Since an OCSP response has less data to parse, the client-side libraries that handle it can be less complex than those that handle CRLs. [11] OCSP discloses to the responder that a particular network host used a particular certificate at a particular time. OCSP does not mandate encryption, so other parties may intercept this information. [2]
A CRL is generated and published periodically, often at a defined interval. A CRL can also be published immediately after a certificate has been revoked. A CRL is issued by a CRL issuer, which is typically the CA which also issued the corresponding certificates, but could alternatively be some other trusted authority.
OCSP stapling can solve the operational challenges of OCSP, namely additional network requests causing latency and privacy degradation. [33] However, it can be susceptible to downgrade attacks by an on-path attacker. [9] RFC 7633 defines an extension that embeds a requirement into a certificate to be stapled to a valid OCSP response. [34]
X.509 and RFC 5280 also include standards for certificate revocation list (CRL) implementations. Another IETF-approved way of checking a certificate's validity is the Online Certificate Status Protocol (OCSP). Firefox 3.0 enabled OCSP checking by default, as did versions of Windows from at least Vista and later. [9]

It must be continuously updated with current CRL information from a certificate authority which issued the certificates contained within the CRL. While this is a potentially labor-intensive process, the use of a dedicated validation authority allows for dynamic validation of certificates issued by an offline root certificate authority .
