PSVita Release: psvpfstools lets you decrypt the PFS filesystem
Last week, PS Vita hacker motoharu released psvpfstools, a set of tools that lets you decrypt anything that’s PFS encrypted on the PS Vita.
decrypting the PFS Layer is already something that can be achieved via Vitashell on a hacked PS Vita. However, Psvpfstools runs the entire decryption task on a PC, without requiring a PS Vita. Motoharu states this can also be used to decrypt 3.61 Vita games and DLC, and it should theoretically work for higher firmware games as well.
Being able to decrypt games (among other things you might want to decrypt from the PS Vita) is useful for things such as mods or fan translations. Although most people were probably content with the possibility to do this directly on the PS Vita, being able to do it on a PC could help speed up the process. It also demonstrates that the whole decryption process has been figured out by the hacker.
Motoharu credits the following people for the release of psvpfstools:
- Proxima. For initial docs on DMAC5, providing F00D service and help with crypto theory.
- St4rk, weaknespase and everyone involved in PkgDecrypt. For zRIF string decode/inflate code.
- Chris Venter. For libb64.
- PolarSSL. For cryptographic primitives.

So will this allow backups for games that require 3.61?
No.
But i thought the issue was the encryption?
I think what it means is that it can theoretically decrypt 6.61+ games but we still need a 3.61+ kexploit to get the decryption key.
They can decrypt the files to see the contents of things like sounds and images, the file that actually boots the game requires another key which isn’t known
so can we patch the Japanese games that released before 3.61 but were 3.61+ in eu/us
Actually you are correct. In the literal use of the word “backup” then yes this should theoretically allow for one to back 3.61+ games up. As for the implied use of the word “backup”, no this is not possible to run backups as has already been answered.
“Although most people were probably (content) with the possibility to do this directly on the PS Vita, being able to do it on a PC could help speed up the process” what do you mean by people content? Lots of mods?
Using old methods to decrypt games directly on the Vita, they were content (as in satisfied, not something materialistic for lack of a better word) to use the Vita to handle PFS decryption.
Right thank you ^^
my 3.60 no update for a long time now. but for some reason it auto update and I don’t even friggin’ know. my home wifi off and vita not connected to internet for 3 month. just yesterday wifi on back and all I did is connect to wifi and vitashell turn on auto update. after that finish and I go to trophy and sync. and power off. today I just notice that my vita dissapear henkaku setting and check firmware and it fcking 3.65
I don’t know what the f is going on here. thanks to henkaku enso. I still can access to vitashell and modelshell and other game that I installed. now I don’t even feel like I want to power off or reboot. ***. this is happened to me. 3.65 fck. in setting I tried going to playstation network and it said need to update firmware. and when I go to system update and it said firmware is up to date. ***
I really need help guys. I don’t want to have 2 vita running 3.65. fck what have I done. I hope if I can replace something seem I still can access to my vitashell. hope if I can replace system. help me here.
so, does it have to do with henkaku for 3.61+ ???
Can someone share binaries for win7 64? I can’t compile from the source. Running bat file leaving me with a bunch of files and i can’t make executable from them. Any advice or compiled file would be welcome
