My laptop isn’t under my supervision most of the time. And I’d hate it if someone were to steal my SSD, or whole laptop even, when I’m not around. Is there a way to encrypt everything, but still keep the device in sleep, and unclock it without much delay. It’s a very slow laptop. So decryption on login isn’t viable, takes too long. While booting up also takes forever, so it needs to be in a “safe” state when simply logged out. Maybe a way that’s decrypt-on-demand?
I’m on Arch with KDE.
If you don’t have hardware encryption you can use
--cipher xchacha20,aes-adiantumoption when runningcryptsetupto make it way faster than standard aes cipher in software.
