ssl - Using a single certificate for inter-node encryption on Cassandra -


i have inter-node encryption setup on small cassandra cluster (4 nodes), , each node has own key pair. means need distribute trusted keystore nodes contains public key every other node in cluster, makes bit of pain update when add nodes cluster.

does cassandra allow using single certificate/key nodes in cluster, or complain? docs see online tell me generate separate key pair each node, not address sharing certificates. if allowed, drawbacks method?

adding ca cert truststore of each node sufficient.
