    Prabhu Raja has it nailed very well except that viewstate is not secure - it looks scrambled but that's just base64 encoding, and so is easily readable.  (A good viewstate reader was released some time ago by pluralsight)

    While adding the two lines below to web.config will go some way to actually encrypting the viewstate, it can still be cracked with not too much difficulty:  

    <pages enableViewStateMac="true" />

    <machineKey validation="3DES" />
