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. [10] 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]
OCSP stapling is designed to reduce the cost of an OCSP validation, both for the client and the OCSP responder, especially for large sites serving many simultaneous users. However, OCSP stapling supports only one OCSP response at a time, which is insufficient for certificate chains with intermediate CA certs. [26] [27]
The Online Certificate Status Protocol (OCSP) allows clients to interactively ask a server (an OCSP responder) about a certificate's status, receiving a response that is cryptographically authenticated by the issuing CA. [29] It was designed to address issues with CRLs. [30] A typical OCSP response is less than 1 kB. [31]
Browsers and other relying parties might use CRLs, or might use alternate certificate revocation technologies (such as OCSP) [4] [5] or CRLSets (a dataset derived from CRLs [6]) to check certificate revocation status. Note that OCSP is falling out of favor due to privacy and performance concerns [7] [8] [9]. Subscribers and other parties can ...
For example, Firefox provides a CSV and/or HTML file containing a list of Included CAs. [8] 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).
The FDA has banned red dye No. 3, as the synthetic additive is known to cause cancer. Nutritionists Ilana Muhlstein and Robin DeCicco discuss what this means for American health.
The Simple Certificate Enrollment Protocol still is the most popular and widely available certificate enrollment protocol, being used by numerous manufacturers of network equipment and software who are developing simplified means of handling certificates for large-scale implementation to everyday users.
