The P2P protocol is frequently used to exchange files and other data between users, but some people regard it as quite an insecure method.

If you too are worried about security when it comes to online transfers, use Hamachi instead. This handy tool lets you connect two computers via Internet by creating your own private network and protecting it with industry-standard encryption algorithms. This means that your communications will be safe from prying eyes at all times, creating a private channel between both computers.

Hamachi features a simple step-by step tutorial that launches the first time you use the program, showing you how to use the main functions. At first sight, it all looks very easy to use. Complications arise later on when trying to share files between computers: you'll need to have a user account with enough privileges in the target PC, or so it seemed in our testing, during which we were unable to share files due to right issues. Oh well, at least we could have a chat – a very safe one, of course.

Hamachi is a great solution to establish safe, private P2P connections between two computers; unfortunately it's not as easy to use as it seems at first sight.
