CA Certificates
Learn about Certificate authority (CA) configuration and trust management.
Certificate Authority (CA) certificates are used to validate other certificates. Connectware uses a certificate system that includes both built-in Cybus CA certificates and any custom CA certificates you choose to add. These certificates establish trust relationships between different systems and verify the authenticity of connections.
CA Certificate Types
Default Cybus CA Certificates
Connectware comes with built-in Cybus CA certificates that are pre-installed and managed by the system. These provide the baseline security infrastructure for Connectware operations.
Custom CA Certificates
Custom CA certificates are user-provided Certificate Authority certificates that you add to the system to establish trust for secure communications with external systems. These certificates allow Connectware to authenticate and verify devices, clients, or servers that use certificates signed by a non-default or custom CA, rather than relying solely on the built-in Cybus CA.
By adding custom CA certificates, you can integrate your own Public Key Infrastructure (PKI) to ensure that Connectware can recognize and trust certificates issued by external CAs. This increases security and flexibility for specific industry use cases or corporate policies.
Adding Custom CA Certificates
You can add custom CA certificates to Connectware via the Admin UI and via the certs
volume.
Adding Custom CA Certificates via the Admin UI
You can add your custom CA certificate to Connectware via the Admin UI. When you add a certificate, a backup of the current certificates is created. The last backup will be overwritten with the newly created backup and then the uploaded certificate will be appended to the current certificate chain.
Select User > User Certificates.
In the file browser, select your certificate file and click Open.
