Because of the potential vulnerabilities of software encryption, Kanguru strictly uses 256-bit AES hardware encryption for all Kanguru Defender secure USB flash drives, hard drives and solid state drives. Kanguru's hardware encrypted drives contain an "always-on" built-in random number generator that independently handles all of the security for the drive. When you plug the device into a USB port for the first time, a brief initialization set-up wizard will prompt you to assign a password for the device, along with a few simple questions of your preferences regarding features of the drive. Once you create your password, the encryption algorithms lock into place, and you can begin using your drive just as you would any other USB drive. The only difference you will notice is that you'll be required to enter your secure password when you plug the drive into a new machine to access your information.
