Secure Messaging Scorecard

> This is version 1.0 of our scorecard; it is out of date, and is preserved here for purely historical reasons. Please visit Surveillance Self-Defense if you're looking for recommendations on specific tools to use to ensure your privacy and security while we work on writing an updated guide to secure messaging. Again, you should not use this scorecard to evaluate the security of any of the listed tools, as many of them have been changed since the scorecard was last updated (some for the better, some for the worse).
