About encrypting data on your smartphone
When encryption for data on your BlackBerry smartphone is turned on, your smartphone uses a private key to
encrypt data as it is stored on your smartphone, including data that your smartphone receives when it's locked.
Your smartphone decrypts data as you access it.
You can set encryption to include or exclude your contacts. If you turn on encryption for contacts and you receive a
call when your smartphone is locked, the caller name doesn't appear on the screen.
If you use a smart card certificate for authentication, depending on the smart card, you might also be able to use
one of your smart card certificates to provide two-factor encryption. In order to access the encrypted content, you
must provide your smartphone password and also connect your smartphone to your smart card reader.
When you lock your smartphone, an open lock indicator appears at the top of the screen to indicate that your
smartphone is in the process of securing your data, which includes deleting a copy of the private key from the
temporary smartphone memory. A lock indicator appears at the top of the screen when your smartphone has
deleted the key.
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.
