    Setting Up and Managing iChat Service 
 
The digital certificate can be a self-signed certificate or a certificate imported from a 
certificate authority. For information about defining, obtaining, and installing 
certificates on your server, see Server Administration.
iChat uses SSL to encrypt your chat messages that are sent over the network. However, 
if your iChat server is logging chat messages, the messages are stored on the server in 
an unencrypted format. These unencrypted chat messages can be easily viewed by 
your server administrator. For information about message logging, see “Configuring 
Logging Settings”  on page 21
.
To identify an SSL certificate for use by iChat:
1
Open Server Admin and connect to the server.
2
Click the triangle to the left of the server.
The list of services appears.
3
Click iChat, then click Settings.

From the SSL Certificate pop-up menu, choose the certificate you want iChat to use.
The menu lists all SSL certificates that are installed on the server. To create or add 
certificates, choose Manage Certificates from the SSL Certificate pop-up menu.
For more information about creating and managing server certificates, see Server 
Administration
