This makes a world of difference. I know many people may know of it but may not actually do it. It Protects your files in case your computer is ever stolen and prevents alphabet agencies from just brute forcing into your Laptop or whatever.

I found that Limine (bootloader) has the fastest decryption when paired with LUKS at least for my laptop.

If your computer isn't encrypted I could make a live USB of a distro, plug it into your computer, boot, and view your files on your hard drive. Completely bypassing your Login manager. If your computer is encrypted I could not. Use a strong password and different from your login

Benefits of Using LUKS with GRUB Enhanced Security

  • Data Protection: LUKS (Linux Unified Key Setup) encrypts disk partitions, ensuring that data remains secure even if the physical device is stolen.
  • Full Disk Encryption: It can encrypt the entire disk, including sensitive files and swap space, preventing unauthorized access to confidential information.

Compatibility with GRUB

  • Unlocking from Bootloader: GRUB can unlock LUKS-encrypted partitions using the cryptomount command, allowing the system to boot securely without exposing sensitive data.
  • Support for LVM: When combined with Logical Volume Management (LVM), LUKS allows for flexible partition management while maintaining encryption.

Yeah thanks pal. It helps you from someone who doesn't know your password. You all give the most extreme examples. That example applies to biometrics, normal passwords without encryption, bank pins, etc. What was the point of saying it? What technology would help you from that

I was actually largely agreeing with you, but responding to the bit where you said:

It Protects your files in case your computer is ever stolen and prevents alphabet agencies from just brute forcing into your Laptop or whatever.

It'll stop alphabet agencies from brute forcing it, sure, but that's not how they would approach extracting the information.

I see ~~~you've~~~ the mod has deleted this comment thread though, so it's unlikely anyone else will see it.

As to your question about what technology would stop it, I think you may need to think differently as no technology will stop a determined enough opponent torturing you for a password, but they're much more likely to attempt a malware style attack against you to skip all that bother. So countermeasures would involve a well locked down system (think about things like SELinux with MLS enabled and using VMs to isolate processes) and good information hygiene practices to reduce the risk of infection and the risk of it spreading if you are infected.
