CA Service
The CA Service is the certificate authority behind every device identity. Given a certificate signing request, it validates the requester, signs a short-lived X.509 certificate, and records it for later revocation.
Why short-lived certs
A device certificate is valid for 90d. Short lifetimes mean a lost or cloned key stops working soon on its own — rotation, not revocation, is the primary defence.
