""The way we encrypt messages before storing them is relatively unique. We only know of one commercial service, and one commercial product that will secure user data using asymmetric encryption before writing it to disk. Basically we generate public and private keys for the user and then encrypt the private key using a derivative of the plain text password. We then encrypt user messages using their public key before writing them to disk. (Alas, right now this is only available to paid users.)" http://possibility.com/LavabitArchitecture.html http://possibility.com/LavabitArchitecture.html
