PS3Dec

An alternative ISO encryptor/decryptor for PS3 disc images by red_meryl, originally posted on the k3y forums.

This is a slightly modified version of PS3Dec r5, using statically-linked mbedTLS for AES encryption/decryption and CMake as the build system.

Original README

PS3Dec r5
---
Encrypt/Decrypt a PS3 disc image. Supports original images (if user supplies
the key) and 3k3y images.

Usage: PS3Dec <mode> <type> [type_op] in [out]

If out is not defined, name is in.something, as appropriate

<mode>: 'd' for decrypt
        'e' for encrypt
<type>: "3k3y" for a 3k3y image (requires no type_op)
        "d1"   says type_op is d1 in hex form (32 char ascii) BEFORE
               it's been processed into the actual decryption key
        "key"  says type_op is the actual key in hex form (32 char
               ascii), aka d1 AFTER it has been processed, aka disc_key
---
Changes since r4:
*type renamed: "hex" to "d1"
*type added  : "key", the actual disc_key used to crypt
*type removed: "file", there's no standardised file format as yet. Until there
               is (if there is), this stays removed
*Can now compile elf 32bit

Dependencies

Windows

• Visual Studio 2017 (with Visual Studio C++ tools for CMake installed)

*nix

• A compiler with OpenMP support
• CMake
• Ninja (optional)

On macOS, libomp must be installed (available in Homebrew). The bundled version of mbedTLS will be used if it is not installed.

Compilation

Windows

1. git clone --recurse-submodules https://github.com/al3xtjames/PS3Dec
2. In Visual Studio: Select File > Open > CMake... and open PS3Dec/CMakeLists.txt
3. Change the current configuration to x64-Release
4. Select Build > Build Current Document (CMakeLists.txt)
5. Select CMake > Cache > Open Cache Folder (x64-Release Only) > PS3Dec
6. Run the PS3Dec binary (RelWithDebInfo\PS3Dec.exe)

*nix

1. git clone --recurse-submodules https://github.com/al3xtjames/PS3Dec && cd PS3Dec
2. mkdir build && cd build
3. cmake -G Ninja .. && ninja if Ninja is installed; otherwise, cmake .. && make
4. Run the PS3Dec binary (Release/PS3Dec)
