PSVPFSTools for Decrypting PS Vita PFS FileSystem by Motoharu Gosuto

We've seen a PFS Protection Bypass method, PFS Explorer Support, PlayStation File System Keys, MakePFS, pfsSKKey, and following his PSVGameSD update PlayStation Vita developer Motoharu Gosuto has since released PSVPFSTools for decrypting the PS Vita PFS filesystem!

dependencies

curl

Windows (example)

• Direct installation: https://curl.haxx.se/download.html
• Sources: https://github.com/curl/curl

It is easier to build curl from sources if your are on Windows. By default - it does not have any additional dependencies. However it looks like Windows binary distribution built with mingw requires openssl binaries:

• libssl-1_1.dll
• libcrypto-1_1.dll

You have to set these environment variables for cmake:

• CURL_INCLUDE_DIR=C:\Program Files (x86)\CURL\include
• CURL_LIBRARY=C:\Program Files (x86)\CURL\lib\libcurl_imp.lib

Ubuntu (example)

You can install curl library with apt-get: apt-get install libcurl4-gnutls-dev or libcurl4-openssl-dev

You have to set these environment variables for cmake:

• declare -x CURL_INCLUDE_DIR="/usr/include/"
• declare -x CURL_LIBRARY="/usr/lib/x86_64-linux-gnu/libcurl.so"

boost

Windows (example)

Any boost version should work out in theory. Build was tested with 1.55 and 1.65.1 Consult with this page for build: http://www.boost.org/doc/libs/1_65_1/more/getting_started/windows.html

You have to set these environment variables for cmake:

• BOOST_INCLUDEDIR=C:\boost_1_55_0
• BOOST_LIBRARYDIR=C:\boost_1_55_0\vc110\lib

Ubuntu (example)

You can install boost with apt-get: libboost-all-dev

You have to set these environment variables for cmake:

• declare -x BOOST_INCLUDEDIR="/usr/include/"
• declare -x BOOST_LIBRARYDIR="/usr/lib/x86_64-linux-gnu/"

build

Windows

Go to cmake folder and execute build.bat. It will create build folder and configure cmake to build with Visual Studio 2012. Code uses some c++ 11 features so lower Visual Studio is not recommended.

Ubuntu

Go to cmake folder and execute build.sh. It will create build folder and configure cmake to build with standard make.

run

Options:

-h [ --help ] Show help

-i [ --title_id_src ] arg Source directory that contains the application. Like PCSC00000.

-o [ --title_id_dst ] arg Destination directory where everything will be unpacked. Like PCSC00000_dec.

-k [ --klicensee ] arg klicensee hex coded string. Like 00112233445566778899AABBCCDDEEFF.

-z [ --zRIF ] arg zRIF string.

-f [ --f00d_url ] arg Url of F00D service.
