's key decrypts the encrypted title key which is the key needed to decrypt the video (somebody correct me if I'm wrong here).

Hence, if all you need is a way to yank the Title Keys, What's to prevent the next version of PowerDVD (or any software player, for that matter) from falling to this same tactic? They could also try to deauthorize the old software players and find some way to scramble the title keys in memory on the next versions, but reverse engineering the software itself to find the scrambling method will reveal those keys once again.

However, even if they do decide to go to an extreme and yank software players off the market (at least, for any OS other than the ass-puckered WinVista64), I could easily see someone cracking open a perfectly good HD-DVD player, probing the memory, and just create a list of HD-DVD keys that gets posted to some online website. The only trick is that you'd need to keep REAL QUIET on what players you're modified to pull title keys from.

That obviously would make it difficult for just anybody to make their own keys, so I foresee key distribution as the next big craze. This would relegate disc backups to an as needed sort of thing. You can back up a disc you bought if you really want (if, for example, you want to watch a movie on your laptop but prefer to leave the disc at home), but you'll need to go online and hunt down a key first.

I love it. It IS 100% LEGAL (Read you lawbooks on this!!!) to make a COPY of media you OWN (Reason why he did this, as he said, the media is VERY touchy to scratches.) "An individual is allowed to make 1 copy, per for archive purposes, of the media he owns. You, however, are not allowed to sell the copy, per said, for profit. "
Actually in large parts of Europe it's not illegal to make a copy for home use, but it IS illegal to break copy protections, even on your own bought movies, therefore usage of this tool is illegal imho

I don't know how strict the moderators are , so I'll say just this: the MD4 hash of the file is 4860e9248663d52dc47bfc98d61ec6d7

(and I don't see any problems with this, since a few posts above a direct HTTP link to the file was posted; mods, please be consistent )

Regards,

Posting an MD5 hash of a program is OK. Posting keys is not OK.

Nor is there need to somehow challenge the mod team to be consistent.

And again (though it becomes boring): the crypting algorithm (AES128) is in no way broken and thus HD-DVD is not "cracked".
I would be happy if these statements were true, but at the moment, they aren't and there's no hint they will be soon.

Yes it does, the SSL256bit encryption hasnt been cracked, its approx 402 numbers long, its 2 prime numbers multiplied together. there is a $1m prize for anyone who can crack it.

No, that doesn't mean that it's unbreakable as you claim. The only unbreakable encryption is a properly setup one time pad.

Eh, the hash is not MD5 but MD4. A hash code used in a popular P2P network. Knowing it is as knowing an URL, only better, since it can not break due to a closing of a single server.

PS: For easy use, the size of the file must also be known, it is 17964 bytes
