Raw

PkgDecrypt

Decrypts and extracts PS Vita PKG files.

Dependencies

  • zlib

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.

Usage

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.

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.

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,
  • All *.bin files are now generated in proper location output_folder/sce_sys/packages/*.bin

1.0.0.2

  • Fixed Windows extraction, now it extract 1:1 files.

1.0.0.1

  • St4rk's support for *.bin files

1.0.0.0

  • St4rk Initial code

ToDo list:

  • Fix DLC extraction,
