Managing Certificates

The PowerMedia WMS Web User Interface can operate with HTTP or HTTPS. If HTTPS is being used, a padlock appears at the bottom right in the browser display. If HTTP is being used, a padlock does not appear.

To use HTTPS, the PowerMedia WMS must have a server certificate and key, and the browser must have the matching client certificate.

A user-generated security certificate and key can be installed on the PowerMedia WMS. The Web UI uses this certificate/key for HTTPS authentication.

To retrieve a certificate/key, select System>Manage Certificates to display the Manage Certificates page. This page provides the following options:

• CREATE: Creates a self signed certificate and automatically installs it. 

• INSTALL: Imports a certificate and key from a remote server and installs it on the PowerMedia WMS.

• REMOVE: Removes the current certificate from the PowerMedia WMS.

• RESTORE: Restores the previous certificate to the PowerMedia WMS.

Creating a Certificate

When you click CREATE, a certificate is created and automatically installed. The Create Certificate page appears.

Installing a Certificate

When you click INSTALL, a certificate and key can be retrieved from a remote server using Secure access over HTTPS or HTTP. Enter the parameters for the Secure access over HTTPS or HTTP server that holds the certificates and keys. The PowerMedia WMS attempts to access the server, and then displays the available certificates (.crt files) for retrieval. Only certificate files (<filename>.crt) are shown, but there must also be a matching valid key (<filename>.key) present for the certificate in order for the certificate to be displayed in the Web UI. The certificate and the key must have the same name with the appropriate file extension (xx.crt and xx.key). You can navigate through the directory structure, but the window only displays directories and certificates.

To install a certificate:

1. On the Manage Certificates page, click INSTALL to display the Install Certificates page:

2. Browse to the certificate file and click Upload Files to install the certificate and display the results of the installation.

• If the installation is successful, the previous certificate (if there is one) is saved and the Web UI begins using the new certificate as soon as you click Continue.
•  If the installation is not successful an error appears and the update of the certificate does not take place. The certificate is not kept for installation in the future.

Removing a Certificate

To remove the current certificate:

1. On the Manage Certificates page, click REMOVE to remove the current certificate and key from the system and save them.

The Remove Certificate page is displayed to confirm the removal.

The Web User Interface uses HTTP when the CONTINUE button is clicked. The padlock icon at the bottom of the browser display disappears when the screen is next refreshed.

Restoring a Certificate

On the Manage Certificates page, click the RESTORE button to put the previous certificate (if there is one that has been removed or overwritten) back on the system. The Web User Interface uses HTTPS when the CONTINUE button is clicked. The padlock icon at the bottom of the browser display appears when the screen is refreshed.
