Encryption is a method of securing data by scrambling the bits of a computer's files so that they become illegible. The only method of reading the encrypted files is by decrypting them with a key; the key is unlocked with a password.

Benefits and key features

Whole disk encryption protects everything on a disk drive – including the operating system. Even files you may not know about that keep exact copies of data that you've been working on, such as temporary files are encrypted.

  • Data is protected while a computer is turned off or in sleep mode, as long as the hard disk is password protected.
  • Most useful on hardware that is likely to be lost or stolen (e.g., laptops and USB drives), but can be enabled on desktops as well.
  • A key recovery process is available for managed computers in the WIN.MIT.EDU domain in the event of a lost password.
  • The whole disk can be decrypted with the assistance of a local IT administrator.
  • Users who are not in the WIN.MIT.EDU domain must save their password and key in a safe place, such as LastPass.
  • Encryption does not protect a machine against malware.
