The folks at OpenDNS just released a a new tool to encrypt DNS server traffic. In a few words it "DNSCrypt is a piece of lightweight software that boosts 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."I'm in China and have had nightmarish problems with DNS spoofing and poisoning so this tool is looking very useful to me.
It is currently Mac only.
