Use case:
VIP AuthHub SDK is used for IOS/Android app and is involving trusted devices.
In this case, the device footprint will be encrypted using the public key coming from a hardcoded certificate.
Certificate will eventually expire, would it cause outage?
VIP AH ~ 2.3.1
As of now client SDK does not validate the certificate expiry hence it is pure PKI where client SDK just extract the public key from the hardcoded cert and encrypt the part of the device signature.
So for now, there is no expiry involved in the validation of device signature in trusted device flow.
