## What it is
Obfuscator-LLVM is a fork of the LLVM compiler infrastructure that adds code obfuscation passes for software protection. It transforms compiled code with techniques like control-flow flattening, bogus control flow, and instruction substitution to hinder reverse engineering.

## Use cases
- obfuscate C/C++ binaries to resist reverse engineering
- protect proprietary algorithms in shipped native code
- apply control-flow flattening to compiled programs
- build software with LLVM passes that obscure logic
- harden binaries against static and dynamic analysis

## When to choose
- you need source-level obfuscation of C/C++ code via a compiler pass
- you want a well-cited, research-backed obfuscation tool
- you can build against LLVM 4.0 and accept an older toolchain

## When to avoid
- you need support for modern LLVM versions or recent C++ standards
- you want actively developed obfuscation features
- you need obfuscation for languages other than C/C++

## Facets
- artifact type: library

- domain: security, compilers, developer-tools
- platform: windows, cpp
