## What it is
A macro-only C header library that obfuscates code at compile time, designed for the Tiny C Compiler on Windows x86/x64. It provides control-flow mutation, string hiding, anti-debugging, anti-decompilation tricks, fake packer signatures, and a math virtualization mode.

## Use cases
- obfuscate a C program at compile time
- hide strings in a C binary from reverse engineers
- add anti-debugging protection to a Windows C app
- break decompiler output for my C code
- protect a CTF crackme from analysis
- confuse control flow in C code with macros

## When to choose
- you compile C with Tiny C Compiler on Windows x86/x64 and want zero-dependency obfuscation
- you want a single-header, macro-based protection layer without external tooling
- you're building CTF challenges or educational demos of obfuscation techniques

## When to avoid
- you need obfuscation for GCC/Clang or non-Windows targets
- you require formally verified or industry-grade software protection/DRM
- you need readable, maintainable production code - obfuscation will hurt debugging

## Facets
- artifact type: library
- maturity: active
- function: security, compiler, developer-tools
- domain: security, reverse-engineering, developer-tools, windows
- platform: windows, cpp, c
- tags: obfuscation, compile-time, macro-header, anti-debugging, control-flow, tinycc, ctf, anti-decompilation
