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?

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.

let me do more practice to verify this newly learned skills 🥁

0 sats \ 0 replies \ @ek OP 24 Feb

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 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:

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.
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 :)
