# xxtea

Implementation of the [corrected Block TEA](https://en.wikipedia.org/wiki/XXTEA) encryption algorithm in modern C++. 

It focuses on encrypting strings but it can be easily modified to encrypt binary data (take a look at the `encode` and `decode` functions).

This is a header only library so you just need to copy `xxtea.hpp` to your src folder and `#include` it.

## Usage

```cpp

#include 

#include "xxtea.hpp"

int main() {

  std::string secret{"super secret string"};

  

  auto encrypted = xxtea::encrypt(test, "hunter2");

  // encrypted is a std::vector, you can serialize however you want (an example of that is in the xxtea-php.cpp file)

  // if your password is less than 128 bits it will be padded

  

  std::cout << xxtea::decrypt(encrypted, "hunter2") << '\n';

  

  return 0;

}

```

## PHP extension

There's also a PHP extension inside xxtea-php, you can compile it using CMake. To be able to compile it you must have [PHP-CPP](https://github.com/CopernicaMarketingSoftware/PHP-CPP) installed.

Once you have PHP-CPP installed build and install the PHP extension is very simple: 

```bash

make

sudo make install

# enable it on your php installation eg: 

sudo cp xxtea.ini /usr/local/etc/php/conf.d/

```

And you're done
