During the last few weeks I have been working on Goopg, a new extension for the Chrome and Chromium browser which allows one to sign and verify emails directly from the Gmail web page.

It consists mainly in two parts: an extension, which gets information from the Gmail web page, and a plugin (written in python) which silently verifies the emails, signs the outgoing messages and sends them via the Gmail APIs and a SMTP connection. For more information about the architecture, see the project documentation.

To install it you have to:

1. Install the Goopg extension from the Chrome web store
2. Install the plugin package using the following PPA:

sudo add-apt-repository ppa:team-goopg/goopg
sudo apt-get update
sudo apt-get install goopg-chromium

Install the package goopg-chrome if you use Chrome.

The project is Open Source, released under the GPL-3 license and it is not affiliated with Google.

Thanks to Alessio Treglia, Andrea Colangelo, Riccardo Padovani, Mattia Rizzolo for testing and to Paolo Rotolo for the icon.

Future works:

• Support to Firefox and to other browsers
• Support to other Operating System, like Mac/OSx
• Support to encryption/decryption
