encryptionclass's Introduction

#PHP encryptionClass

##Feature

This class offers a wrapper for the php5-mcrypt module that helps you encrypting and decrypting data. The encrypted data can be returned in binary or hexadecimal form.

##Installation

###Installing the extension

This class needs the php5-mcrypt module which is really easy to install via apt-get or aptitude:

sudo apt-get install php5-mcrypt
sudo apacht2ctl -k restart #if you use apache (you shouldn't ... use nginx!)

You're done! The php5 mcrypt module is installed and ready to be used. If you have problems installing the module check out http://www.php.net/manual/en/mcrypt.setup.php

###Configuring the script

For real security you should change the encryption key! You'll find it within the class file encryption.class.php.

...
	CONST DEFAULT_KEY = 'e2bf5a831914c';
...

##Usage

just require the class file and start encrypting:

<?
	require 'encryption.class.php';
	
	$string = Encryption::encrypt('encrypt me');
	echo $string; #should display "794af027bf97b9532b9ec0da3dffecc11d9a6a97b08a1775"
?>

Decrypting is as easy as encrypting:

<?
	require 'encryption.class.php';
	
	$string = Encryption::decrypt('ec762103b818704154a5ee13bb641c935986d3e03991301f');
	echo $string; #should display "decrypt me"
?>
