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