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.

How old are we talking? If the CPU is >10 years old and/or some kind of ARM, it may not have hardware encryption acceleration, which means it'll happen in software. I did that once, it was horrible. lscpu |grep -i aes should probably tell you what you need to know.

If you don't have hardware encryption you can use --cipher xchacha20,aes-adiantum option when running cryptsetup to make it way faster than standard aes cipher in software.
