Not all vendors put their market name on the cert. The cert from a market seller like AvengingTurd (made up) will show up as user102 under certificates if they didnt name with their market username.
After I import a cert can I change the name? After a few weeks I forget which certname goes with which vendor.
Just go back to there profile and look at there PGP and see what there PGP name is. I don’t think you can change it on kleopatra, I tried when I was on windows a year ago and it didn’t let me. And I know GPG suite on Mac (which is what I use now) won’t let you. I hate when vendors don’t put there PGP name as there vendor name. Like why? lol Amazon4Drugs PGP name is “the Hershey” or some shit lol
You can use the command "gpg --edit-key" followed by that key's name to edit whatever you've imported. Once you've ran that run "adduid" to bring up the menu of things you can change. If you don't know the key's name run "gpg --list-keys" to find it. I hope that helps.
