Why Test TrueCrypt?
TrueCrypt has been around as an OpenSource encryption tool for a few years. Its main application was the creation of so-called encrypted containers to store files in a secure manner. Containers can even be mounted as Windows drives in recent versions of the tool. With the introduction of TrueCrypt 6.0, the tool was given the ability to encrypt an existing Windows installation on the fly, which means adding the extra layer of security by encrypting the entire system drive or partition. In our tests, this worked really well. In fact, our positive experience was the impetus to write this article—we found subjectively that TrueCrypt wouldn’t even slow down your system despite real-time encryption and decryption of your entire system instance and data.
