About TLS
The BlackBerry® Browser configuration is designed to use TLS or SSL to encrypt data that your device sends or receives over the Internet
through the BlackBerry Enterprise Server. Communication between your device and the BlackBerry Enterprise Server is encrypted using
Triple DES. Communication between the BlackBerry Enterprise Server and content servers is encrypted using SSL or TLS. To increase
security, you can set up TLS for HTTP connections between your device and the BlackBerry Enterprise Server and use Triple DES encryption
for all other communication between your device and the BlackBerry Enterprise Server.
About WTLS
The WAP Browser configuration is designed to use WTLS to encrypt data that your BlackBerry® device sends and receives over the Internet
through a WAP gateway. Communication between your device and the WAP gateway is encrypted using WTLS. Communication between
the WAP gateway and content servers is encrypted using TLS or SSL.
