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.

Encrypt whole system? (sh.itjust.works)

My laptop isn't under my supervision most of the time. And I'd hate it if someone were to steal my SSD, or whole laptop even, when I'm not around. Is there a way to encrypt everything, but still keep the device in sleep, and unclock it without much delay. It's a very slow laptop. So decryption on login isn't viable, takes too long. While booting up also takes forever, so it needs to be in a "safe" state when simply logged out. Maybe a way that's decrypt-on-demand?

I'm on Arch with KDE.

Encrypting and decrypting are complex operations that requires a lot from the hardware. The resources needed to encrypt and decrypt is proportionally correlated with the amount of files you're encrypting and decrypting.

That said, there are some alternatives

  1. Encrypt the whole filesystem
  2. Encrypt only your home folder
  3. Encrypt only the files you wanna

There is an app, Vaults, that allows you to create vaults to easily encrypt and decrypt folders. Take a look on this app

ChatGPT, is that you?

Well, looks like now we cannot be helpful and polite that people call you ChatGPT

Sorry :(

(But seriously that formatting and phrasing was very very AI looking.)

[–] KLISHDFSDF@lemmy.ml 2 points 2 months ago

lets not forget AI was trained on human data. some people will "sound like AI" because they likely make up a big portion of its demographic training data.

Detectors say that you are human, you use multiple languages, and you are a moderator, but it feels like a 101 AI response. It's horrible that we're living in an era where you need to be careful about this. You were probably trying to format it nice, but I've only read this phrasing from AI.

But thanks for the answer, the home folder would probably be best. I don't want to think about it after setting it up. All my downloads and docs are there. I also feel like the whole filesystem would take forever for me to unlock/boot.

Are the detectors part for real or were you just kidding? 😲

Yes, I was, because I like to put my text well formated... I feel pain when I have to read bad formated texts, so I try to be as clean as possible

For home folder I think there is a better alternative, like systemd-homed or something like that

they got your back, why are you suprised?

Others also said systemd-homed. And it looks promising, I'll try it, but honestly I have no idea how to test it? From another user? From a liveboot usb?

Because I don't even knew that this kind of tool exists. And it was precise AF. I just got surprised/scared haha

About systemd-homed, I guess that liveusb will not work... I suggest you to try in a VM and everything going ok, you may try on another user on your pc

Oh, I think I'll wipe my laptop, and do it live. What I wanted to ask was how do I know if it's working?
