Linux: How to encrypt your data on hard drives, USB sticks, etc.

Encrypting removable devices (USB flash drives, external hard drives, etc) provides a method to guarantee data security in the event of loss, theft or confiscation.

Ubuntu can quickly encrypt USB flash drives and external hard drives. You’ll be prompted for your passphrase each time you connect the drive to your computer – your private data will be secure, even if you misplace the drive.

In case you will loose your USB stick, all data stored on it will be lost and what is more important they will be most likely in hands of some other person which will then have an access to your private information and use this information in any way s/he sees fit.
