PHP中的Sagepay表单提交参数

我需要多少参数才能通过表单ULR，它可以与sagepay支付网关交互。以下参数是我在表单url中传递的参数，但我遇到以下错误：

错误：

  Error number: 
    5068
    Error message: 
    The encryption method is not supported by this protocol version.

<form name='sagepay' action='{$pm_sagepay_url}' method='post' onsubmit='this.submit.disabled=true;return true;'>
        <input type='hidden' name='VPSProtocol'  value='3.00'>
        <input type='hidden' name='TxType' value= 'PAYMENT'>

        <input type='hidden' name='no_shipping' value='1'>
        <input type='hidden' name='no_note' value='1'>
        <input type='hidden' name='rm' value='2'>
        <input type='hidden' name='invoice' value='{$order->order_id}'>
        <div align='right'>
        <input type='submit' value='{!pay!}' name='submit2' alt='{!sagepay_pay!}' >
        </div>
      </form>";

我无法连接sagepay服务器支付。我对sagepay支付的配置完全陌生

有人可以告诉我需要传递多少个参数，它们是什么？ 如何加密值，然后传递值

代码：

添加到表单中的信息需要加密。最好使用以下指南：

另外，这个家伙已经为我得到的主表单发送的表单制作了一个基本脚本。它是成功页面，我无法工作，但我现在有了，所以如果你被卡住了，请给我一个叫喊
