Blu-ray Now Cracked, and That Makes Two

Illustration for article titled Blu-ray Now Cracked, and That Makes Two

Movie studios, start your attorneys, because muslix64, the guy who cracked HD DVD with his BackupHDDVD utility has done it again. His next Pandora's box is called BackupBluray. It's not perfect yet, because the first iteration can only crack backup Blu-ray discs whose CPS unit key is known, but sources say full decryption will be added soon.


Of course, all of this unraveling of Blu-ray and HD DVD's bulletproof security is for backup purposes only. Certainly those who have bought these discs should be allowed to store away a backup for safekeeping, you know, in case the disc gets scratched? But we thought these encryption schemes were impossible to crack. Perhaps "impossible" is a relative term.

Standard disclaimer of "uneducated Gizmodo geek trying to pretend he knows something" applies:

Correct me if I am wrong, but I thought the CPS unit key is essentially the encryption key. Without it, you can not break the disc. Much like any other security key, if you have the key it is not a surprise that you would be able to access the data.

So, I am not so certain that anything has been broken. And, did I not read somewhere that, even if you knew the key, that they can change it? What becomes interesting is if it can be broken without the need for a key. Right?
