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.
