Marcus Eriksson created CASSANDRA-5290:
------------------------------------------
Summary: Refactor SSL support to make it possible enable without
total cluster downtime
Key: CASSANDRA-5290
URL: https://issues.apache.org/jira/browse/CASSANDRA-5290
Project: Cassandra
Issue Type: Improvement
Reporter: Marcus Eriksson
Priority: Minor
should be possible by doing something similar to what compression does today:
* node A connects to node B, indicating that it wants SSL
* node A and B upgrade/wrap sockets
* node B must still be able to talk to A (and all other nodes) without SSL
nothing secret is shared during hand shake phase
one difference compared to compression is that after the cluster is rolled
there must be a way to not allow any non-ssl talk at all to avoid any
plaintext-communication due to configuration mistakes. this should be doable
via configuration and perhaps JMX
