You haven't convinced me yet. I clearly stated "unless there is suspicion of
fraud". I don't think the police will ever have any interest in archives of
my daily schedules or projects and if they do, I don't mind frankly. As
long as they don't mirror it somewhere on the World Wide Web...

As long as I know I have done nothing wrong, why encrypt anything? I have
never once encrypted an E-mail message (apart from testing purposes, file
encryption likewise) although I sign all my outgoing messages. One would
argue that due to such practices, any encrypted message would trigger
suspicion. The authorities would clearly dread the day when every single
message gets encrypted.
