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.
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 doesn’t require any changes to domain names or how they work, it simply provides a method for securely encrypting communication between our customers and our DNS servers in our data centers.
