Encrypt your Linux with LUKS, like seriously. (lemmy.ml)

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.

Sigh. I said i compress with AES-256. I compress my files with the compression that encrypts it. Just as the screenshot shows. (Compression+AES-256) I'm the OP of this post. Give me more credit. I know they are two different things. I think you just didn't get what I was trying to say

I said i compress with AES-256

To avoid confusion you could say, "along with", or fully say, "I encrypt with AES-256 as I compress, in one step".

It's not necessarily about what you know, but about what readers will understand. (For example, someone who doesn't know better might read what you wrote and think there is some way to compress using AES-256 and go down a rabbit hole.)

I understood what you meant, I was just pointing out that what you said was incorrect. Even in your reply you said

I compress my files with the compression that encrypts it.

Which is still not entirely correct. The compression is not doing any encrypting. They are two separate processes that the tool you are using is presenting as a single step for convenience. You seem to know what you are talking about, and I happen to know about cryptography, but as someone else in the thread mentioned not everyone knows how these things work. If we are trying to spread knowledge and tips in this community (like your post is doing) then I just saw this as an opportunity to clarify something that was incorrect. Not for your benefit, but for others.
