While DNSCrypt works with OpenDNS’s service alone, the company has released the specification and software as open source.

#LIST OF OPENDNS DNSCRYPT FREE#
(Some security experts are critical of the company’s policy of redirecting invalid domain-name entries to a Google search page from which it derives advertising revenue curiously, Google, which also offers a free alternative DNS service, does not.) It automatically fixes common typos, changing. But over the last few years those ISPs have improved their operations in response, OpenDNS added more services to entice users, some free (like anti-phishing filtering), and some paid (like filtering and usage reporting). OpenDNS came into being because the DNS servers at so many ISPs were slow and unreliable it was (and is) a free and more efficient alternative to other DNS servers. (You can set your system to always point to OpenDNS or another service, like Wi-Fi, but otherwise the server addresses are provided when the network router assigns a local address to your computer or device.) (Whew.) DNSCrypt forces DNS look-ups to go through OpenDNS instead of DNS servers operated by your own or a coffeeshop’s Internet service provider (ISP). The results are sent back to the resolver.

com root, for instance), which then finally hands off to the DNS server that manages information for a given domain. (In OS X, they’re found in the Network preference pane for each adapter.) That DNS server in turn passes the request up a chain of higher-level servers (to the. When a software client makes a DNS request, your computer consults a DNS resolver in the operating system, which then passes that query on to one of the DNS servers listed in its TCP/IP settings. If client software is connecting to a normal website, unprotected email server, or other Internet service, DNSCrypt keeps that lookup accurate as well, defeating efforts by so-called evil twins and other hotspot and networking spoofing techniques. This protects you from spoofing of servers that are protected by SSL as well as servers that aren’t so well protected. So when your computer says it wants to go to for which the DNS server should return an IP address of 1.2.3.4, a poisoned value of 5.6.7.8 could come back instead.Īs you might guess from the name, DNSCrypt encrypts this stage of the DNS client-server negotiation, so it’s impervious to that sort of chicanery. That creates a gap that can be exploited by substituting “poisoned” values for legitimate ones in DNS requests. Software clients that want to make Net connections must request those names in a plain text query that isn’t protected against tampering. They do so to give site operators the flexibility to move servers to different domains or to have multiple IP addresses respond to the same domain name. The CAs hand out a certificate with just the text of the server or domain name. Unfortunately, there’s a flaw in the system: One step in the validation process isn’t protected cryptographically. Those lists are built into operating systems (Mac OS X’s can be viewed via Keychain Access) and some browsers (Firefox being the primary example). These CAs provide digital documents to a site operator that are bound to a domain name () or a specific host-domain combination (A client can validate a server’s documents by checking their digital signatures against a list of trusted CAs.
