Whiteout Mail is an easy to use email client with integrated OpenPGP encryption written in pure JavaScript. Download the official version under [whiteout.io](http://whiteout.io).
* Messages are [encrypted end-to-end ](http://en.wikipedia.org/wiki/End-to-end_encryption) using the [OpenPGP](http://en.wikipedia.org/wiki/Pretty_Good_Privacy) standard. This means that only you and the recipient can read your mail. Your messages and private PGP key are stored encrypted on your computer.
* Users have the option to use [encrypted private key sync](https://blog.whiteout.io/2014/07/07/secure-pgp-key-sync-a-proposal/) if they want to use Whiteout on multiple devices.
* Like most native email clients whiteout mail uses raw [TCP sockets](http://developer.chrome.com/apps/socket.html) to communicate directly with your mail server via IMAP/SMTP.
* Mail server [SSL certificates are pinned](http://security.stackexchange.com/questions/29988/what-is-certificate-pinning) in order to protect against SSL certificate forgery and other man in the middle attacks.
* The app is deployed as a [Chrome Packaged App](https://developer.chrome.com/apps/about_apps.html) with [auditable static versions](https://github.com/whiteout-io/mail-html5/releases) in order to prevent [problems with host-based security](http://tonyarcieri.com/whats-wrong-with-webcrypto).
* [Content Security Policy (CSP)](http://www.html5rocks.com/en/tutorials/security/content-security-policy/) is enforced to prevent against injection attacks.
* 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](mailto:security@whiteout.io).
* You can also just create an [issue](https://github.com/whiteout-io/mail-html5/issues) on GitHub if you're missing a feature or just want to give us feedback. It would be much appreciated!
You can download a prebuilt bundle under [releases](https://github.com/whiteout-io/mail-html5/releases) or build your own from source (requires [node.js](http://nodejs.org/download/), [grunt](http://gruntjs.com/getting-started#installing-the-cli) and [sass](http://sass-lang.com/install)):
This will download all dependencies, run the tests and build the Chrome Packaged App bundle **DEV.zip** which can be installed under [chrome://extensions](chrome://extensions) in developer mode.
Then visit [http://localhost:8580/dist/chrome.html#/desktop](http://localhost:8580/dist/chrome.html#/desktop) for front-end code or [http://localhost:8580/test/unit/](http://localhost:8580/test/unit/) to test JavaScript changes. You can also start a watch task so you don't have rebuild everytime you make a change:
We work together with existing open source projects wherever possible and contribute any changes we make back upstream. Many of theses libraries are licensed under an open source license. Here are some of them:
