Soooo... PS3 encryption? by Hotcakes at 10:32 PM EDT on August 22, 2010
I've only been reading the headlines so I'm not all up on the ins of PS Jailbreak, but I did read one bit where it was italics speculated that PS Jailbreak doesn't decrypt files on the fly, but must decrypt files as it copies them to the hard drive.
So... anybody following the developments or looked/looking into a couple of games to see if they can find anything?
IIRC PS3 discs have an encryption layer that's only read when the PS3 OS is running and is ignored when running "OtherOS". Along with that, game files remain encrypted with another encryption by the devs. For PSN stuff, when installing to the HDD, the PS3 decrypts it when installing. When backing up a PS3 HDD, it encrypts everything and decrypts it when restoring it back to the PS3.
Okay so wait PS jailbreak backup manager doesn't decrypt the game while backing up to internal PS3 HD or external Hard drive?
I heard also it copies file by file instead of an iso, so thats a sign o decryption? i would of thought since ps jailbreak tricsk the ps3 into thinking its a debug console then it should decrypt the games files as its dumping?
Yeah - the disk layer of encryption has been stripped (the PS3 does it natively) however the actual SELF layer of encryption is still on the EBOOT.BIN.
Hopefully someone uploads thme toa filehosting site, im real itchy to get my hands on a derypted game.
also about ps3's codec
The PlayStation3 game Race Driver: Grid uses 224 simultaneous streams of ATRAC3 compressed audio, with between one and eight channels per stream at sample rates between 24 and 48 KHz, each filtered using 512 frequency bands of adaptive equalisation, routed via six reverb units running on the same SPU co-processor (one of eight on the PS3's Cell chip), alongside 7.1 channel hybrid third-order Ambisonic mixing.[6]
