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.

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 not a slow laptop. I've been daily driving worse for years.
To protect the data from random thief just browsing through the files I still use ecryptfs. It only encrypts the home directory, and the keys are derived from my accounts password, so no extra hassle.
The encryption is weak by the current standards, and wouldn't stop a determined attacker, but it's 100% better than nothing, and I've never noticed any performance problems.
I'm not planning on putting information on my laptop that I don't have to. Speed for a bit of security sounds good. I'll look into
ecryptfs. And also into boot time, lots of you are screaming at me that it's a fast laptop. what howYou said you're on Arch, you'll want to go through their docs which are solid: https://wiki.archlinux.org/title/Dm-crypt/Encrypting_an_entire_system
That is absolutely not a slow laptop. If it takes a long time to boot there must be something wrong. I have a similar system that takes about ten seconds to boot.
Anyways, like others said, LVM with LUKS is the simplest. It uses your hardware to quickly decrypt the drive on boot. While it is running access to your data is protected by your login manager or lock screen.
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.
