Obfuscator
This project is an LLVM obfuscator compiler and machine code obfuscator designed to protect C++ applications from decompilation and static analysis. It functions as an LLVM pass framework that transforms intermediate representation into complex machine code to prevent the reverse engineering of program logic.
The tool implements binary security hardening and anti-reverse engineering measures to protect intellectual property. It achieves this by modifying the compilation pipeline to hide original control flow and data structures.
The transformation process includes control-flow flattening, the injection of opaque predicates, and instruction substitution. It further complicates the binary through dead code insertion and the modification of machine instructions while preserving original execution semantics.
Features
- Obfuscation Pass Frameworks - Functions as an LLVM pass framework that transforms intermediate representation to protect program logic.
- Control Flow Flattening - Provides control-flow flattening to hide logical branches using a centralized dispatcher loop.
- LLVM-Based Compilers - Provides a compiler toolchain based on LLVM that generates obfuscated machine code.
