A2D JS框架

这次实现了JS端的DES加密与解密，并且C#端也能正确解析DES的密文（反之也实现了）

使用的代码如下，非常方便：

<script src="A2D.js" type="text/javascript"></script>
<script language="javascript" type="text/javascript">
        var msg = $.DES.encrypt("要研究mysql，最好的资源莫过于源码了，所以本人打算通过调试源码的方式来深入理解mysql的点点滴滴。");
        document.writeln(msg);
        document.writeln("<br />");
        document.writeln($.DES.decrypt(msg));
    </script>

 输出内容：

要研究mysql，最好的资源莫过于源码了，所以本人打算通过调试源码的方式来深入理解mysql的点点滴滴。

C#服务器端使用了js沙箱来运行A2D.js代码，因此能做到加密解密的一致性，如下：

public static class JSSecurity
    {
        public class MockWindow
        {
        }
        public class MockDocument
        {
        }

        public static string MainJSPath { get; set; }
        static MockWindow wnd = new MockWindow();
        static MockDocument doc = new MockDocument();

        public static string Encode(string plainText)
        {
            using (JavascriptContext context = new JavascriptContext())
            {
                context.SetParameter("window", wnd);
                context.SetParameter("document", doc);
                context.SetParameter("message", plainText);
                string js = File.ReadAllText(MainJSPath);
                js += @"
                            result = window.$.DES.encrypt(message);
";
                context.Run(js);
                string result = (string)context.GetParameter("result");
                return result;
            }
        }
        public static string Decode(string encryptedText)
        {
            using (JavascriptContext context = new JavascriptContext())
            {
                context.SetParameter("window", wnd);
                context.SetParameter("document", doc);
                context.SetParameter("encryptedMessage", encryptedText);
                string js = File.ReadAllText(MainJSPath);
                js += @"
                            result = window.$.DES.decrypt(encryptedMessage);
";
                context.Run(js);
                string result = (string)context.GetParameter("result");
                return result;
            }
        }
    }

真的很简单。

下面来看看Cookie的使用，加密了的，不是明文的，并且服务器端能够正确解析：

 <form action="WebForm1.aspx" method="post">
        <input type="button" onclick="javascript:onSetCookie();" value="set cookie(js des encrypt)" />
        <br />
        <input type="submit" value="Post" />
    </form>
    <script language="javascript" type="text/javascript">
        function onSetCookie() {
            $.Cookie.set("账号ID", "aaron.dai");
            alert($.Cookie.get("账号ID"));
        }
    </script>

当click按钮后，设置cookie；点Post按钮后，submit到webform1.aspx，让C#来解析cookie的明文：

protected void Page_Load(object sender, EventArgs e)
        {
            global::A2D.JSSecurity.MainJSPath = System.IO.Path.Combine(AppDomain.CurrentDomain.BaseDirectory, "A2D\A2D.js");

            foreach(string key in Request.Cookies.AllKeys)
            {
                Response.Write("key:"+key);
                Response.Write("<br />value:" + Request.Cookies[key].Value);
                Response.Write("<br />=====><br />");
                Response.Write("key:" + global::A2D.JSSecurity.Decode(key));
                Response.Write("<br />value:" + global::A2D.JSSecurity.Decode(Request.Cookies[key].Value));
            }
        }

just so easy.
