Optionally we recommend to verify public keys. This KB-article explains how to verify and sign a key.

Import key from asc or txt file

If you receive a public key in from of an asc or txt file, to import the key, drag the file in question into GPG Keychain. Make sure to never use .rtf .odt .doc .docx files to transfer keys or OpenPGP messages as that will render the key or message invalid. Should you receive a public key in such format, ask the key owner to resend the key in asc or txt format.

Import key from text form

To import, select the entire key from

-----BEGIN PGP PUBLIC KEY BLOCK-----

to

-----END PGP PUBLIC KEY BLOCK-----

then copy (⌘C) and paste (⌘V) the information into GPG Keychain to import the key.
