Encrypt whole system?
(sh.itjust.works)
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.
There is a way for just your home folder to be encrypted, Linux Mint has it as an option.
Looks like they use eCryptFS. Never heard of it before so thats neat. I can see using it on systems where you can't reinstall the system with Dm-crypt but it most cases I suspect Dm-crypt is a better alternative.
Idk if its faster or slower than Dm-crypt.
