To be fair, I think if the instructions mention to import the key from a site like Keybase like Sparrow does, I think it's fine. Most important thing is to not import the public key from the same site you received everything else and I think if people just follow instructions, they automatically do that.
It just makes me feel uneasy if people are not aware that this is important. The why's and so on.

like @DarthCoin say - education is key 🔑

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.
reply
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? 👀

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

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.ascand software is namedelectrum-4.5.3.dmg. This means the software was signed. - Sparrow: Signature is named
sparrow-1.8.2-manifest.txt.ascand software is namedSparrow-1.8.2-x86_64.dmg. This means that the software was not signed butSparrow-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 :)
