About file encryption
File encryption is designed to protect files that you store on your BlackBerry® device and on a media card that can be inserted
in your device. You can encrypt the files on your device 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.
