🔒 C++ String Obfuscator (XOR-Based)

✨ Features

• Compile-time XOR obfuscation of char[] and wchar_t[]
• Simple macro usage with automatic seed based on source line number
• Easy integration (just include one header)
• Runtime decryption + memory zeroization support

⚙️ How It Works Strings are XOR-encoded at compile time using a seed derived from the line number, then decoded at runtime using the same key. This helps evade static analysis and basic reverse engineering.

example usage ( c++ )

#include "obfuscator.h"

int main() {
    const char* secret = obfuscate("Hello, World!");
    const wchar_t* wide_secret = obfuscate_w(L"Sensitive WString");
    
    printf("Decrypted: %s\n", secret);
}

🔐 Overview obfuscate("string") Accepts a const char[] literal

• Obfuscates it using an XOR key derived from the line number

• Decrypts lazily at runtime when used

obfuscate_w(L"wstring")

• Accepts a const wchar_t[] wide string literal
• XOR-obfuscated at compile time
• Decrypted on demand

Internals (Header)

• XorString<N, Seed> : Template for narrow strings
• XorWString<N, Seed> : Template for wide strings
• xor_key(seed) : Generates a pseudo-random XOR key from the seed

const char* hidden = obfuscate("Secret123!");
