Universal Messaging supports SSL encryption by providing the nsps and nhps SSL-enabled protocols. These protocols enable clients to connect to a Universal Messaging realm server running a specific protocol on a port using all or specific physical network interfaces.

Defining an SSL-enabled interface ensures that clients can connect to a realm server only after presenting the correct SSL credentials and authenticating with the server.

SSL authentication occurs within the Universal Messaging handshake, which uses the JVM's JSSE provider. This ensures that any unauthorized connections are SSL-authenticated before any Universal Messaging specific operations can be performed.

You create an SSL-enabled interface in the same way as you create a non-SSL interface, but you must configure several SSL-related attributes in addition to the basic attributes.

For information about how to create an SSL interface using the Universal Messaging Enterprise Manager, see Creating an SSL-Enabled Interface.
