Simple, easy-to-use and effective PHP Encryption class. It's a standalone single file PHP class to use on your projects. It requires no dependencies or no framework.

You only need only one file:

• Encryption.php

You can run everything from the index.php file, see the file for usage.

// Include the class file
require 'Encryption.php';
// Set a secret key
const KEY = 'secretkey';
// Message string to encode
$message = 'Hello world';

$encoded_text = Encryption::Encode($message, KEY);
//@return d1pXc2dsYVBqQ0NrSkJ1Zy85RWprUT09

$decoded_text = Encryption::Decode($encoded_text, KEY);
//@return Hello world

• This code uses openssl for encrypt & decrypt data. See PHP Manual for more information.
• Default encryption method is AES-256-CBC. You can change it on Encryption.php file at line 14 & 29. Or you can enter it as thrid parameter on both static mathods.
