Installing a signed SSL certificate on a PC-based BACnet Capture Tool

By default, the Optigo BACnet Capture Tool will install a self-signed certificate, which is generally secure enough for most installations. However, for systems that require a very high level of security, it is possible to update the SSL certificate of the system to a new signed certificate generated by the customer.

Preparation

Before starting the procedure, you will need to acquire a certificate that has been signed by a Certificate Authority (CA). We do not have any specific recommendations for this, but Wikipedia has a reasonably complete list of CAs. 

You will need to obtain the .crt and .key file from the signed certificate and rename them to optigo.crt and optigo.key.

Installation

1. Copy the optigo.crt and optigo.key into the capture tool's 'certs' folder.
   NOTE: You must have full administrator privileges.
   
   Windows (default)
   C:\Program Files (x86)\Optigo Capture Tool\data\certs
   
   Linux (default)
   /opt/OptigoCaptureTool/data/certs/
   
    
2. Restart the OptigoCaptureTool service.
   
   Windows
   Via the 'Services' application
   
   Linux
   Via the terminal (service OptigoCaptureTool restart)
   
   
    
3. Navigate to the captureTool (https://localhost:4000/login) and, through the browser, verify that the SSL certificate has been updated.

Troubleshooting

1. Make sure that you have provided the correct .crt and .key files (i.e. they are part of a matched pair and have not expired).
   
   
    
2. Confirm that the files have been copied to the correct location.
   
   
    
3. Look in the logs to determine if there was an error updating the SSL certificate.
   
   Windows (default)
   C:\Program Files (x86)\Optigo Capture Tool\data\log\node.exe-yyyy-mm-dd.log
   
   Linux (default)
   /opt/optigoCaptureTool/data/log/node.exe-yyyy-mm-dd.log
