Available as a free download for Mac OS X, with Windows and Linux support coming next year, DNSCrypt wraps all DNS traffic between you and your DNS provider with encryption – this portion of internet traffic is commonly referred to as the “last mile”.

This “last mile” is often seen as the most vulnerable part of the internet’s infrastructure, where unscrupulous individuals with know-how and intent can eavesdrop or spy on users’ activity. Places like coffee shops and restaurants that offer unsecured internet access are particularly vulnerable to such “man-in-the-middle” attacks.

OpenDNS has stated that DNSCrypt’s code will be open-sourced in the near future.
