[edit] How-To :: Alter/remove the peer-to-peer encryption key.

Enabling a peer-to-peer encryption key on BES is an effective way to secure PIN messages and/or BlackBerry Messenger messages sent between two Blackberry devices. When an encryption key is set, PIN and BB Messenger messages will only be able to be sent between two devices on the same BES.

To alter the peer-to-peer encryption key settings:

1. Open BlackBerry Manager.

2. Highlight the Domain in the left pane.

3. Choose the Global tab at the top of the right-pane.

4. Expand the Service Control and Customization section in the right pane.

5. Click the Update Peer-to-Peer Encryption Key link in the right pane.

6. Either set, or remove the Peer-to-peer encryption key depending on your requirements.
