Data protection is all the rage these days, and you can’t be too careful. TrueCrypt is an open source alternative to a number of encryption programs out there.  Actually the program is based on E4M (Encryption for the Masses) released in 1997 and discontinued in 2000.In order to store encrypted data TrueCrypt uses system volumes, the program basically creates a password protected and encrypted volume. If you provide the right password the volume is unlocked and you can use it as any other volume on your computer.

The program has a number of encryption algorithms you can use including; AES, Serpent and Twofish. All of the encryption algorithms are standards with AES being the most widespread one. If you want an extra layer of security it’s possible to create volumes that requires two-factor authentication using a keyfile. In order to unlock the volume both a password and a special keyfile is needed. Creating a new volume is done using a simple and easy wizard, almost any user can do it. Mounting a volume (which needs to be done every time you restart the computer or dismounts the volume) is also easy.  It’s a matter of choosing a volume file and clicking “mount” .  It is entirely possible to have 250 GB of data or more encrypted and use it as any other normal volume, you can even install programs on your encrypted volume.

TrueCrypt has the ability to run in traveler mode, which means that the program does not have to be installed on the OS it runs. This means that it is possible to take TrueCrypt with you on trips using a USB-stick, so you can bring business secrets on the road without having to worry about the data getting into the wrong hands.

The program also comes with a number of language packs, as always with Open Source software these kind of packs differ in quality and translation. Also with a fairly straightforward program like TrueCrypt there is no need for language packs.
