User Guide Security Encryption About file encryption File encryption is designed to protect files that you store in the BlackBerry® device memory and on a media card that can be inserted in your device. You can encrypt the files in the device memory and on your media card using an encryption key that your device generates, your device password, or both. If you encrypt the files using an encryption key that your device generates, you can only access the files on your media card when the media card is inserted in your device. If you encrypt the files using your device password, you can access the files on your media card in any device that you insert your media card into, as long as you know the password for the device.

When content protection is turned on, your device uses a private key to encrypt data as it is stored on the device, including data that your device receives when it is locked. Your device decrypts data as you access it. You can set content protection to include or exclude your contacts. If you turn on content protection for contacts and you receive a call when the device is locked, the caller name does not appear on the screen. When you lock your device, an open lock indicator appears in the device status section of the screen to indicate that your device is deleting a copy of the private key from the temporary device memory. A lock indicator appears when the device has deleted the key. 237
