I think it would be valuable to create a signature on this key to make the output messages better. On macOS / linux this would look like

gpg --quick-lsign-key "29590362EC878A81FD3C202B52527BEDABE87984" || (gpg --quick-generate-key `whoami` && gpg --quick-lsign-key "29590362EC878A81FD3C202B52527BEDABE87984")

(tries to quick sign key; if we can't that probably means we don't have a private key, so generate one then re-sign)

On windows this can be done in kleopatra via the "certify key" option

if you certify the validation looks like

root@b0b541f146d6:/# gpg --verify dashcore-20.0.4-x86_64-apple-darwin.dmg.asc 
gpg: assuming signed data in 'dashcore-20.0.4-x86_64-apple-darwin.dmg'
gpg: Signature made Fri Jan 12 17:26:20 2024 UTC
gpg:                using RSA key 29590362EC878A81FD3C202B52527BEDABE87984
gpg: Good signature from "Pasta <[email protected]>" [full]

if you don't certify it looks like this; more scary as it kinda should be

I'm conflicted on this. More steps = less likely that someone is going to actually do it. I also don't like auto-creating a key for someone to avoid that message. Provided someone actually looks at the fingerprint, certifying doesn't actually make anything safer.

The Windows instructions in particular need more work anyway (they lag because none of us actually use Windows). I'd prefer to merge this small cleanup PR and leave the rest for a separate thing. My Kleopatra updates are actually from Linux because I figured they're at least more accurate than the outdated ones that were there before.

Edit: I added a note to Linux/Mac about signing the key
