From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

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.

It does give me a result so I do have "aes". How can I use it?

We're talking an Intel i5-8350U. it has 16GBs of ram and 500GB of SSD.

That's pretty much my ThinkPad's Specs. Fine for almost all stuff I have to do on the go (expect CAD, don't try to run BricsCAD on the thing, it'll make you go crazy.)

I use full disk encryption on it, as on all my other devices, and it's fine, speed-wise. The SSD is NVME, not SATA, but I doubt the performance impact would be noticeable on a SATA SSD if that's what you've got.

mine's m.2 too. I tried systemd-homed, as of now it doesn't work as it should. Next I'll try disk/partition one but it'd be great to encrypt when sleeping, it's fine if it's hibernation

Full disk encryption always seemed the most sensible to me, but I'm not sure whether that needs to be decrypted after hibernation.
