verified because of a network error or any other problems, the certificate is
determined as valid.
Selecting High verifies the validity of certificates, and determines only
certificates that have not been revoked as valid.
Certificate Revocation
Check
Select the method to verify the validity of certificates. Select By Retrieving
CRL if the machine retrieves a CRL (Certificate Revocation List) from the
validation authority to verify the revocation status of the certificate. Select By
OCSP if the machine uses OSCP (Online Certificate Status Protocol), which
can verify the validity revocation status of the certificate, to have the
certificate authority or validation authority check the revocation status.
