(Go) SFTP Auth Failure Reason (AuthenticatePwPk)This example demonstrates how to determine the failure reason for the case where both a password and private key are required for authentication. If authentication fails, was it because of an invalid private key, or an invalid password? Note: This example requires Chilkat v11.0.0 or greater.
