Dear Wiki user, You have subscribed to a wiki page or wiki category on "Cassandra Wiki" for change notification.
The "InternodeEncryption" page has been changed by DavidAllsopp: http://wiki.apache.org/cassandra/InternodeEncryption New page: Inter-node encryption uses standard TLS/SSL to authenticate and encrypt messages between nodes, to preotect data in transit between nodes, and to prevent unauthorized access to/control of nodes. Encryption can be applied to all inter-node messages, or just messages crossing from one Datacenter to another. This page needs fleshing out... skeleton instructions from https://issues.apache.org/jira/browse/CASSANDRA-3051 are: 1. follow the steps for generating a keystore and a trust store here: http://download.oracle.com/javase/6/docs/technotes/guides/security/jsse/JSSERefGuide.html#CreateKeystore 2. plug those files into encryption_options in cassandra.yaml 3. make sure encryption_options.internode_encryption = all in the yaml. ---- See also SimpleAuthenticator for details of the authentication of Thrift clients (rather than between nodes).
