This code snippet demonstrates a simple yet effective string obfuscation technique using a combination of XOR, NOT, and ADD operations.

StringObfuscationTechnique.cpp

// White Knight Labs - Offensive Development Course
// String Obfuscation

#include <iostream>
#include <string>

// Function to apply XOR, then NOT, and finally ADD 1 for obfuscation
std::string obfuscateString(const std::string& input) {
    std::string output = input;

    for (char& c : output) {
        c = ~((c ^ 0xAA) + 1); // Obfuscate: XOR with 0xAA, ADD 1, then NOT
    }

    return output;
}

// Function to reverse the obfuscation process
std::string deobfuscateString(const std::string& input) {
    std::string output = input;

    for (char& c : output) {
        c = ((~c) - 1) ^ 0xAA; // Deobfuscate: NOT, then SUBTRACT 1, finally XOR with 0xAA
    }

    return output;
}

int main() {
    const std::string secretName = "OpenProcess";
    
    // Obfuscating the string
    std::string obfuscatedSecretName = obfuscateString(secretName);
    std::cout << "Obfuscated: " << obfuscatedSecretName << std::endl;

    // Deobfuscating the string
    std::string deobfuscatedSecretName = deobfuscateString(obfuscatedSecretName);
    std::cout << "Deobfuscated: " << deobfuscatedSecretName << std::endl;

    return 0;
