DNSCrypt is a lightweight software and works by encrypting all DNS traffic between the user and OpenDNS, preventing any spying, spoofing or man-in-the-middle attacks. “In the same way the SSL turns HTTP web traffic into HTTPS encrypted Web traffic, DNSCrypt turns regular DNS traffic into encrypted DNS traffic that is secure from eavesdropping and man-in-the-middle attacks”. It is true that the internet poses some very real security threats to computer users, even if they have protected their computer with good security solution. That means we need to build a few defenses ourselves, rather than completely rely on a single security solution to do this. I am sure OpenDNS’s DNSCrypt can do something good on this issue. DNSCrypt currently available for Mac users only. Interested users can get more details and download at source here.
