How to provide your own device certificate
At Scaleway, a certificate is automatically created and attached to a device upon creation, if you have not previously set up your own Certificate Authority. You also have the option of setting up a specific certificate for your device.
You may need certain IAM permissions to carry out some actions described on this page. This means:
If you choose to replace the certificate, the previous one will be deleted and cannot be recovered. If you want to use a different Scaleway-managed certificate you can delete the device and create a new one using the same device name.
For a custom device certificate to be valid, it must be unique across all your Hubs.
When using a custom device certificate, the device must present the certificate as provided during the certificate replacement.
Switching to a custom device certificate allows for greater flexibility through:
- different key sizes & algorithms.
- different timeframe validity.
- your own personal private key not to be shared on the Internet.
