Certificate Management

Used to centrally manage certificates. Each type of certificate is stored independently. Includes:

  • Web Server Certificate: Used to configure secure communication between Web clients (such as browsers) and the VC Hub server.
  • Redundancy / Networking Certificate: Used to configure secure communication between multiple VC Hub nodes in redundancy or networking mode.
  • MQTT Broker Certificate: Used to configure secure communication between MQTT clients (such as field devices or VC Hub clients) and the MQTT Broker.
