Encrypted is not a boolean variable
Let's face it, encryption is a new thing, and you have to keep things simple so people can understand it.
But it frustrates me that most of the talk about encryption technology, law, policy, compliance, etc is always in terms of "encrypted" vs "unencrypted". Yeah, all your data should be encrypted. But that's the beginning of the discussion, not the end. Encryption is easy. Protecting data is hard.
