I need to encrypt and decrypt a querystring in ASP.NET.

The querystring might look something like this:

http://www.mysite.com/report.aspx?id=12345&year=2008

How do I go about encrypting the entire querystring so that it looks something like the following?

http://www.mysite.com/report.aspx?crypt=asldjfaf32as98df8a

And then, of course, how to I decrypt it? What's the best encryption to use for something like this? TripleDES?
