您不应将敏感信息作为查询字符串传递.我可以看到您正在传递用户ID，密码，手机号码等.
这是一个糟糕的设计

您可以使用以下选项之一:

1.使用回发
2.在会话中存储数据
3.在viewstate中存储数据
4.利用Cookie

如果要加密和解密，则可以从以下URL使用HTTPModule:

http://madskristensen.net/post/HttpModule-for-query-string-encryption.aspx

You should not pass the sensitive information as a querystring. I can see that you are passing user id, password, mobile number etc.
This is a bad design

You can use one of the options:

1. use a Postback
2. Storing data in sessions
3. storing data in viewstate
4. making use of cookies

If you want encrypt and decrypt, you can use HTTPModule from the following URL:

http://madskristensen.net/post/HttpModule-for-query-string-encryption.aspx

byte[] data = new byte[DATA_SIZE];
byte[] result;
SHA512 shaM = new SHA512Managed();
result = shaM.ComputeHash("User");

这将给SHA512计算哈希值.

看看下面要使用的其他功能.

或者尝试使用会话值，以便在重定向时不要将值发布到您的url中.这很简单
只需使用lik

this wil giv ur SHA512 computed hash value.

take a look at the following to use other function.

Or try using the session values, so that when redirecting you dont hav to post the values into ur url. Which is simple
simply use it lik

<pre>Session["User"]="xxxx";
Session["ps"]="xxxx";
...
Response.Redirect("http://xxx.xxx.com/WebServiceSMS.aspx");
