It just makes me feel uneasy if people are not aware that this is important.

Haha yes. Like a secret key hidden in plain sight.

is my understanding correct?
the logic behind this is the dev uses his private key to sign the signature ( asc ) which then hash the software.

Yes
You just summarized my post with a few words haha
Wait, no. The dev signs the software (or whatever). The signature IS the hash "encrypted" with the private key.

hmmmm, I need to do more practice to understand it better, and I still don't get the part when you need to do the checksum or not? 👀

madness 😂
so if abcd.dmg.asc with abcd.dmg - no need. but abcdfrfsve.dmg.asc with abcd.dmg - need.
did you use a new key to sign that?

No, I just used gpg --clearsign. I just hoped it would pick the right key haha.
Due to the markdown formatting, it might get tricky, but you should be able to use go to #437477/edit to see the raw formatting.
edit: Oh no, it picked a wrong GPG secret key 🙈
Will post new message with my ekzyis@ekzyis.com GPG key

I, @ek, author of The Curious Case of Digital Signatures, a post that received 20k+ sats on SN, the first of his nym, hereby vouch for the GPG skills of @Natalia, the first of her nym (on SN at least), a stacker with multiple good posts on SN (see profile), one even in the all-time top posts (at the time of writing this).
May the force of verifying digital signatures be with her forever.

I still don't get the part when you need to do the checksum or not? 👀
No worries! This means I didn't explain well enough (among other things) 👀
You need to do the checksum stuff when the name of the signature file without .asc at the end is not the same as the software you downloaded.
Examples:
  1. Electrum: Signature is named electrum-4.5.3.dmg.asc and software is named electrum-4.5.3.dmg. This means the software was signed.
  2. Sparrow: Signature is named sparrow-1.8.2-manifest.txt.asc and software is named Sparrow-1.8.2-x86_64.dmg. This means that the software was not signed but Sparrow-1.8.2-manifest.txt.
So it depends on what was signed. You can sign anything. Like I just signed this message. Try to verify the signature :)
