(PowerBuilder) SFTP use Cert's Private Key for Authentication (Windows)Demonstrates how to use the private key of a pre-installed certificate (on Windows) for SFTP authentication. The certificate's private key must be marked as "exportable" when originally installed. Note: This example requires Chilkat v11.0.0 or greater.
