Re: First Vita Savedata Decryption
God if you could figure out a way to cross save between PCSX2 and Ps Vita that would be amazing! I have the undub version on my PC with widscreen hacks and such. I hope encryption is possible. If you can self convert this to PS3 I can self convert it to PCSX2!

Re: First Vita Savedata Decryption
As far as encrypting goes it may be possible to use the PS3 cross save feature to "encrypt" them if you will. This probably depends on how many checks the remote save servers have. Never the less I have modified a PS3 save before and have used cross save to get it onto the Vita.
Re: First Vita Savedata Decryption
op should try that
Re: First Vita Savedata Decryption
will I can convert a my psvita savedata for another psn account?

Re: First Vita Savedata Decryption
Can we have some more information about this save? What did you name Tidus, for example?
Re: First Vita Savedata Decryption
its the same ( tidus ) .. I think its similar to the ps3 ffx savesMrFwibbles wrote:Can we have some more information about this save? What did you name Tidus, for example?

No. This method doesn't involve knowing the algorithm.cryyifei wrote:So encryption algorithm is same?mr.gas wrote:its the same ( tidus ) .. I think its similar to the ps3 ffx savesMrFwibbles wrote:Can we have some more information about this save? What did you name Tidus, for example?
Instead, it allows to intercept the destination to where decrypted SAVEDATA is stored in the Vita.
Re-encryption will not be as trivial as some users think because Sony actually learned with past mistakes.
In the files that mr.gas provided you can see that save game data now enforces 4 kinds of encryption/verification:
- sce_pfs: The Vita's file system itself has a protection layer;
- clearsign: This is a key (header of the file is "pfsSKKey", just like in the PS4's save data files) that is used by the protected file system to verify/encrypt/decrypt contents (presumably, in a per block basis);
- ICV: The save game files have individual integrity check value files (or checksums) that are kept and controlled in a database;
- keystone: This key is involved in PKG encryption/decryption/verification and it's highly likely to be used in the first encryption of a save game file.
I guess I should add this information to the devwiki.

it is very helpful .. thanks.
