FastXor is a C++ class that provides a fast XOR encryption method using SIMD instructions. It can be used to efficiently XOR data with a key.

Intrinsics Guide

• SIMD-based XOR encryption for improved performance.
• Supports XOR operation on arrays, vectors, and strings.
• Easy-to-use C++ class interface.

To use this package, you can clone the repository and compile it using a C++ compiler:

git clone https://github.com/NIR3X/FastXor.cpp
cd FastXor.cpp/sse2 # or /avx2
make

To use the FastXor class, include the "FastXor.h" header in your project and make sure to link against the appropriate libraries.

#include "FastXor.h"

// Your code...

// Example with vector<uint8_t>
std::vector<uint8_t> data = { /* your data */ };
std::vector<uint8_t> key = { /* your key */ };

CFastXor::Xor(data, key);

// Example with string
std::string strData = "YourStringData";
std::string strKey = "YourKey";

CFastXor::Xor(strData, strKey);

// Your code...
