Certificate
class Certificate(val platform: Platform, message: String? = null, cause: Throwable? = null) : AttestationException
Indicates a problem verifying the certificate chain the attestation statement is built upon. This can either be just a borked certificate chain (i.e. just a wrong certificate somewhere in the chain), or the chain not being rooted in a valid trust anchor. Most probably, however, a legitimate app on a trusted OS will simply have fallen victim to the system clock being too far ahead. This heavily depends on the OS a device was originally shipped with, (or just Samsung being Samsung and being unable to correctly encode a timestamp conforming to ASN.1)
