The correct order is hash then encrypt, exactly so you can't do that. Now I don't know if FileVault is doing this correctly, but hopefully it does. Edit: So two people have downvoted me without explanation. Is what I'm saying wrong?

You could also hash, encrypt, then hash again if you wanted extra integrity without decrypting. This is technically done with HTTPS through the TCP hash.
