PCWorld: TrueCrypt – Free, Reliable Encryption Utility
Encryption utilities that come with Windows 7 and some USB drives are all very well, but this one comes in versions for PC, Mac and Linux, making it a universal solution. Did we mention it’s free?
“Though encryption is a strong way to safeguard passwords, personal information, and other sensitive data, it can be confusing due to the acronyms and technobabble that surround the topic.
Many encryption utilities–such as the BitLocker feature in Windows 7 Ultimate, or the Rohos Mini Drive utility for protecting info on a thumb drive–are available. But my favorite tool covers all the bases: It’s free, it’s easy, it’s effective, and it works on all major operating systems. TrueCrypt lets you create virtual encrypted drives. Versions are available for Windows, Mac OS X, and Linux; if you install it on several machines running different OSs, you can open your encrypted files from a network share, thumb drive, or other shared storage device.”
