[OC] Graveyard — Dead simple encryption

After discovering Tomb, and a few personal issues with it, I decided to write a very similar program that doesn't require root access and compiles to a single binary: Graveyard.

Additional information and source code: GitHub.

Also, sorry about the ugly terminal colors, I recently just switched to Artix and haven't gotten around to making everything look amazing.

Edit: Cleaned up some stuff

It looks like the key-derivation function used here is just a single iteration of sha256 followed by truncating.

I'm not a security expert, but I'm pretty sure that's insecure.

Consider using PBKDF2 or Argon2.

Gosh, I've really messed up. Fixing immediately, thank you for bring this to my attention -- and I apologize to all y'all.

Again, I'm not a security expert, so maybe your original version was fine for this use case.

But since dedicated password-based key derivation functions exist, you should probably stick to one of those instead of rolling your own.

Thanks for fixing this quickly!

I haven't used tomb and I don't think I really have a usecase for this, but I respect the on-brand command aliases.

This is very interesting. I've bookmarked it, to play around with it later. Thanks!

What DE are you using? As very little provide vertical bars and for my UWQHD that would be good.

Not a desktop environment, Hyprland. The bar is a custom Waybar.
