PkgDecrypt is a command line tool to decrypt and extract PS Vita .pkg files.

Features

• 1:1 file extraction.
• Support for klicensee and zRIF keys for work.bin 1:1 recreation.
• Can either extract PKG or decrypt it into PKGS file.
• Different output hierarchies can be chosen for easy transfer to Vita.

User guide

Requirements

• Windows x64 (for precompiled build) or other supported OS.
• a) Vita with 3.60 henkaku, PKG file and license key [klicensee(deprecated) or zRIF(recommended)] for Vita installation,
• b) PKG file for extraction purposes only.

Dependencies

• zlib.

How To Use PkgDecrypt

pkg_dec [--make-dirs=id|ux] [--license=<key>] [--raw] filename.pkg [output_directory]
    --make-dirs=id|ux   Use output directory to create special hierarchy,
                id  places all output in the <CONTENTID> folder
                ux  places all output in ux0-style hierarchy
    --license=<key>       Provide key to use as base for work.bin (*.rif) file creation.
                Two formats accepted - klicensee key (deprecated) and zRIF (recommended)
                zRIF could be made by NoNpDrm fake RIFs using make_key
    --raw           Output fully decrypted PKG instead of unpacking it, exclusive
    <filename.pkg>        Input PKG file
    <output_directory>    Directory where all files will be places. Current directory by default.

Changelog

1.1.0.0

New features:

• Support of generating fake RIFs from hex-encoded klicensee and zRIFs.
• Unpacking files using ux0 hierarchy emulation.
• Automatic recognition of DLC and GD packages (using pkg_info fields).
• make_key program to pack fake RIFs into zRIF format.

Major refactoring of code:

• Split code over few modules, for example, key encoding and decoding done using keyflate.c.
• Few utility functions (mkdirs and set of pkg_* functions mirroring stdio with transparent decryption).
• Improved code readability with structs defining various structures in pkg file.

Bugfixes:

• Generated head.bin now have proper file size.
• Attempted to fix sku_flag value using drm_type of package (different solution from temp.bin).
• Other bugfixes.

1.0.0.3

• Added full support for license keys, now if you use license key it will generate fully working work.bin file.
• Added check for license, if license is not used, file work.bin will not be generated at all.
