Update: It's now
confirmed as a fake guys.
Today Spanish PS3 Developer
DemonHades has announced news that they may have decrypted the Sony PS3 HDD. We will update the 'rumor' status of this when more questions are answered of course.
Several PS3 Devs including
NDT are currently investigating whether the method can be repeated in other PS3 consoles, or just for one console only (possibly brute-forced?) as it's already known the key differs between each.
Below is a picture of a font on the PS3 decrypted, followed by some preliminary (roughly translated) details:
The key is 512bytes is a sha1-4096 (512 bytes per sector). The key is xoreada own... To be sure it was not a simple xor as speculation... text still appears ... /cell_mw_cfs and more text:
Ps1SaveData
PspSaveData tb
PspSaveData.parentalLevel
PspSaveData.broken
PspSaveData.timeModified
PspSaveData.size
PspSaveData.sdTitle
PspSaveData.detail
PspSaveData.backUpDirName
PspSaveData.tmpDirName
PspSaveData.param1
PspSaveData.param2
PspSaveData.param3
PspSaveData.param4
The method I can/should I even say it is very close to an update could change the key or decryption/encryption. The first is to investigate all of its content and then go looking at what interests us is that we have to go 40gbs decoding one by one and is not easy.
But since you said that all the published info that this method allows for and is something that decode the hdd, as advice... I will not make an actualizar. It's about read PS3 hdd content (512 bytes xored key has been decoded), by the moment this means that hard disk content could be read, but not all info about this have been revealed.
Sorry for my English use google translator does not speak English, you can use this on CFW 4.30 R-DEX "REBUG"?...
Here's the thing.. SHA1 is a one way cryptographic function, once its hashed, it can not be "decrypted" by any known key, short of either having the original, unencrypted data to then re-encrypt and compare, or essentially brute-forcing it, its only going in one direction.
In which case, the PS3 would not use SHA1 "Encryption" to encrypt the files on the hard disk, as there would be no plausible way of decrypting them. Not to mention the fact that, yet again, its creates a hash, it doesn't do any "encryption" per-se.
Yes, the PS3 does use the SHA1 hash function in other areas, but more as a "checksum", to ensure data has not been tampered with, not as an encryption.
Take AES for example, a "two way" system, data can be both encrypted, and decrypted "at will", but straight SHA1 is just a hash, nothing more!
SHA1 = 160bit/512bit blocks
SHA512 = 512bit/1024bit blocks... if he PS3 HDD was SHA-512, it won't be getting decrypted anytime in your lifetime, perhaps not even in your childs lifetime. even SHA-256 most likely won't get broken AND you can't tell the difference between SHA-1 AND SHA-256 algos, especially if the data is padded.
In reply to NDT's question there: i'm writing in english because i can't understand spanish at all. can someone explain me if the HDD has been decripted using a method that can be repeated in other consoles or just for 1 console only? (maybe is was just brute-forced or something like that).
If anyone can do better translations feel free.
