"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

I like the KB307010 method because it is clean, single purposed and auditable.
You might want to consider whether the additional speed and level of security of the System.Security.Cryptography.AesCryptoServiceProvider makes it worth utilizing as an alternative to the DESCryptoServiceProvider used in that example.
