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.
