Examples in this documentation depend on features activated in the ds-evaluation setup profile. For details, refer to Learn about the evaluation setup profile.

The code samples demonstrate how to contact the server over HTTPS using the deployment CA certificate. Before trying the samples, generate the CA certificate in PEM format from the server deployment ID and password:

$ dskeymgr \
 export-ca-cert \
 --deploymentId $DEPLOYMENT_ID \
 --deploymentIdPassword password \
 --outputFile ca-cert.pem
