Figure 16-40 Enabling BitLocker Drive Encryption

Beyond A+

Aside from the tools available in Windows, you can find some excellent encryption tools readily downloadable. Arguably the best, most powerful of these tools is TrueCrypt.

TrueCrypt

TrueCrypt is an open-source disk encryption application with versions available for just about every operating system. You can use TrueCrypt to encrypt an entire partition or you can create an encrypted volume into which you can securely store data. The beauty of the encrypted volume is that it acts like a folder that you can move around or toss on a USB flash drive. You can take the volume to another system and, as long as you have the password and TrueCrypt installed on the other system, you can read the contents of the encrypted volume. If the thumb drive is big enough, you can even put a copy of TrueCrypt on it and run the program directly from the thumb drive, enabling you to read the contents of the encrypted volume—as long as you know the proper password.

TrueCrypt has some limitations, such as a lack of support for dynamic disks and some problems with multi-boot systems, but considering the price (free, though donations are cheerfully accepted) and the amazing power, it’s hard not to love the program. This discussion of TrueCrypt barely scratches the surface of what the application can do, so check it out at www.truecrypt.org. If you’re running Windows XP Home or Windows Vista Home Premium, you can’t get a better tool for securing your data.
