Encrypting user data on a locked BlackBerry device

If you or a BlackBerry® device user turns on content protection, you or the user can configure a locked BlackBerry device to encrypt stored user data and data that the locked BlackBerry device receives. When you or a user turns on content protection, a locked BlackBerry device is designed to use AES-256 encryption to encrypt stored data and an ECC public key to encrypt data that the locked BlackBerry device receives.

For example, the locked BlackBerry device uses content protection to encrypt the following items:
  • subject, location, meeting organizer, attendees, and any notes in all appointments or meeting requests
  • all contact information in the contact list except for the contact title and category
  • subject, email addresses of intended recipients, message body, and attachments in all email messages
  • title and information that is included in the body of a note for all memos (also known as posted messages)
  • subject and all information that is included in the body of tasks (also known as posted all day appointments)
  • if you use software tokens, contents of the .sdtid file seed that is stored in flash memory
  • all data that is associated with third-party applications that a user installs on the BlackBerry device
  • in the BlackBerry® Browser, content that web sites or third-party applications push to the BlackBerry device, any web sites that the user saves on the BlackBerry device, and the browser cache
  • all text that replaces the text automatically that the user types on the BlackBerry device

You can change the Content Protection of Contact List IT policy rule to Required to prevent the user from turning off content protection for the contact list on the BlackBerry device. If you change the Content Protection of Contact List IT policy rule to Required, the BlackBerry device does not permit call display and does not share contacts over a Bluetooth® connection when the BlackBerry device is locked.
