crypto加密

需要自己下载crypto-js.js引入

<script src="js/crypto-js.js" type="text/javascript" charset="utf-8"></script>
<script type="text/javascript">
  //解析url参数
    function GetQueryString(name) {
        var reg = new RegExp("(^|&)" + name + "=([^&]*)(&|$)", "i");
        var r = window.location.search.substr(1).match(reg);
        if (r != null) return decodeURI(r[2]);
        return "";
    }
    var d = GetQueryString("d");
    var c = GetQueryString("c");
