File encryption is a great way of keeping data secure, particularly on a USB drive or external hard drive. It renders the files unreadable without the decryption key. Usually the decryption key is very long, and derived from a password or passphrase that you choose.

Some anti-virus programs include encryption features, and recent versions of Windows have the BitLocker feature that allows you to encrypt your drive and access it with a password:

University of Otago staff must consult their departmental administration or IT support staff before using any file encryption software for University files. This is to ensure that business-critical files can be recovered if the employee is unavailable or if the decryption keys are lost.
