DNSCrypt

DNSCrypt is a lightweight software application whose purpose is to help you protect your online privacy and security by encrypting all DNS traffic between the user and OpenDNS.

Although the OpenDNS service has gained its reputation on the market as one of the leaders in providing protection against phishing attacks, malware, botnets, on PCs, laptops, and tablets, the underlying DNS protocol proved not to be so secure as thought when the Kaminsky Vulnerability was detected.

Vulnerabilities in the DNS protocol usually rely on the so-called “last mile,” which represents the portion of your Internet connection between your computer and ISP (Internet Service Provider).

DNSCrypt ensures that the “last mile” of the DNS traffic is encrypted, thus offering you constant protection against man-in-the-middle attacks and snooping of DNS traffic by ISPs.

This unobtrusive tool runs quietly in the system tray without affecting your work. When called upon, it reveals only a few configuration settings to tinker with.

DNSCrypt gives you the possibility to activate or deactivate its functions, enable or disable OpenDNS, as well as enable the "DNSCrypt over TCP/443" function in case you have a firewall or other third-party tools that manage your packets.

Whether or not you are informed about eavesdropping and man-in-the-middle attacks, you can rely on DNSCryp for automatically turning regular DNS traffic into an encrypted one for improving your online security and privacy. The simple-to-configure parameters, which can be easily selected or deselected, can be tweaked by beginners and professionals alike.
