If you're on the move regularly or your hard drive is accessible by third parties, it's always vulnerable to attack. One way to prevent possible compromises of your security is by encrypting data. TrueCrypt aims to do this by allowing you to encrypt data "on-the-fly". This means that data is automatically encrypted or decrypted immediately before they are loaded or saved without any input required from you. Nothing can be encrypted or decrypted without using the correct password or encryption keys. This encryption extends to entire file systems such as file names, folder names, file contents, free disk space etc. The good thing about this particular program is that it doesn't get in the way of you dragging and dropping files. Some encryption programmes that work on-the-fly prevent you from doing so easily or add a delay to the transfer but that's not the case with TrueCrypt. The other good thing is that TrueCrypt never saves any decrypted data to a disk – it only stores them temporarily in your RAM which is far more secure because when you restart Windows or turn off your computer, the volume will be dismounted and files stored in it will be inaccessible and still encrypted. The interface is a bit bland but at least it's simple enough to follow and not full of complicated encryption jargon. A very solid encryption tool although the fact that it's open source means that it's vulnerable to modification which could compromise encryptions.
