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.

Cluster.Builder()

//.AddContactPoints("")

//.WithPort(9042)

.WithCloudSecureConnectionBundle(@"filename.zip")

.WithLoadBalancingPolicy(new DCAwareRoundRobinPolicy(""))

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

.Build();

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()
    .AddContactPoints(...)
    .WithSSL()
    .Build();

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!

yes already gone through this & tried couple of SSL opts

note-we have ca-cert.der, ca-cert.pem and truststore.jks

var cluster Cluster.Builder

AddContactPoints

WithPort 9042

WithLoadBalancingPolicy new DCAwareRoundRobinPolicy

WithAuthProvider new PlainTextAuthProvider superusr pass

WithCredentials user pass

WithSSL new SSLOptions SetCertificateCollection new X509Certificate2Collection


new X509Certificate2("path to .PEM or .DER cert"

WithSSL(new SSLOptions().SetRemoteCertValidationCallback(

(sender, certificate, chain, errors) serverCertificateValidator.Validate(certificate, chain, errors)))

WithSSL(new SSLOptions().SetCertificateRevocationCheck(true))

Build();

Error on - cluster.Connect(kespace name);

All hosts tried for query failed (tried host ip here:9042: AuthenticationException Authentication failed, see inner exception.'; host ip here:9042: IOException 'Unable to read data from the transport connection: An existing connection was forcibly closed by the remote host

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