How can you secure/encrypt your querystring in asp.net?

Question

I was wondering how you could encrypt/decrypt your querystring in a simple asp.net page? some values need to be passed between different pages but the querystring cannot be chan

Answer 1

How about adding the value you need to the Viewstate? Viewstate can encrypted and validated for you.

ViewState["myKey"] = "myValue";

and then later

string myValue = ViewState["myKey"]

To enable encryption:

<%@Page ViewStateEncryptionMode="Always" %>

or
