Comparison To CRLs
- Since an OCSP response contains less information than a typical CRL (certificate revocation list), OCSP can feasibly provide more timely information regarding the revocation status of a certificate without burdening the network. However, the greater number of requests and connection overhead may overwhelm this benefit if the client does not cache responses.
- Using OCSP, clients do not need to parse CRLs themselves, saving client-side complexity. However, this is balanced by the practical need to maintain a cache. In practice, such considerations are of little consequence, since most applications rely on third-party libraries for all X.509 functions.
- CRLs may be seen as analogous to a credit card company's "bad customer list" – an unnecessary public exposure.
- OCSP discloses to the responder that a particular network host used a particular certificate at a particular time. OCSP does not mandate encryption, so this information also may be intercepted by other parties.
