问题描述

亲爱的所有人，

如何在不编写单独的类文件的情况下加密/解密查询字符串值.我使用了Server.HtmlEncode/Server.HtmlDecode和Server.UrlEncode/Server.UrlDecode.如下所示，但不起作用.

传递查询字符串值时:

Dear All,

How to encrypt / decrypt a query string value with out writing a seperate class file. I used Server.HtmlEncode/Server.HtmlDecode and Server.UrlEncode/Server.UrlDecode. Like below but not working.

When passing query string value :

string userId = "44";
Response.Redirect("~/Result.aspx?userId="+ Server.HtmlEncode(userId));

接收查询字符串值时:

When receiving query string value:

if(Requeset.QueryString["userId"]!=null)
{
    string UserId = Sever.HtmlDecode(Request.QueryString["userId"].ToString());
    // ------ here getting the data from database basing on this userId value.
}

我使用了HtmlEncode/Decode和UrlEncode/Decode，但是没有用.解决方案的网址链接中未加密userId.请任何人对此问题有任何想法.让我知道.

在此先感谢...

推荐答案

Dim encrypter As New MD5CryptoServiceProvider()
Dim b As Byte()
Dim encoder As New UTF8Encoding()
b = encrypter.ComputeHash(encoder.GetBytes(querysting))

我只知道您可以通过这种方式对字符串进行加密.....
