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 are too are worried about security when it comes to online transfers, use Hamachi instead. This handy tool lets you connect two computers via the 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 interface that enables you to create personal safe networks in just a couple of steps. At first sight, it all looks very easy to use. Plus your connection is conveniently protected by an AES-256 algorithm.
Complications arise later on when trying to share files between computers: you'll have to do it through network sharing on Windows because it's not a feature Hamachi itself supports. In the end, I have to admit we were unable to share files over Hamachi during our tests – you know how stubborn Windows folder sharing configuration can get. Oh well, at least we could have a chat – a very safe one, of course.

RealPlayer has always enabled you to play RealAudio (*.ra) and RealMedia (*.ram) files.
Now, with RealPlayer, you can:
RealPlayer for personal use includes audio CD burning capabilities, DVR-style playback buffering, multimedia search, Internet radio, a jukebox-style file library, an embedded web browser (using Microsoft Internet Explorer), and the ability to transfer media to a number of portable devices, including Apple's iPod, MP3 players, and Windows Media devices.
Since version 11, RealPlayer also includes Flash Video support, DVD, SVCD, VCD burning and video recording (DRM is supported).
This freeware program promises to encrypt all your Internet connections, but since most public wi-fi access points in the U.S. are open, it's a bit hard to gauge Hotspot Shield's effectiveness. However, the connection itself is a bit wonky.
Once the program is installed, it creates an HTML link on your desktop. Double-clicking on it will open the application in your Web browser, and you'll be taken to a page detailing your Connection Status, IP Address, Server Address, Bytes sent and received, and the duration of the connection. Hotspot Shield is ad supported, so you'll get a big banner ad that lives at the top of every Web page, too. Closing the tab with the app's control panel doesn't disconnect the shield, though: for that, or to reload the control panel, you have to go through the green shield icon that gets loaded into your system tray. Also, there's a 5 GB transfer limit.
