Configure multiple certificates for the Replication Engine

The Replication Engine for Kafka currently uses a single keystore for the certificates used to encrypt both the connection to its source datastore and the connection to the targeted Schema Registry.

Although it is possible to configure multiple certificates within the keystore, only the certificate with the alphabetically first alias is chosen for encryption.

However, our security guidelines require us to use a certificate of the network hostname for encrypting the connection between Replication Engine and source datastore and a certificate of the user for writing to the Schema Registry. Both hostname and user name cannot be the same, requiring us to use two different certificates. This cannot currently be configured and prevents us from running CDC in our production environment.

A possible solution would be to either allow configuring two different keystores or to configure the alias names of any certificates to use for either connection.

    IBM Update:

    Thanks for filing this requirement.

    We think this requirement is valid, but the work is not committed at this time.

    Looking further into this issue, the keystore should be configurable by creating a KCOP and setting the variables






    to the configuration map passed to the KafkaAvroSerializer. These parameters are (at least in the Confluent implementation which I understand CDC to use) eventually passed to SslFactory to create parameters for an SSL connection. I do not understand why setting these parameters does seem to have any effect at all.
