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

Optionally saves [NoNpDrm](https://github.com/TheOfficialFloW/NoNpDrm) license into work.bin file. You must provide license key.

DLC support available when VitaShell will include [this pull request](https://github.com/TheOfficialFloW/VitaShell/pull/310).

# Features

* **portable**, written in cross-platform C code, runs on Windows, GNU/Linux, macOS (system dependent functionality is isolated in sys.c file).
* **small**, has no external library dependencies and uses very minimal dynamic memory allocations.
* **fast**, uses AESNI hardware accelerated AES decryption if supported by CPU (requires [AESNI](https://en.wikipedia.org/wiki/AES_instruction_set) and [SSSE3](https://en.wikipedia.org/wiki/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.
* **DLC** and **PATCH** pkg support.

Limitations:

* currently no PSM or update pkg files are supported.

# Usage

If you have zRIF fake license, then execute:

    pkg2zip package.pkg zRIF_STRING

This will create `title [id] [region].zip` file. Title, ID and region is automatically detected from pkg file. It will include work.bin file.

If you don't have zRIF fake license, but just want to unpack files, then omit last argument:

    pkg2zip package.pkg

Resulting zip file will not include work.bin. This is useful for patch pkg files.

# 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.

# Building

Execute `make` if you are on GNU/Linux or macOS.

On Windows you can build either with MinGW (get [MinGW-w64](http://www.msys2.org/)) or [Visual Studio 2017 Community Edition](https://www.visualstudio.com/vs/community/).
* for MinGW make sure you have make installed, and then execute `mingw32-make`
