Hamachi is a zero-configuration virtual private networking application. In other words Hamachi is a program that allows you to arrange multiple computers into their own secure network just as if they were connected by a physical network cable.

Hamachi gives you LAN over the Internet. Virtually any application that works over local/home networks can also be used over Hamachi networks. Think - Windows File Sharing, iTunes, Remote Desktop, Remote Assistance or even gaming. All fully encrypted, authenticated and peer-to-peer.

Hamachi is a UDP-based virtual private networking system. Its peers utilize the help of a 3rd node called mediation server to locate each other and to boot strap the connection between themselves. The connection itself is direct and once it's established no traffic flows through our servers.
