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.

It scares me. What if the chip dies? How am I gonna be able to get my stuff? I don't fully understand how it works, but where is the encryption saved? On the chip itself or somewhere else?

You can have backup keys, but if you don't have that then your data is gone.

Encryption key is stored in the TPM chip.

Ok this is scary. Lol Unless you have those backup keys then it's a bit better.
