RKENC - Ragekill-Encrypt

RKENC is a lightweight AES encryption library. (It supports C.T.O aswell [Compile-Time-Obfuscation])

• It only requires cryptopp library.
• Supports multiple data types.

• string, int, bool, double, float, long, etc. are supported.
• Made for c++20

Platform:

• Cross-Platform. (macOS, Windows, Linux)
• If you intend to port it elsewhere, for example, IOS, you'd need to build cryptopp for IOS.

Features

• AES Encryption -> Cryptopp
• Type Support -> supports multiple data types.
• Lightweight -> single header, which is easy to understand.
• Anti-Debug -> Anti-Debugging built in for cross-platform.
• C.T.O(Compile-Time-Obfuscation) -> Using XOR for compile time obfuscation. P.S: I added C.T.O on a whim, it's probably not the best thing you could use for obfuscation. It would only deter skids and noobies. I'd recommend to remove it, and just use O-LLVM, which is an llvm obfuscator for clang.

Prequisites:

To use RKENC, you need to have the Crypto++ library installed. You can install it on Ubuntu using:

sudo apt-get install libcrypto++-dev

For Arch-Linux:

sudo pacman -S cryptopp

You will also need a cpp compiler that supports c++20, like g++ or clang. Both can be used. I use clang.

Example usage:

#include "rkenc.h"

int main() {
    RKENC::AESCRYPT rk;

    
    int normalInt = 42;
    std::string crypt = rk.encrypt(normalInt);
    std::cout << "Encrypted: " << crypt << std::endl;

    
    int decrypted = rk.decrypt<int>(crypt);
    std::cout << "Decrypted: " << crypt << std::endl;

    return 0;
}

Output:

Encrypted: G"��v��#B>��P��������9�~Z��t��]�{E�._

Decrypted: 42

Anti-Debugging (NEW):-

Output:-

Compiling:

Updates:

Soon. If there are any requests to update it, I will respond.

• Added anti-debugging mechanism for cross-platform
• Added C.T.O
