Hi,

I want to redirect to some page with querystring,and the querystring value should be in encrypted format and i want to decrypt that in codebehind

example:

function redirect(s, e)
{
   window.location.href = "Default2.aspx?Id=" + encrypt(5)+ "&No=" +encrypt( 5);
}

and in codebehind:

Dim id As String = Request.QueryString("Id").ToString()
        id = Decode(id)
Dim no As String = Request.QueryString("No").ToString()
        no= Decode(no)

Thanks in Advance
