Encrypt Querystring value

[robertfah]

Is there a way to encrypt a value that I set in the querystring?

I've got a page that passes an ID to another page to display details on that ID, but I don't want the user to see the obvious ?ID=888. Is there a way to encrypt that going to the other page, then decrypt it once I receive it on that other page?

Thanks!

Yes, there are various methods you could use. Check out the System.Cryptography class for more info.

you could also pass this information back and forth via session.
pros: don't need encryption.
cons: extra postbacks, page redirects and session maintaince to accomplish the same task.
