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.

[-] cbarrick@lemmy.world 2 points 1 year ago

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!

Love the colors. The yellow and pink are gorgeous

[-] hai@lemmy.ml 1 points 1 year ago

Thanks, here's the color scheme!

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.
