The only remaining weak point is that someone with physical

access to the client hard drive might turn off the client
741
computer, read the OpenPGP keys directly from the hard drive,
742
and communicate with the server. To safeguard against this, the
743
server is supposed to notice the client disappearing and stop
744
giving out the encrypted data. Therefore, it is important to
