Hamachi is a small program used to create one VPN connection between two or more devices that have the software running. This creates a virtual local area network (LAN) between the connected PCs, which can therefore interact with each other as if they were on the same local area network.
It can be used for functions that are otherwise reserved for devices on the same network, such as access to shared files, use of a network printer, etc. It can also be used as your own private (and free) VPN connection that will effectively secure your internet connection against hackers and debugging if, for example, you uses open WiFi or other forms of insecure network.
Hamachi also popular for gaming, where VPN the connection allows users to connect over LAN, despite not being physically on the same local area network. It is eg. become particularly popular with Minecraft players, where it is used to connect to LAN servers over the Internet, but can also be used for many other games.
At "normal" VPN Services are the provider that provides dedicated servers that subscribers can connect to the Internet through. Hamachi works differently, because it is an application that can work as both VPN server and client, which is why the users themselves create VPN the servers and allow others to connect to them. The connection is secured with a password so that unauthorized persons cannot access the virtual local area network.
The software is extremely simple to use, and is intended as a "zero configuration" solution that requires no technical skill from the users. It lives up to a great extent, because you really have to do nothing but follow very few and logical instructions when starting the program, to either start or connect to a server. VPN the connection is encrypted with an 256 bit AES encryption algorithm, so it is practically impossible to break.
The program is available for Windows, Mac OS X, and Linux (beta), and is free to download and use, so you can only maximize the connection of five devices at the same time. If you need a larger number of connections, there are various premium subscriptions where you can pay for it.
Although Hamachi uses VPNThen it is not always a good substitute for a real one VPN service, since the server's IP address is public. Internet connections made via Hamachi VPNSo, it can easily be tracked - at least until the person who has run the server.
However, Hamachi can be a nice and completely secure solution if you are connected to the network via an open WiFi or other insecure Internet connection in e.g. the airport, on the train, in a café or the like. If you make sure you have a Hamachi server running on a PC at home and connect to it, you can effectively secure your internet connection against hackers and monitoring that way. One should not expect to be able to stream Netflix in 4K on the connection, but it can easily be used to check emails, Facebook etc.
In addition to the virtual LAN functionality, there are also some practical tools such as text chat and file transfer.
