configure SSL between Application and Tibco EMS broker

To configure SSL/TLS between an application and a TIBCO EMS broker. I’ll outline the steps in a structured way (broker-side, client-side, and validation).

1. Prepare Certificates and Keystores

• Generate a server certificate for the EMS broker (signed by a trusted CA or internal CA).
• Create a keystore (for private key + cert) and a truststore (for CA certificates).
  • Use keytool (Java), openssl, or any PKI tool.
• Example (self-signed for testing): keytool -genkey -alias emsServer -keyalg RSA -keystore ems_keystore.jks -keysize 2048 keytool -export -alias emsServer -keystore ems_keystore.jks -file emsServer.cer keytool -import -alias emsCA -file emsServer.cer -keystore ems_truststore.jks

2. Configure EMS Broker for SSL

1. Edit the EMS configuration (tibemsd.conf): # Enable SSL listening port ssl_port = 7243 # Point to SSL identity (keystore) ssl_server_identity = /path/to/ems_keystore.jks ssl_server_identity_pass = yourKeystorePassword # Trust store (clients) ssl_trusted = /path/to/ems_truststore.jks
2. Restart the EMS broker: tibemsd -config /path/to/tibemsd.conf

3. Configure Application (Java Example)

If your application uses JMS with Tibco EMS:

• Add SSL parameters to the connection factory URL. String url = "ssl://ems-host:7243"; TibjmsConnectionFactory factory = new TibjmsConnectionFactory(url); factory.setSSLStoreType("JKS"); factory.setSSLTrustStore("/path/to/ems_truststore.jks"); factory.setSSLTrustStorePassword("truststorePassword"); factory.setSSLIdentity("/path/to/ems_client_keystore.jks"); factory.setSSLPassword("clientKeystorePassword"); Connection connection = factory.createConnection("user", "password");
• If mutual authentication is required, configure both identity (client cert) and truststore.
• If only server authentication is required, configure just the truststore.

4. Validate Connection

• Test with tibjmsSSLGlobal or tibjmsSSLConsumer/Producer samples that come with EMS.
  Example: tibjmsSSLConsumer -server ssl://ems-host:7243 -topic test.topic
• Check EMS logs (ems.log) for SSL handshake success or errors.
• Verify the certificate chain is trusted by both sides.
