There's a JIRA issue that's been open for three years for kafka to support openssl with JNI: https://issues.apache.org/jira/browse/KAFKA-2561 https://issues.apache.org/jira/browse/KAFKA-2561 Not sure it's going to get done at this point. I've only recently started using kafka and found the TLS issues to be somewhat surprising. AES-NI has been around for how long now? I speculate that this is because it's come out of the hadoop community and they haven't really had much luck implementing security features.
