> Key: CASSANDRA-9590
> URL: https://issues.apache.org/jira/browse/CASSANDRA-9590
> Project: Cassandra
> Issue Type: Improvement
> Components: Core
> Reporter: Stefan Podkowinski
> Assignee: Stefan Podkowinski
> Fix For: 2.1.x
>
>
> Enabling encryption for native transport currently turns SSL exclusively on
> or off for the opened socket. Migrating from plain to encrypted requires to
> migrate all native clients as well and redeploy all of them at the same time
> after starting the SSL enabled Cassandra nodes.
> This patch would allow to start Cassandra with both an unencrypted and ssl
> enabled native port. Clients can connect to either, based whether they
> support ssl or not.
> This has been implemented by introducing a new {{native_transport_port_ssl}}
> config option.
> There would be three scenarios:
> * client encryption disabled, {{native_transport_port}} unencrypted,
> {{native_transport_port_ssl}} not used
> * client encryption enabled, {{native_transport_port_ssl}} not set,
> {{native_transport_port}} encrypted
> * client encryption enabled, {{native_transport_port_ssl}} set,
> {{native_transport_port}} unencrypted, {{native_transport_port_ssl}} encrypted
> This approach would keep configuration behavior fully backwards compatible.
