: It is often required as the "PKG decryptor" in the NPS Browser settings to automatically unpack games after they finish downloading. Common Commands
Place your downloaded game.pkg file into the same folder as pkg2zip.exe .
: It uses a specific zRIF string (a license key) to decrypt the contents of the package.
Pkg2zip natively decodes a broad spectrum of digital software distributed across various PlayStation generations: Platform Category Supported File Type Target Directory Layout / Use Case Main application packages ( .pkg ) Installs natively into ux0:app/ .

(a NoNpDRM license key) to decrypt the content. Once processed, the output is ready to be dropped directly onto your Vita's Pkg2zip.exe
: It uses a specific zRIF string (a license key) to decrypt the game content.
The tool takes a .pkg file and, if required, a "zRIF" string (a fake license key) to create a standard directory or a .zip file that contains the game's decrypted assets. This allows users to manually install games and DLC directly to their console's storage (like an SD2Vita adapter ). There are two primary ways to use the tool:
: It utilizes AESNI hardware acceleration on compatible processors (requiring AESNI and SSSE3 instruction sets), significantly reducing decryption time.
It runs natively on Windows via the command prompt without requiring massive framework installations or external runtimes. : It is often required as the "PKG
To run the application, open your Command Prompt, navigate to your folder, and use the following basic syntax: pkg2zip.exe [package.pkg] [zRIF_string] Use code with caution.
In this post, I’ll explain what pkg2zip does, how to use it, and share some real-world examples.
To extract to a custom location:
The tool's main purpose is to convert encrypted .pkg files into a format that the PS Vita can recognize, such as a folder structure for the LiveArea or a standard .zip file. Pkg2zip natively decodes a broad spectrum of digital
: Written in cross-platform C with no external dependencies; it uses AESNI hardware acceleration for extremely fast decryption if supported by your CPU.
Because pkg2zip.exe is a (CLI), it does not have a Graphical User Interface (GUI). You must use Command Prompt (Windows) or Terminal (macOS/Linux) to interact with it. 1. Prerequisites pkg2zip.exe (downloaded from GitHub). The .pkg file you want to decrypt.
