Convert PHP function to AS3

I need the decryption function below converted into AS3. ## Deliverables I need the following PHP function converted to AS3: function _decrypt($buffer, $key) { $decrypted = ""; $k2 = $key; $k2 = $k2 * 3; for ($i = 0; $i < strlen($buffer); $i += 4) { $s = substr($buffer, $i, 4); list($i2) = array_values(unpack("V", $s)); // little endian $i2 = $i2 ^ $k2; $s2 = pack("V", $i2); $decrypted .= $s2; } $decrypted = strrev($decrypted); return $decrypted; } To test your decryption, you will need to do the following: Write an SWF that calls the following script and decodes the result: [login to view URL]{any number} The decrypted result will be an encrypted XML formatted file. I am including the [login to view URL] file and the XML file it is encoding and returning.
