How to install and use GPG Suite to encrypt email with Apple Mail


In in the present day’s world, safety and privateness are key. You have enterprise and private data you should transmit or share, and doing so with out first encrypting mentioned data is a danger. If you utilize a Linux machine, working with varied encryption instruments is extremely easy. You can set up the likes of OpenPGP from the usual repositories and simply use it from the command line or from inside apps like Thunderbird.

But what if macOS is your platform of alternative? What do you do? You have a number of choices, one in all which is to put in the GPG Suite of instruments. This explicit software program will set up GPGMail (an open supply plugin for Apple Mail), GPG Keychain (an open supply utility for macOS that permits you to handle OpenPGP keys), GPG Services (a plugin that brings GPG to just about any Mac utility), and MacGPG (the underlying engine for the GPG Suite). I will present you how one can get this open supply app put in and use it with the likes of Apple Mail.

I will likely be demonstrating on macOS High Sierra.

Signing and encrypting electronic mail

One of the explanation why I decide to make use of the GPG Suite on Mac is as a result of it integrates seamlessly with Apple Mail. There isn’t any must manually encrypt/decrypt electronic mail, utilizing keyboard shortcuts. However, as a way to encrypt an electronic mail to a contact, you’ll have to import their public key into GPG. To do that, both have them ship their public key to you or obtain it from one of many many public keyservers (if that is an choice to your contact). Once you have got the file in your drive, open GPG, click on Import, find the downloaded file, and click on Open. The public key will then be imported into GPG and is able to use.

With the general public key in place, open up Apple Mail and compose an electronic mail to the contact. You ought to see three new objects within the window (Figure C).

Make certain OpenPGP is chosen within the inexperienced drop-down. Compose the message as you usually would, after which click on both (or each) the Sign and Encrypt buttons to the correct of the Subject line. When you click on Send, you’ll be prompted for the GPG password you created if you generated your keypair. Type that and click on OK. Your electronic mail will likely be despatched, totally encrypted, due to GPG.

One notice on sending the e-mail. I might recommend unchecking the field for Save in Keychain. If you permit the password to be saved in your keychain, anybody that has entry to your machine might then ship an encrypted electronic mail from you. To that finish, don’t save your GPG password within the keychain.

You’re GPG good to go

And that is all there may be to utilizing GPG with Apple Mail. You can now simply ship encrypted mail to contacts with related public GPG keys, and decrypt incoming mail from contacts which have your GPG public key. It’s straightforward, safe, and dependable. Let your Mac and the GPG Suite stop your delicate data from falling into the fallacious arms.
