这是我的加密课程

define('KEY', '1234567891111111');
class crypto 
{
    //private static $key= 'DocT0r$t@y';
    public function encrypt ($payload) {
        $iv = mcrypt_create_iv(
            mcrypt_get_iv_size(MCRYPT_RIJNDAEL_128, MCRYPT_MODE_CBC),
            MCRYPT_DEV_URANDOM
        );
        //$iv = mcrypt_create_iv(IV_SIZE, MCRYPT_DEV_URANDOM);
        $crypt = mcrypt_encrypt(MCRYPT_RIJNDAEL_128, KEY, $payload, MCRYPT_MODE_CBC, $iv);
        $combo = $iv . $crypt;
        $garble = base64_encode($iv . $crypt);
        //return trim($garble,'�');
        return $garble
    }

    public function decrypt ($garble) {
        $combo = base64_decode($garble);
        $iv = substr($combo, 0, mcrypt_get_iv_size(MCRYPT_RIJNDAEL_128, MCRYPT_MODE_CBC));
        $crypt = substr($combo, mcrypt_get_iv_size(MCRYPT_RIJNDAEL_128, MCRYPT_MODE_CBC), strlen($combo));
        $payload = mcrypt_decrypt(MCRYPT_RIJNDAEL_128, KEY, $crypt, MCRYPT_MODE_CBC, $iv);
        //return trim($payload,'�');
        return $payload
    }
}

这就是我如何打电话给我的班级并检查出来

$e=crypto::encrypt($pwd);
        $d=crypto::decrypt($e);

        echo $e."   ".$d;

        if($d==$pwd)
            echo "<br>yes";
        else
            echo "<br>no";
        exit();

当我检查可能会在firebug输出显示我

(这里123是我想要加密/解密的文本)。 任何建议我做错了什么或为什么它是mot工作?
