How do I connect to a SSL-enabled cluster using C# driver?

How to connect to SSL enabled Cassandra cluster using c# driver ?

I am using Cassandra hosted by different vendor and that is enabled with SSL

Tried below configuration but getting different errors

Note - In the zip bundle we have "cluster-ca-certificate.der" and "cluster-ca-certificate.pem" and "truststore.jks" only.

Kindly provide way to connect using above certificates.





.WithLoadBalancingPolicy(new DCAwareRoundRobinPolicy(""))

.WithAuthProvider(new PlainTextAuthProvider("user", "password"))

The Builder.WithCloudSecureConnectionBundle() method only works with Astra.

In your application, you need to use the Builder.WithSSL() method to configure the SSL options:

var cluster = Cluster.Builder()

In your previous questions, I've referred you to consult the C# driver documentation to familiarise yourself with how to develop apps. See the TLS/SSL section of the C# driver docs for more information.

There are also SSL code examples on the C# driver repository on GitHub you can use as reference. Cheers!

If you're having issues, please contact your vendor to find out how to connect to their databases. Cheers!
