Javascript encryption that match with PHP decryption : <p>I have the php code as below, and I want to create a Javascript functions that work the same as the php code below. Also, the data that encrypted in Javascript can also decrypt in php. 
`</p>

<pre><code>&lt;?php
class Security {
    public static function encrypt($input, $key) {
        $size = mcrypt_get_block_size(MCRYPT_RIJNDAEL_128, MCRYPT_MODE_ECB); 
        $input = Security::pkcs5_pad($input, $size); 
        $td = mcrypt_module_open(MCRYPT_RIJNDAEL_128, '', MCRYPT_MODE_ECB, ''); 
        $iv = mcrypt_create_iv (mcrypt_enc_get_iv_size($td), MCRYPT_RAND); 
        mcrypt_generic_init($td, $key, $iv); 
        $data = mcrypt_generic($td, $input); 
        mcrypt_generic_deinit($td); 
        mcrypt_module_close($td); 
        $data = base64_encode($data); 
        return $data; 
    } 
    private static function pkcs5_pad ($text, $blocksize) { 
        $pad = $blocksize - (strlen($text) % $blocksize); 
        return $text . str_repeat(chr($pad), $pad); 
    } 
    public static function decrypt($sStr, $sKey) {
        $decrypted= mcrypt_decrypt(
            MCRYPT_RIJNDAEL_128,
            $sKey, 
            base64_decode($sStr), 
            MCRYPT_MODE_ECB
        );
        $dec_s = strlen($decrypted); 
        $padding = ord($decrypted[$dec_s-1]); 
        $decrypted = substr($decrypted, 0, -$padding);
        return $decrypted;
    }   
}
