Universal Messaging fully supports SSL and offers support for SSL enabled TCP/IP sockets as well as HTTPS. When SSL is used the subject used for entitlements can be extracted from the clients certificate CN attribute.
Universal Messaging's SSL implementation supports both client side and anonymous (Server side) SSL. Different SSL certificate chains can be assigned to different Universal Messaging interfaces, each one supporting its own set of cryptographic algorithms. There is no limit to the number of interfaces and therefore different SSL certificate chains that can be supported on a single Universal Messaging Realm server.
For more information on configuring Universal Messaging interfaces to use SSL encryption with Universal Messaging please see the Enterprise Manager guide.
