A new breed of relatively easy-to-use encryption and security services like Silent Circle have started popping up ever since Snowden made his revelations last year. One of the newest additions to that growing list is a Chrome browser extension called ShadowCrypt, which encrypts emails, Facebook status updates, tweets and other messages you send and post on social media. Once you've installed it, you'll need to generate an encryption key for every website you use or for every email you send. You'll then have to give those keys to people you want to share your posts with (they also need to be ShadowCrypt users, of course), otherwise all they'll see are garbled letter and number strings like the tweet below.
