## What it is
A set of Python scripts for decrypting Intel Atom CPU microcode updates, using encryption keys extracted via the Red Unlock debugging technique. It also unpacks decrypted XuCode (SGX software) images for Goldmont Plus CPUs.

## Use cases
- decrypt intel atom microcode update binaries
- analyze x86 microcode internal structure
- unpack xucode elf images from goldmont plus
- research intel cpu microcode encryption keys
- extract microcode from apollo lake or gemini lake cpus

## When to choose
- you need to decrypt Intel Atom (Goldmont/Goldmont Plus) microcode updates for security research
- you want to study the internal structure of x86 microcode or XuCode

## When to avoid
- you want to create or modify custom microcode updates (only decryption is supported)
- your CPU is not Apollo Lake or Gemini Lake generation
- you need a supported, production-grade tool

## Facets
- artifact type: cli-tool
- maturity: maintenance
- function: cryptography, reverse-engineering, parser, security
- domain: security, reverse-engineering, hardware, developer-tools
- platform: python, cli, cross-platform
- tags: intel-microcode, rc4-decryption, red-unlock, x86, firmware-analysis, cpu-research
