Encryption 贝宝加密购物车数据

我用的是ExpressIonEngine，还有一个简单的商务模块，它不能提供我想要的

创建了我需要的所有东西，但我想改进它，所以cart中的所有东西都应该加密，这样就没有人可以更改DOM或其他东西了…：

下面是我正在加密的示例数组，但当我将表单提交到PayPal Sandbox时，我得到的错误是：我们无法解密证书id

形式如下：

    <form action="https://www.sandbox.paypal.com/cgi-bin/webscr" method="post">
    <input type="hidden" name="cmd" value="_s-xclick">

尝试了两种加密方式

ExpressionEngine函数加密\u数据。这很好，但只适用于一种产品，并直接添加到PayPal购物车。当我将上述数组中的数据传递给同一个加密函数时，PayPal无法解密证书id？！ 试过也从同一个问题中起作用。。。PayPal无法解密证书id。 我知道一切都是有效的，因为原生EE函数是有效的。 谁能帮我一个忙，建议我怎么办

提前谢谢

工作，只需交换证书参数
