Certificate Revocation Settings Configure the settings for certificate revocation retrieval. Level of Certificate Verification Certificate Revocation Check Select a level of certificate verification from Low, Medium, or High. Selecting Low does not verify the validity of certificates.

Selecting High verifies the validity of certificates, and determines only certificates that have not been revoked as valid. 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. 116 | Dell Printer Configuration Web Tool
