Cutypie-Obfuscator is a C++ header-only library for string obfuscation and control flow for a static analysis disassembler tools like ida, binaryninja, ghidra and more. This library helps protect your code against reverse engineering by implementing runtime string encryption and compile-time control flow obfuscation.

✨ Features

• String Encryption: Compile-time string obfuscation
• Control Flow Obfuscation: Complex flow patterns in disassemblers
• Header-Only: Easy integration with no dependencies

✨ The Result:

How To Use

#include "cutypie_obfuscator.h"

int main() {
    // Initialize control flow obfuscation
    Initialize();

    // Encrypt strings at compile-time
    constexpr auto encrypted = C_OBF("Hello, World!");
    // Decrypt strings at run-time
    const auto decrypted = encrypted.decrypt();
    
    return 0;
}

Requirements

• C++17 or higher
• GCC, G++ or MSVC compiler (recommended)

Configuration

Disable Optimization First!!! In your Project Properties > C/C++ > Optimization > Whole Program Optimization = set to "No"

Set your custom secret key in the header file:

// Must be exactly 15 characters
constexpr char Secret_Key[] = "MySecretKey1234";

Set the Initialize Macro in the start of your int main() to enable control flow obfuscation

int main() {
    // Initialize control flow obfuscation
    Initialize();

Use encryption string if you want to:

constexpr auto encrypted = C_OBF("Hello, World!");

For Decryption (This process decrypt the string at runtime only):

const auto decrypted = encrypted.decrypt();
