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.

Is anyone here using their hardware TPM chips for credentials? (lemmy.world)

I'm curious about the possible uses of the hardware Trusted Protection Module for automatic login or transfer encryption. I'm not really looking to solve anything or pry. I'm just curious about the use cases as I'm exploring network attached storage and to a lesser extent self hosting. I see a lot of places where public private keys are generated and wonder why I don't see people mention generating the public key from TPM where the private key is never accessible at all.

The key is only released into ram, so unless the thief can read content from ram they cannot easily decrypt your disk. And most common thief probably do not have that ability.

That being said, you do need a login password to prevent the thief straight up booting into your OS and copy everything using the file manager...

One of the advantage of using TPM with FDE, is that you can use a much longer random password. If I dont use TPM I am forced to use a password I can remember, which is likely the same password I use somewhere else. This means if someone close to me stole my laptop, they will have reasonable chance of guessing my password.
