Hamachi allows the creation of Virtual Private Networks via the Internet.

Thanks to Internet connections becoming faster and better, we can share data and documents more simply. Caution should be used when sharing data between computers via the Internet because these data can be "stolen" by someone with sufficient knowledge. In these situations arises the concept of Virtual Private Network (VPN) software, which encrypts data flowing between computers that are part of this Network.

Hamachi allows VPN network creation on the Internet. This means that we can securely connect to other computers and share all kinds of data without worrying about security. We can say that this program creates a LAN (Local Area Network) that can connect computers located in any part of the globe. Instead of having a LAN connected with RJ45 cables, we will have a LAN connection using the Internet connection infrastructure. All data of the LAN created with Hamachi will be encrypted and "travel" safely.

We can use this program to create a new network or join an existing one. This program is often used to share files securely between computers connected through the Internet. These online play games allow connections from the local area, or share peripherals, such as printers, webcams, etc., via the Internet.

The usage is simple. For example, if we want to create a Local Area Network (LAN) to playing online a video game, we have to open the program and create a new network. To create a new network, we have to assign it a name and password. Once we've created the network, we can provide our friends with the network ID and password. Our friends must install Hamachi and use the option to "Join an existing network," enter the network's ID and password that we have provided. Now, our friends and we are joined to the same network, so the only remaining thing is to enter the computer's IP in the video game that will act as a server. We can see our PC's IP in Hamachi's interface, next to the button "On/Off."

The program includes a chat tool that we can use to talk with the components of the network.

The free version of this program supports up to 5 computers connected to the same network. If we want to expand the number of computers per network, we need to acquire some of the subscriptions available on the program's official website. In addition, the paid version allows us to manage our network from a web browser and access them from any computer without having to install a Hamachi server.
