Random GPG key in my Laptop??? (lemmy.ml)

I was creating a new key for pass when I noticed a random expired GPG key assigned to a certain "Roderick van Domburg" in my list of keys. I don't know any Rodericks, and this laptop has been whipped clean.

Should I be concerned? How could this even happen???

The archlinux-keyring package will install a few gpg keys.

But also, the AUR also uses gpg keys to validate things.

Just searching the AUR for one of the repos that Jaffa linked to in another comment...

https://aur.archlinux.org/cgit/aur.git/tree/PKGBUILD?h=librespot

Here is the PKGBUILD. Note line 24:

validpgpkeys=('EC57B7376EAFF1A0BB56BB0187F5FDE8A56219F4') ## Roderick van Domberg

And I'm sure if you got through the AUR there are plenty of packages that use this

Many AUR helpers (like paru, or yay, etc), will either auto download these keys for you, or prompt you. Even if you were to build this pkgbuild by hand, unless you removed that line, it would require you to import the key for the makepkg to work. So "how does a fresh arch install wind up with GPG keys that I didn't manually import?" ... the answer is AUR helpers most likely (or you did it manually for a makepkg and just forgot).

It's also worth pointing out that GPG handles signing things, but also signature verification. These are all public keys in your system. Having public keys that have been used for signature verification is perfectly normal and kind of the point. If you had Roderick's private key that would be weird.
