Xbox 360 Crypto

A collection of tools I've written for the Xbox 360

Most things work across Windows, macOS, and Linux but anything that requires packing or unpacking the CE/SE/5BL will only work on Windows.

This tool suite is BYOK (Bring Your Own Keys), you can verify your keys with verify_keys.py

XeCrypt.py

A library that includes most of the Xbox 360's cryptographic library.

harness.py

A script to test XeCrypt to make sure it's functioning properly.

MemCrypto.py

A script that replicates the Xbox 360's hardware memory encryption algorithm.

shadowboot.py

A shadowboot builder and extractor script.

kv_checker.py

A script that checks KV's to see if they're banned or unbanned.

kv_tool.py

A script to encrypt a KV and generate fuses for a zero fuse console.

nand_tool.py

A script that allows for modifying a NAND image for the Xbox 360, it automatically recalculates ECC bits and has address translation support.

patch_parser.py

A script that attempts to dump patch binaries to assembly.

xdk_extract.py

A script to dump XDK and recovery images to cabinet files.

xval.py

It's xval but in python, it checks to see if your console is possibly flagged.

xkelib_exports.py

This script was made to automate the SDK dumping process so that I can dynamically update exports for xkelib.

xcp.py

A script made to decrypt XCP files delivered by the Xbox 360 CDN.

hvx_signer.py

A script that can sign HvKeysExecute payloads.

cpu_key.py

A script that can generate valid CPU keys.

assembler.py

An interactive script that assembles PPC ASM to bytes in realtime.

patch_build_task.py

This script runs three scripts for building a zero fuse image:

• patch_compile.py - This script compiles patches for the zero fuse 4BL and 5BL.
• se_patcher.py - This script patches the 4BL/5BL with the patches generated with the compiler.
• patch_checker.py - This script checks the patches to make sure there's no address conflicts.

exp_build_task.py

This script builds the HV Peek/Poke expansion and outputs to a .h file, it uses:

• build_lib.py - This script contains assemble_patch which is useful for assembling PPC assembly.
• exp_signer.py - A script to sign HV expansions, this works on test kits using the 11775.3 recovery without modifications to the HV.
• bin2lang.py - A script to convert binaries into a format readable by a few programming languages.
