Certificates

The following certificates are used when devices and applications need to verify IoTDA.

  • The certificates apply only to Huawei Cloud IoTDA and must be used together with the corresponding domain name.
  • CA certificates can no longer be used to verify server certificates upon expiration. Replace CA certificates before they expire to ensure that devices can connect to the IoT platform properly.
