176w ago - Following up on the PS Vita 1.50 Firmware announcement comes news this weekend from PlayStation Vita hacker SKFU who has confirmed the PS Vita PKG AES Key has changed.

To quote from his blog: I just got my tried to unpack the Twitter application for PS VITA and sadly I have to say that the AES key for PKG encryption and decryption changed.

The PKG's I used for my testings were pretty old and the key update was expected. Nevertheless it's a bit disappointing but a new nice challange

The PS3 can decrypt the new packages on firmware 4.00 which contains the new PS VITA PKG AES key for the PS3 <--> PS VITA content exchange feature. This means we can decrypt and get the content of the PS VITA PKG files via a 4.00 PS3. Sadly there's no solution to re-encrypt it again, yet.

Let the games begin! (again...)

No big update of my works but here the driver PS Vita libusb a made for Windows (x86/x64). you don't need to use anymore the generic driver ps vita from Sony.

Oh yes just to clarify about the 3 python script i made. This is nothing comparatively to the full script i'm making, the 3 script are here to show you that you can communicate with the PS Vita, about the helloworld, funny how some people didn't understand how the python script works.

First : I ask if the PS Vita is connected to my comp
Second : I ask to the PS Vita the information of the USB configuration
Third : I send a message to the PS Vita and the PS Vita confirm the reception with a Hello World.
The PS Vita can't really answer to a question but can confirm that received the question. I write the answer Hello World for the PS Vita to confirm the message a send to the PS Vita has received, if the PS Vita didn't received the message, i would have a error and not the print hello world.

Is like every Hello World, it's you write the HelloWorld and it's the product show the Hello World but the product don't understand what that mean.

You need to think that have different possibility to make a hello world possible on every platform.

Sure that the Hello World is not impressive but like i said it's one of the investigation that show you where to work.

About the claim some user have read my news post on monkeydesk and posted it on gbatemp but i or you never sayed that you have HACKed the con. I named the news with "PS Vita Hot News" and translated some posts into german.

This guy then made the post with "PS Vita hacked?" or kinda like that and his first words written was like "nabnab claims to have the ps vita hacked" but some other guyes on gbatemp with a higher rep teached them they should learn to read

Now it seems they understand. But i haven't read anything about that to copy a savegame exploit to the vita we will need your work, the debug mode enabled to get full access to file sys and place the exploit where we need them. Also im sure we can get hands on on some nice importend files of the vitas fw. But anyway they will fully understand when it's time for it

USB Debug mode allow more than we expect but it's pretty unstable for now. Every person who have a PS Vita can do it and without anything else than a PS Vita and computer

Oh yes i saw that some people said that i claim i have hacked the PS Vita. I have never said i hacked the PS Vita, i explain what i have discovered and what my investigation/work is about.

Actually some executions on the PS Vita are pretty unstable and give me some errors (a security from the PS Vita that i need to fix) but i am working on it. I keep you informed for any updates of all my work and i will show you how to reproduce it when it's easy to do but need to keep it a bit as a secret before the EU/US release.

Nothing about my works but i really recommend to use the last version of openCMA http://code.google.com/p/procfw/downloads/detail?name=opencma_r3.7z on Windows -> thanks to Virtuous Flame

Ok let's back to work now

Nabnab: Does USB debug mode allow much/anything that couldn't be done before? Or is it still in the investigation stage? Also, is it hard to get into, or is it something anyone could do?

Yep, you can always start a new thread and we can merge or promote any posts made from it to the main page.. this was our ongoing thread for the Vita FW and Content Manager so people started posting here but if you wish to start your own I'm all for that too!

I'm gonna wait the BIG BOSS if he/she (she -> just kidding what ! you never know) want to make a new Thread and move all on this thread, it's gonna be more easy to follow and update the works.

You could do a new Thread named with "Universal Vita Dev Thread" or kinda like that. But best would be to ask the boss he also can move all the stuff from here which hase nothing to do with the OCM to this new thread then.

Great about the wiki and shows you that maybe more peoples recognize your work then yourself expect

I also was surprised as i have googled for my work and have seen where else it get spreaded.
