mail-html5

Whiteout Mail is an easy to use email client with integrated OpenPGP encryption written in pure JavaScript. Download the official version under whiteout.io.

Privacy and Security

• We take the privacy of your data very seriously. Messages are encrypted end-to-end using the OpenPGP protocol. This means that only you and your correspondents can read your mail.

• The client talks directly via IMAP/SMTP to your mail server. Your messages and private PGP key are stored encrypted on your computer and are never sent to our our servers.

• The app is deployed as a Chrome Packaged App with auditable static versions in order to prevent problems with host-based security. It uses raw TCP sockets to communicate with the mail server.

• Mail server SSL certificates are pinned under src/ca/ in order to protect against SSL stripping and other man in the middle attacks.

• Content Security Policy (CSP) is enforced to prevent against injection attacks.

• The code is still under heavy development and is not yet recommended for production use. That being said, we have done multiple code audits and penetration tests (which will be published regularly once all reported vulnerabilities are fixed).

Reporting bugs and feature requests

• We will launch a bug bounty program later on for independant security researchers. If you find any security vulnerabilities, don't hesitate to contact us security@whiteout.io.

• You can also just create an issue on GitHub if you're missing a feature or just want to give us feedback. It would be much appreciated!

Testing

You can download a prebuilt bundle under releases or build your own from source:

npm install && grunt

This builds the Chrome Packaged App bundle DEV.zip which can be installed under chrome://extensions in developer mode.

Run the unit tests locally:

npm test
