Decrypts PlayStation Vita pkg file and packages to zip archive

pkg2zip

Utility that decrypts PlayStation Vita pkg file and creates zip package.

Optionally saves NoNpDrm license into work.bin file. You must provide license key.

Features

• portable, written in cross-platform C code, runs on Windows, GNU/Linux, macOS (system dependent functionality is isolated in sys.c file).
• small, uses zero dynamic memory allocations and has no external library dependencies.
• fast, uses AESNI hardware accelerated AES decryption if supported by CPU (requires AESNI and SSSE3 instructions).
• simple, creates zip package with same folder structure that Vita expects (just drag & drop all file from zip archive to ux0:). Zip file is created directly from pkg without any intermediate temporary files.

Limitations:

• currently works only for main application pkg files, no DLC.

Usage

Execute pkg2zip package.pkg to create title [id] [region].zip file. Title, ID and region is automatically detected from pkg file.

If you have raw license key (32 hex characters) you can execute pkg2zip package.pkg hexkey to try to generate work.bin file (works for most pkg files).

If you have working zRIF string, then execute pkg2zip package.pkg zRIF_string to create work.bin file from zRIF encoding.

Generating zRIF string

If you have working main.bin file you can create zRIF string with rif2zrif.py python script:

$ python rif2zrif.py path/to/main.bin

It will print zRIF string to stdout.

To generate main.bin from zRIF string use zrif2rif.py script:

$ python zrif2rif.py zRIF work.bin

Last argument is optional, it specifies where to save file and defaults to work.bin name.
