Algorithms that the BlackBerry Enterprise Solution uses to encrypt data

The BlackBerry Enterprise Solution uses AES or Triple DES as the symmetric key cryptographic algorithm for encrypting data. By default, the BlackBerry Enterprise Server uses the strongest algorithm that both the BlackBerry Enterprise Server and the BlackBerry device support for BlackBerry transport layer encryption.

If you configure the BlackBerry Enterprise Server to support AES and Triple DES, by default, the BlackBerry Enterprise Solution generates device transport keys using AES encryption. If a BlackBerry device uses BlackBerry Device Software version 3.7 or earlier or BlackBerry Desktop Software version 3.7 or earlier, the BlackBerry Enterprise Solution generates the device transport keys of the BlackBerry device using Triple DES.
