public List<VerifiedSCT> getValidSCTs() {
        return Collections.unmodifiableList(validSCTs);
    }
Container for verified SignedCertificateTimestamp.

getValidSCTs returns SCTs which were found to match a known log and for
which the signature has been verified. There is no guarantee on the state of
the log (e.g., getLogInfo.getState() may return STATE_UNKNOWN). Further
verification on the compliance with the policy is performed in PolicyImpl.
