# pkg2zip

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.

# 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](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.

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.
