DNSCrypt is a piece of lightweight software that everyone should use to boost online privacy and security. It works by encrypting all DNS traffic between the user and OpenDNS, preventing any spying, spoofing or man-in-the-middle attacks.
It should be of particular interest to you if you frequently surf the web on open Wifi networks at coffee shops, airports, hotel lobbies, and the like. These types of public networks are notoriously insecure, and make it easy for cyber criminals and ISPs alike to see what you’re doing online and spy, spoof and conduct Man in the Middle attacks.
DNSCrypt encrypts, or hides, the communication between your computer or tablet and Open DNS servers while you’re browsing the Web. What?! You are not using OpenDNS servers? OpenDNS can help speed up your Internet service, make it more reliable, and improve your security.
Currently as of this writing, only available for the Mac, a Windows version is on the way:
