Generate a CA Certificate using an IP address

If you have a working DNS configured for your device, you can enter the hostname to the DWS Server Address when creating an Application in the DRS configurations. Then the CA Certificate is automatically generated using the hostname.

However, if you do not have a working DNS, an IP address should be entered in the DWS Server Address so the CA Certificate can be generated using this IP. To use the DWS IP address, do the following:

  1. Stop the DWS Service.
  2. Open the Conf folder: C:\Windows\System32\config\systemprofile\AppData\Local\Nuance\Integrated\DWS\webserver\conf.
  3. Delete the current certificate and key store files (if any) in the Conf folder including dws-root-ca.der, dws-server-key.jks and dws-signed-server-key.jks.
  4. Edit the DWSSettings.properties file:

    • Add line dwsGenerateIPAddressSubjectCA=true to the file.

    • Set dwsServerCanonicalHostName=[DWS_IP_address].

  5. Restart the DWS service.
If an IP Address is used to generate the CA Certificate, after the client is uninstalled, the CA Certificate is not deleted on the device.
