ClearBlade IoT Core can verify device public key certificates against self-signed CA certificates and CA certificates generated by a trusted third party. Both CA certificates are used the same way but are generated differently.
Self-signed CA certificates | Third-party CA certificates |
|---|---|
Device private key owners can generate the certificates. | A trusted third party must generate the certificates. |
Device private key owners create and own the CA private keys that sign the certificates. | A third party creates and owns the CA private keys that sign the certificates. |
The certificates are free to generate. | Third parties bill to generate certificates and establish CA chain of trust. |

Public keys are specified in the Device resource’s credentials field of the Device resource in the ClearBlade IoT Core API. See DeviceCredential in the Device resource for more information.
