GPGMail

GPGMail is a plugin for OS X's Mail.app, which let's you
send and receive secure, OpenPGP encrypted and signed messages.

Important

GPGMail currently doesn't support macOS Sierra (10.12). We're actively working on it. Follow us on Twitter for updates.

Visit our support page if you have questions or need help setting up your system and using GPGMail.

Localizations are done on Transifex.

Prerequisite

In order to use GPGMail you need to have GnuPG installed. You can either build your own version, use one from homebrew or find a packaged version for OS X at gpgtools.org

Build

Clone the repository

git clone https://github.com/GPGTools/GPGMail.git
cd GPGMail

Grab Dependencies

In order to communicate with GnuPG we use our own Objective-C framework called Libmacgpg. It's necessary to clone the Libmacgpg repository first, before building GPGMail.

cd Dependencies
git clone https://github.com/GPGTools/Libmacgpg.git
cd ..

Build

make

Install

Copy Libmacgpg.framework from Dependencies/Libmacgpg/build/Release/ to ~/Library/Frameworks.

After that copy the GPGMail.mailbundle file from build/Releases/GPGMail.mailbundle to ~/Libray/Mail/Bundles, re-start Mail.app and enjoy.

System Requirements

• Mac OS X >= 10.9 (macOS Sierra is not yet supported!)
• Libmacgpg
• GnuPG
