I've multiple producers to push messages into my kafka broker. Want to secure my topic, so that producers need password to push messages in topic or any kind of protection.

In spring boot got to see below properties.

spring.cloud.stream.kafka.binder.configuration.[security.protocol]=SSL
#spring.cloud.stream.kafka.binder.configuration.[ssl.truststore.location]=D:\\streaming\\MessagingQueingTier\\SSL\\kafka.client.truststore.jks
#spring.cloud.stream.kafka.binder.configuration.[ssl.truststore.password]=clientpass
#spring.cloud.stream.kafka.binder.configuration.[ssl.keystore.location]=D:\\streaming\\MessagingQueingTier\\SSL\\kafka.client.keystore.jks
#spring.cloud.stream.kafka.binder.configuration.[ssl.keystore.password]=clientpass
#spring.cloud.stream.kafka.binder.configuration.[ssl.key.password]=clientpass

Are these properties useful to fulfill my requirment ? And How can I set these properties ? Not able to understand. Can anyone help or share any reference doc to do it ?

Thanks
