This looks like a great project. From what I can glean from a quick scan of the PDF is that CryptDB acts as a proxy encrypting/decrypting information as it flows to and from the database. It would be great not to have to worry about enforcing encryption on the application end. Does anyone have any experience with this? I wonder what kind of performance hit you take by running everything through this.
