No idea if there's a simpler way but that's how I do it and it works, hope this helps.ĮDIT: This, of course, stores the vendor's key in you computer, which, in case you're not using something like a liveUSB or virtual machine to do your "SR stuff", I don't know if you're confortable with, but you can always delete and re-import the key each time you need it. A list with the keys you have in your computer pops up, select the vendors key, unselect the "Add To Recipients" option at the bottom-right and hit OK.Ĭopy the encrypted text, even the -BEGIN/END PGP MESSAGE- lines, paste it on SR and send it to the vendor. Write the message in TextEdit, select the text, right-click it to open the context-menu > Services > OpenPGP: Encrypt Selection. To send a message to the vendor (typically your address):

You'll then see a list on the right, find a section called Text and select everything that begins with OpenPGP. On the window that pops up select Keyboard Shortcuts if it's not already selected. Now that you have the vendor's key, click GPG Keychain Acess on the app menu bar (not sure how that's called, it's the top bar that changes accordingly to the app you're in), select "Services" and then "Services Preferences" from the menu. To explore the Keychain Access User Guide, click Table of Contents at the top of the page, or enter a word or phrase in the search field. You can use Keychain Access to manage these certificates. Open PGP Keychain Access, click Import, select the file with the vendor's key. To protect your computer, macOS uses digital certificates to verify the identity of the websites, servers, and other entities you communicate with.

Access the vendor's profile, copy his PGP key to a plain-text file (with TextEdit for example) and save it.
