With the assistance of GPG Suite, Apple Mail can support OpenPGP encryption for secure communications. Learn how to import an OpenPGP public key into Apple Mail :
Before proceeding, ensure that you’ve installed GPG Suite and have configured your Mailfence account in Apple Mail. Additionally, confirm that you have exported the OpenPGP public key from your Mailfence web-interface or any other source.
- Open the GPG Keychain app, which is part of the GPG Suite you installed on your Mac.
- In the GPG Keychain menu at the top, click on Import.
- Several options are available to import the OpenPGP public key:
- Directly go to File in the menu bar and choose Import…. In the dialog box that appears, navigate to the saved location of your OpenPGP public key file, select it, and click Open.
- To discover keys online, click on Search Key Server in the toolbar. Then enter the email address or key ID of your OpenPGP public key and hit Search.
- GPG Keychain will display the details of the public key you’re about to import. Verify the validity of the OpenPGP public key by checking the fingerprint.
- Confirm the import by clicking Import. For public keys, you might see an indication like “Untrusted”. This is normal; you can decide to trust the key based on your personal verification of its authenticity.
The OpenPGP public key is now imported into GPG Keychain. You can use it to send encrypted emails to the respective contact using Apple Mail or to verify digital signatures from that individual.
