There is not possibility to use alternative JSSE Cipher Suite Names for IBM JDK ------------------------------------------------------------------------------- Key: ELY-438 URL: https://issues.jboss.org/browse/ELY-438 Project: WildFly Elytron Issue Type: Bug Components: SSL Reporter: Hynek Švábek Assignee: Darran Lofthouse Priority: Blocker Fix For: 1.1.0.Beta8, 1.0.3.CR1 There is not possibility to use alternative JSSE Cipher Suite Names for IBM JDK8 Interchange TLS prefix to SSL and vice versa is not supported. Here is list of standard JSSE Cipher Suite Names http://docs.oracle.com/javase/8/docs/technotes/guides/security/StandardNa... In my opinion this file is mapping file for our purpose. It is? https://github.com/wildfly-security/wildfly-elytron/blob/master/src/main/... For IBM JDK are different JSSE Cipher Suite Names (different prefix). Most items from this list are missing in MechanismDatabase.properties mentioned above. http://www.ibm.com/support/knowledgecenter/SSYKE2_8.0.0/com.ibm.java.secu... For example: JSSE Cipher Suite Name *SSL_ECDHE_RSA_WITH_AES_128_CBC_SHA* is only defined for IBM JDK. It is *TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA* for Oracle JDK. If I try start server with JSSE Cipher Suite Name *SSL_ECDHE_RSA_WITH_AES_128_CBC_SHA* I will get this error: {code} 16:55:25,594 ERROR [org.jboss.msc.service.fail] (MSC service thread 1-2) MSC000001: Failed to start service jboss.undertow.listener.https: org.jboss.msc.service.StartException in service jboss.undertow.listener.https: Failed to start service at org.jboss.msc.service.ServiceControllerImpl$StartTask.run(ServiceControllerImpl.java:1904) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1153) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:628) at java.lang.Thread.run(Thread.java:785) Caused by: java.lang.IllegalArgumentException: ELY05017: Token "SSL_ECDHE_RSA_WITH_AES_128_CBC_SHA" not allowed at offset 33 of mechanism selection string "SSL_ECDHE_RSA_WITH_AES_128_CBC_SHA" at org.wildfly.security.ssl.CipherSuiteSelector.fromString(CipherSuiteSelector.java:399) at org.wildfly.extension.undertow.HttpsListenerService.startListening(HttpsListenerService.java:125) at org.wildfly.extension.undertow.ListenerService.start(ListenerService.java:138) at org.jboss.msc.service.ServiceControllerImpl$StartTask.startService(ServiceControllerImpl.java:1948) at org.jboss.msc.service.ServiceControllerImpl$StartTask.run(ServiceControllerImpl.java:1881) ... 3 more 16:55:25,598 ERROR [org.jboss.as.controller.management-operation] (Controller Boot Thread) WFLYCTL0013: Operation ("add") failed - address: ([ ("subsystem" => "undertow"), ("server" => "default-server"), ("https-listener" => "https") ]) - failure description: {"WFLYCTL0080: Failed services" => {"jboss.undertow.listener.https" => "org.jboss.msc.service.StartException in service jboss.undertow.listener.https: Failed to start service Caused by: java.lang.IllegalArgumentException: ELY05017: Token \"SSL_ECDHE_RSA_WITH_AES_128_CBC_SHA\" not allowed at offset 33 of mechanism selection string \"SSL_ECDHE_RSA_WITH_AES_128_CBC_SHA\""}} {code}
