Rotate Certificates
Manage the certificates of your edge device by creating new ones and revoking old ones.
A certificate/key pair is used in MQTT mTLS connections to the TilliT IoT Cloud. It's important that the keys for this connection are kept safe and secure. For this reason, all certificate/key pairs can only be downloaded once at the time of creation. If you lose your certificate, or you would like to swap out the certificates for your connection, you can use the Manage Certificates screen to achieve this.
Create a new Certificate
Open an edge, and navigate to the Manage Certificates screen by using the Actions button
On the following screen you will see existing certificates for the edge. To create a new one, click on Create Certificate
After the request to create completes, your browser will automatically download the created certificate. Be sure to save it
You will also see the new certificate in the list. This list is always ordered by oldest first, and the name of the ID of the certificate is also located on the .zip file
Remove the old Certificate
A maximum of two certificates can be associated to an edge. This allows for a new certificate to be created and then swapped out with the old one. Once this has been completed, the old certificate should be removed.
When multiple certificates are listed, a red cross will be visible to choose a certificate to remove. Click the the red cross to remove the appropriate certificate.
A confirmation dialog will appear. Click Delete to confirm the action
Now, the list of certificates shows only one certificate.
