Looks like some html, nothing to decrypt really.. What are you trying to do?

This looks more like a key generated to help prevent xsrf attacks, no?

The viewstate of a page contains (as the name suggests) the state of a form. It fills in the form for you after a postback event.
Some googling tells me it's a base64 encoded string.

I'm just wondering in what scenario you need to decrypt it.
