Resolution:
TIBCO Adapter for Siebel Supports SSL when the JMS transport type is chosen by the runtime adapter. The transport can be configured to use trusted store and identity resource for use in SSL (Secure Socket Layer) configurations.

TIBCO uses OpenSSL, implementing the Secure Sockets Layer (SSL v2/v3) and Transport Layer Security (TLS v1). Please refrain from using Version 2 as it is not recommended by TIBCO.

The encryption is set at the EMS Server level by using the parameter “ssl_server_ciphers” in the tibemsd.conf file which may be depending upon the Certificate.
