A PHP version of Packer, JavaScript obfuscation library originally created by Dean Edwards, ported to PHP by Nicolas Martin. Packed for composer and slightly extended by Thomas Lutz.

Usage (slightly changed from previous used implementation!)

<?php
require 'vendor/autoload.php';

$js = file_get_contents('test.js');

/*
 * params of the constructor :
 * $script:           the JavaScript to pack, string.
 * $encoding:         level of encoding, int or string :
 *                    0,10,62,95 or 'None', 'Numeric', 'Normal', 'High ASCII'.
 *                    default: 62 ('Normal').
 * $fastDecode:       include the fast decoder in the packed result, boolean.
 *                    default: true.
 * $specialChars:     if you have flagged your private and local variables
 *                    in the script, boolean.

// $packer = new Tholu\Packer\Packer($script, $encoding, $fastDecode, $specialChars, $removeSemicolons, $encryptionKey);
$packer = new Tholu\Packer\Packer($js, 'Normal', true, false, true, 'SOMEKEY');
$packed_js = $packer->pack();
echo $packed_js;

// Define the following variable before running the unpacking script
// var UNPACK_KEY = 'SOMEKEY';

Encription

Define the following variable before running the unpacking script. Encryption key is WEB by default, and is automatically added if UNPACK_KEY is undefined.

Encryption is not secured, and is used to hide variable names or the nature of the script.

var UNPACK_KEY = 'SOMEKEY';
