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.

EndeavourOS encrypted partition (lemm.ee)

I installed endeavourOS 2 days ago and then, the next day, there was a newnrelease of endeavourOS. It's supposed to have better encryption. Is it possible to upgrade encryption on Linux? An unrelated question: is it possible to change the password of an encrypted partition? I'm a beginner, so please explain your magical commands.

GRUB works just fine with LUKS2 these days. There is no need to switch bootloaders.

Apparently there's still some limitations, according to the Arch Wiki:

Initial LUKS2 support was added to GRUB 2.06, but with several limitations that are only partially addressed in GRUB 2.12rc1. See GRUB bug #55093.

Since GRUB 2.12rc1, grub-install can create a core image to unlock LUKS2. However, it only supports PBKDF2, not Argon2.

Argon2id (cryptsetup default) and Argon2i PBKDFs are not supported (GRUB bug #59409), only PBKDF2 is.

There is this patch, although I have not tested it myself. There is always cryptsetup luksAddKey --pbkdf pbkdf2.

That patch looks promising. But I wouldn't recommend PBKDF2, I mean if you're going to go thru the trouble of converting to LUKS2 for stronger encryption, might as well go for Argon2.
