Gpg suite for encypting mail app on mac2/24/2023 I’m going to show you how you can get this open source app installed and use it with the likes of Apple Mail. I will be demonstrating on macOS High Sierra. The first thing you must do is download and install the GPG Suite. Once you’ve downloaded the file, double-click on the download to mount the image. In the resulting popup ( Figure A), double-click on Install and walk through the installation wizard. Once installed, move the GPG Suite installer file to the trash and eject the desktop icon for the mounted image. SEE: Electronic communication policy (Tech Pro Research) Generating your keyĪs soon as the installation is complete, and you’ve moved the installer file to the trash, GPG will open, waiting for you to enter the necessary information to generate your GPG key pair ( Figure B).Įnter the required information and then click Advanced options. In this section, you can select your key type/length, add a comment, and change the expiration date. If you want your key to be permanent, uncheck Key expires, and click Generate Key. You will be instructed to work on your machine (typing, clicking, etc.) to generate entropy. Do this until you are prompted to upload your public key to the default GPG keyservers. If you don’t want to make this public key available for anyone to download, click No, Thanks!, and you’re ready to continue.

One of the reasons why I opt to use the GPG Suite on Mac is because it integrates seamlessly with Apple Mail. There is no need to manually encrypt/decrypt email, using keyboard shortcuts. However, in order to encrypt an email to a contact, you will have to import their public key into GPG. To do this, either have them send their public key to you or download it from one of the many public keyservers (if that’s an option for your contact). Once you have the file on your drive, open GPG, click Import, locate the downloaded file, and click Open. The public key will then be imported into GPG and is ready to use. With the public key in place, open up Apple Mail and compose an email to the contact. You should see three new objects in the window ( Figure C). Make sure OpenPGP is selected in the green drop-down. Compose the message as you normally would, and then click either (or both) the Sign and Encrypt buttons to the right of the Subject line. When you click Send, you will be prompted for the GPG password you created when you generated your keypair. Your email will be sent, fully encrypted, thanks to GPG. I would suggest unchecking the box for Save in Keychain.
