    CRL mode descriptions:
        DISABLED: No revocation check is done.
        ENABLED: Revocation check is done in the strictest way. The endpoint must expose at least one fully valid
            certificate chain. Any check error invalidate the chain.
        ADVISORY: Revocation check is done in a more relaxed way. Only a revocated certificate can invalidate
            the chain. An error is treated positively (as a successful check).
