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
Here is a project that will show you how to do symmetric encryption. http://www.codeproject.com/KB/security/SimpleEncryption.aspx
Dare I mention this, because it will create significant overhead, but you can post your information in the view state and use cross page posts to pass the information around:
