Crypt_Xtea documentation
------------------------
$Id$

The Crypt_Xtea package is a simple class to enable XTEA encryption on
sites where e.g. the mcrypt module is not installed.
The original C code on which this class is based was found at
from http://vader.brad.ac.uk/tea/source.shtml#new_ansi
Currently to be found at: http://www.simonshepherd.supanet.com/source.shtml#new_ansi

Use of the class is fairly straightforward:

<?php
	require_once 'Crypt/Xtea.php';

	$data = 'abcdefghijklmnopqrstuvwxyz';
	$key = '0123456789abcdef';

	$crypt = new Crypt_Xtea();
	$encrypted = $crypt->encrypt($data, $key);
	$decrypted = $crypt->encrypt($encrypt, $key);
?>

The output of both the encrypt() and decrypt() functions is a binary
string.

For your convenience a PHPUnit test class and test script have been
installed in the PEAR tests directory. To use it, check the Makefile
or try:

	make profile test

In version 1.1 a major bug in doing signed/unsigned calculations was
fixed after reports on the class not working on a Mac (thanks to
David Costa). Due to the fix the encryption/decryption process is now
relatively slow. Please check whether the amounts of data you want to
encrypt are relatively small, otherwise I'd suggest using the mcrypt
module.
Something went wrong with that request. Please try again.
