DNSCrypt is a piece of lightweight software 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.

DNS is one of the fundamental building blocks of the Internet.  It's used any time you visit a website, send an email, have an IM conversation or do anything else online.  While OpenDNS has provided world-class security using DNS for years, the underlying DNS protocol has not been secure enough for our comfort. 

Some of the underlying foundations of the DNS protocol are inherently weak  -- particularly in the "last mile."  The "last mile" is the portion of your Internet connection between your computer and your ISP.  DNSCrypt is our way of securing the "last mile" of DNS traffic and resolving (no pun intended) an entire class of serious security concerns with the DNS protocol.

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.
