Researchers have developed code exploiting several vulnerabilities in PGP (including GPG) for email. In response, EFF’s current recommendation is to disable PGP integration in email clients.

Disabling PGP decryption in Apple Mail requires deleting a “bundle” file used by the application. Your existing keys will remain available on your machine.

People who use mail plugins for encryption have no idea how they work; the result is a false sense of security.

1. First, click the Mail icon in the dock.

2. Click “Mail” in the menu bar on the top of the screen, and select “Quit Mail.” This is to make sure it’s shut down completely before we continue.

3. Click the Finder icon in the Dock.

4. Click the “Go” menu in the menu bar on the top of the screen, and select “Go to Folder…”

5. This will open the “Go to Folder” window. Type this exact text: /Library/Mail/Bundles

5. At this point, you may see a folder with the “GPGMail.mailbundle” file. (If you don’t, return to step two, and in step 3 instead type exactly ~/Library/Mail/Bundles. You can type the ~ (tilde) character by holding shift and pressing the ` key, located directly below Esc on most keyboards.)

6. Move the file “GPGMail.mailbundle” to the trash, either by dragging it to the trash icon on the dock or by right-clicking it and selecting 'Move to Trash.'

6. At this point, you may be prompted to type your macOS administrator password. Type it in, and hit the “enter” key.

You may see the file deletion dialogue displayed on the screen.

Once the GPGMail.mailbundle file is in your trash, your emails will not be automatically decrypted in Apple Mail.

Note that you will instead see the email as a Mail Attachment file paired with the encrypted.asc file. You can download this asc file and use it to decrypt the message on the command line.

Note on Usage

This guide is recommended for a specific use case, in which you only use Thunderbird as a tool for email encryption, while reading and sending unencrypted email through their webmail interface in a browser or through a different client.

You can still use Thunderbird as your regular mail client, and we recommend it if you prefer to download your email to a secure device instead of leaving it in the servers of your email provider. For this latter case, we will recommend alternative settings in the relevant sections.

Thunderbird is a free and open source, cross-platform email client for sending, receiving and storing email. An email client is an application that lets you download and manage your messages — from multiple accounts with multiple providers — without a browser.

Gnu Privacy Guard (GPG) is free and open source software capable of encrypting, decrypting and digitally signing messages and files. It also generates and manages the public and private keys needed to do so.

Enigmail Enigmail is an add-on for Thunderbird to encrypt, decrypt and sign emails, and to manage PGP keys.

1.0 Things you should know before you start

You will need at least one email account to use Thunderbird. If you want to create a new account to use with Thunderbird, you can find a list of privacy-conscious email services here.

Like all email clients, Thunderbird makes a copy of your messages available on your computer. This includes the emails you send as well as those you receive. As a result, it is particularly important that you have full-disk encryption enabled if you intend to use Thunderbird. To do so, check that FileVault2 is enabled before starting this guide.

Thunderbird cannot protect your device if you open malicious attachments or click on malicious links. Do not open unsolicited attachments and exercise caution when clicking on links that were sent to you by email. Learn how to Protect your device from Malware and Hackers.

In order to better protect the data in your computer, we highly recommend making sure that your device is encrypted. To do so, check that FileVault2 is enabled before starting this guide.

1.1 Other tools like Thunderbird

Thunderbird is available for GNU/Linux, Microsoft Windows and macOS. Securely managing multiple email accounts is a complex task, and we strongly recommend Thunderbird for this purpose. However, if you prefer to use an alternative we recommend the following free and open source tools:

Claws Mail is available for GNU Linux and Microsoft Windows
Sylpheed is available for macOS, GNU/Linux and Microsoft Windows
K9 Mail and OpenKeychain are available for Android
Mailpile is available for GNU/Linux (and should be available for Windows and macOS in the future).

The security advantages of Thunderbird are significant, particularly when compared to commercial alternatives like Microsoft Outlook.

2.1 Download and Install GPG Suite

In order to encrypt your emails, you will first need to download and install GPG Suite, the encryption manager that enables your computer to encrypt your emails.

Download GPG Suite by clicking the 'Download' button in GPG Suite website.
Check 'Save File' and click 'OK' in the prompt that pops up.
Once you have downloaded the file (which will be called GPG_Suite-YEAR.MONTH.dmg), verify it by following the below steps:
- Hover over 'SHA256' on the download page below the download button, to visualize a sequence of numbers and characters.
- On your machine, open a terminal
- Enter the command below in the terminal:
  $ shasum -a 256 /path/to/GPG_Suite-YEAR.MONTH.dmg
