Instant Messenger automatically supports TLS. If you have configured the server to use TLS as described in Activating TLS on the Instant Messaging Server then the server will communicate to the client that it can support a TLS session when Instant Messenger connects to the server. Instant Messenger can then request that the connection be changed to use TLS.
You invoke the legacy SSL version of Instant Messenger by accessing imssl.html or imssl.jnlp from your web browser. These files are located under the resource directory, the base directory under which all the Instant Messenger resources are stored.
The links to these applet descriptor files can also be added to index.html.
Once you have configured legacy SSL for the multiplexor or TLS for the server, you can verify that the Instant Messenger client has made a secure connection.
Log in to Instant Messenger.
If you are using legacy SSL, access imssl.html or imssl.jnlp from your web browser. If you are using TLS, access the client normally. See Invoking Instant Messenger for information.
Instant Messenger will always use TLS if it is available and if the multiplexor is not set up for legacy SSL.
On the Instant Messenger Main Window, ensure the lock icon is visible.
The lock icon appears on the bottom right corner of the Main Window when Instant Messenger is using a secured transport, either SSL or TLS.
