Free, open source disk encryption software TrueCrypt allows you to secure your thumb drive (among other things) so that you don’t need to worry about losing sensitive information if you lose that little drive.
- Creates a virtual encrypted disk within a file and mounts it as a real disk.
- Encrypts an entire hard disk partition or a device, such as USB flash drive.
- Encryption is automatic, real-time (on-the-fly) and transparent.
With TrueCrypt installed to AutoRun on your thumb drive, you just plug in your drive, enter your password, and work like you normally would. Unplug it, and anyone trying to use it again will need to enter your password before they can access any of your information.
