Chances are you have information on your mobile device(s) that you want to keep private or secure. Thankfully, protecting your personal and business information is easy with the free and open source encryption program TrueCrypt.
TrueCrypt is simple to use and the encryption is both transparent and done on-the-fly (i.e., in real time). You can use it to create a password-protected, virtual encrypted disk to store sensitive files and folders, and TrueCrypt can even encrypt entire disk partitions or external storage devices, such as USB flash drives.
So if you haven't done so already, download and install the latest TrueCrypt package for your operating system (the program works on Windows XP, Vista, Mac OS, and Linux). If you want to encrypt a USB flash drive, you can install the program directly to the USB drive.
