Description

Hello,

The current internode encryption between cassandra nodes uses a keystore and truststore. However there are some use-case where users are okay to allow any one to trust as long as they have a keystore. This is requirement is only for encryption but not trusting the identity.

It would be good to have an option to disable the Truststore CA check for the internode_encryption.

 

In the current cassandra.yaml, there is no way to comment/disable the truststore and truststore password and allow anyone to connect with a certificate. 

 

though the require_client_auth: is set to false, cassandra fails to startup if we disable truststore and truststore_password as it look for default truststore under `conf/.truststore`

 

server_encryption_options:
 internode_encryption: all
 keystore: /etc/cassandra/keystore.jks
 keystore_password: mykeypass
 truststore: /etc/cassandra/truststore.jks
 truststore_password: truststorepass
 # More advanced defaults below:
 # protocol: TLS
 # algorithm: SunX509
 # store_type: JKS
 # cipher_suites: [TLS_RSA_WITH_AES_128_CBC_SHA,TLS_RSA_WITH_AES_256_CBC_SHA,TLS_DHE_RSA_WITH_AES_128_CBC_SHA,TLS_DHE_RSA_WITH_AES_256_CBC_SHA,TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA,TLS_ECDHE_RSA_WITH_AES_256_CBC_SHA]
 # require_client_auth: false
 # require_endpoint_verification: false
