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.

Encrypted hard drive asking for password every time (lemy.lol)

I recently switched to Linux (Zorin OS) and I selected "use ZFS and encrypt" during installation. Now before I can log in it asks me "please unlock disk keystore-rpool" and I have to type in the encryption password it before I'm able to get to the login screen.

Is there a way to do this automatically like with Windows or MacOS? Zorin has biometric login which is nice but this defeats the purpose especially because the encryption password is long and tedious to type in.

Also might TPM have anything to do with this?

EDIT: Based on the responses I have to assume some of you guys live in windowless underground bunkers sealed off with concrete because door locks "aren't secure against battering rams". Normal people don't need perfect encryption they just want to add an extra hurdle or two for the crackhead who steals the PC. I assumed Linux had a system similar to what Windows or MacOS has been doing for a decade but I am apparently wrong.

I recently dug into this because I accidentally trashed my wife’s OS which was encrypted with bitlocker. PITA btw and I couldn’t beat the encryption

Bitlocker encryption key hash is stored in 2 possible places. First is an unencrypted segment of the encrypted drive. This is bad because it’s pretty easy to read that hash and then decrypt the drive. The second place is on a Trusted Platform Module (TPM) which is a chip on the motherboard. This is better because it’s much more difficult to hack. It can be done but requires soldering on extra hardware to sniff the hash while the machine boots up. Might even be destructive… I’m not sure.

Either way a motivated attacker can decrypt the drive if they have physical access. For my personal machines, I wouldn’t care about this level of scrutiny at all.

Anyways you can see if any open source solutions support TPM.
