Multi PKG Tool to Decrypt / Extract PS3, PSP and PS Vita PKG Files

350°

61w ago - Following up on his previous release, today PlayStation Vita developer PsDev has made available a Multi PKG Tool which now allows users to decrypt and extract PS3, PSP, and PS Vita PKG files.

Download: Multi PKG Tool v.1.0.0.1

To quote: This Tool can decrypt and extract Playstation Vita, Playstation Portable or Playstation 3 retail pkg.

It uses the PSP/PS3 AES key that is used to decrypt and extract PSP/PS3 retail pkg. However, No longer can Playstation Vita PKG over beta/retail 1.00+ be decrypted and extracted with the PSP AES key.

AES Keys used

private byte[] PSPAesKey = new byte[16] {
0x07, 0xF2, 0xC6, 0x82, 0x90, 0xB5, 0x0D, 0x2C,
0x33, 0x81, 0x8D, 0x70, 0x9B, 0x60, 0xE6, 0x2B

private byte[] PS3AesKey = new byte[16] {
0x2E, 0x7B, 0x71, 0xD7, 0xC9, 0xC9, 0xA1, 0x4E,
0xA3, 0x22, 0x1F, 0x18, 0x88, 0x28, 0xB8, 0xF8

I would like to give a big, big, big thanks to Mathieulh, Because I used his AES Engine to decrypt PS3 retail pkg, Without that it could have taken me way longer to make this tool.

Download: Grafchokolo PSGroove Payload / Grafchokolo GIT

To quote: "So guys, I promised to you that I will made my PSGroove payload public.

I just uploaded it to github. Let me first explain how it works. I do not have much free time, so please do not expect me to explain every detail to you. The target group of this release are advanced programmers among you. The source code is not commented but it's clean, well structured and self-explaining.

My payload has 2 stages. The 1st stage is actually a PSGroove payload. It initializes the gelic device and allocates memory needed for the 2nd stage. Just compile the 1st stage binary, convert it to C hex array and replace the PSGroove payload.

The 2nd stage does the real job, e.g. decrypts a CORE_OS_PACKAGE.pkg from a PUP file, runs some isolated SPU module or dumps...
