我的工作在Dibs支付集成，但无法实现成功。所有的事情都在演示模式下工作良好，但当商家的ID提供给它，然后打开卡的细节形式之前，它给出了一个错误的""。数据已被篡改。Checksome是无效的". 我不知道这是什么。经过我的google搜索，我发现这是与MAC计算有关的东西，但如何在我的代码中计算MAC。我的整个支付类如下，所有注释。

这是我第一次做支付工作。请帮助我，因为安全是这里的主要关注点.Thanks in advance:)
Dibs允许MAC由两种算法计算算法的选择是由你。目前它可以处理MD5和SHA-1。Dibs推荐使用SHA-1，因为它提供了更好的安全性。
SHA-1(data¤cy&method&SecretKey&)
或
MD5(data¤cy&method&SecretKey&)
数据这里是包含购买金额和数量信息的字符串。
