I ran into this problem getting the Disc Hash Key because the original game disc was using 4.21FW. The way I got around it was, I downgraded to 3.55, Installed `Data Dumper` (data_dumper.pkg) and `Disc Key Dumper Loader` (disc_key_dumper_loader.pkg) then Rebooted console. Converted the game eboot to 3.55, Loaded the dumped game with multiMAN, then I put the original disc into the drive and started `Disc Key Dumper Loader`, and then I loaded the game from disc icon. After exiting from the game I ran `Data Dumper`.
After that, I managed to get the key.

i also tried this..
i was able to get a key but i suspect the key is incorrect..
i applied the dumped key to the conf file but pfdtool reported Disc Hash Key Hash: FAIL.

Did you open up the dump with a text editor or a hex editor? Because the key is in text format, not hex.

ah damn... oh well. pure curiosity here, but is/would it be possible to bruteforce the disc hash key in a similar way to getting the secure id? i'm guessing it would take ages... but could it theoretically be possible?

and what about reading off the disc itself? ie: putting the game disc into my pc's bluray drive? would that help?

btw, thx for an awesome tool in anycase!

hey can any1 answer this
Say suppose there is a trophy for 100 kills with 9mm.
I got a save from other user with 99 kills with 9mm
I resign the save with this tool with mine and load it on my ps3.
So if I just get 1 more kill will I get the trophy??

thanks

Depends if you are trying to get the online or single player trophy. In case of single player - yes you get the trophy (in a lot of games you get it even when your friends save game has more than 100 kills. You just have to do one more).

With multiplayer usually no - stats are kept on server. There are exceptions and some games allow you to get online trophies when you have never played online before.

thanks man for the quick answer

There are a new key transformation algorithm (it is different from the one used for save games) based on your UserID and Console ID and new keys, of course. PS3 have a bunch of these static keys for every protected file inside a database. They are similar to secure file ID which used for save games. At the moment I'm not sure that trophy keys should be published because it will endanger the trophy system completely... Who wants a broken trophy system because some cheaters want to hack their trophies online?

Agreed, too bad that the system is broken already. There are people who are selling the trophies (time consuming ones and the ones that can't be obtained with save game hack) so I must assume there are more people with those keys already.

Feel kind of stupid that I spent 100h+ this summer to get my Far Cry 2 plat . Oh well, at least I met some nice people.

I myself would use those keys to get some trophies that can't be done legit anymore (FIFA and NHL 2K10 online servers have been taken offline). But then again - I suspect sooner or later those keys will be public and trophies will be pointless anyway. Well even save game hack have degraded their value.

PS! flat_z thanx for the tools.

Yeah, I can but only for future releases because the only thing which needs to be implemented is proper error handling/info.

No, it is not required for encryption/decryption. It is just a hash and nothing more.

If game developers wants they can change it. But such updates will break save game compability.

Yes, you are right.

Yes, you can modify and use it without a proper disc hash key.

Yeah, you can use this way too. But I believe that I'll finish my new dumpers on this week. I already ported the Klicensee Dumper and other dumpers have the same principle so I can easily port them.

Yes, it is possible if you will use a decrypted form of disc hash key because they use AES128 over it. By using this method you will need to bruteforce 5 bytes because the rest bytes are almost zeroes. Although you also need an AES key and the custom algorithm to bruteforce it.

We don't know about the algorithm which used to get the disc hash key. I only know that the Blu Ray sent it to the PS3 when the PS3 sent a specific secure command to the Blu Ray drive itself.

Ok guys, been following this thread since day 1.
I tried to get a foreign God of War3 save to work with my PS3 and i don't get it.
I've got all keys, except the disc_hash_key (which i've read is not necesserary for just resigning).
If i use Aldos BruteforceSaveData, i see that the save is protected.

What should i do to make it inject my ConsoleID + AccountID ?
I tried all options (patch sfo, decrypt/update/encrypt/verify PFD) with no success.
Should i only use Flatz tools instead ?

Thanks a lot for your help and have a nice day.
