I downloaded the signature file next to the electrum download which I'm not sure about that if those are the right files in right order. I made a keypair but it mentions a private key?
 
"If you already have a private key that can be used to certify other people's keys, you can import it at this time."



I'm new to "cryptocurrency/Bitcoin" and I've needed to learn PGP encryption for anything in my life until now so any help is greatly appreciated more than one can realize lol.
