BitLocker is a hard drive encryption utility in Windows 7 and Vista, unfortunately it’s only available in Ultimate and Enterprise editions and not in XP at all. Today we take a look at TrueCrypt, which is a free utility that will enable encryption functionality to other versions.

TrueCrypt is a free Open Source disk encryption utility that works with Windows, Mac, and Linux. It allows you to encrypt an entire drive, partition or flash drive and ensure no one can access the data without the right password. It provides on-the-fly encryption and after the drive is encrypted you can continue to use everything like you normally would.
