After last year’s revelations about U.S. Internet surveillance raised interest in privacy tools, Google and Yahoo both announced they were working on software to let people who use their e-mail services easily exchange encrypted messages.
Now a prototype browser extension called ShadowCrypt, made by researchers at the University of California, Berkeley, and the University of Maryland, goes even further. It makes it easy to send and receive encrypted text on Twitter, Facebook, or any other website. ShadowCrypt was created to show that strong encryption could be made both simple to use and compatible with any of the popular services.
