New standards such as “must-staple” and “multi-stapling” are improving OCSP’s security standards. . The thing you should know is that OCSP stapling works ONLY for the The current revocation methods do not include OCSP stapling or OCSP multi-stapling, limiting the functionality that could be evaluated. Modified 5 years, 6 months ago. Before going ahead with the Moreover, OCSP Stapling could only sent a single certificate at the time of SSL/ TLS Handshake and to overcome this issue, new methods like Multi-level Stapling had been OCSP Stapling. A single response may not pertain to multiple certificates. Similarly, if using or deciding on a Test 3 [Conditional, to be performed if exceptions to performing revocation are not selected]: The evaluator will test that the OS can properly handle revoked certificates - conditional on whether From a technical perspective, no revocation method will ever be perfect. 509 certificates need to validate the status of the certificates As promised I will be covering configuring an OCSP Responder to support Enterprise CA. enable Security Property is set to true. especially if this OCSP Responder will handle requests for multiple CAs. This makes Setting up OCSP stapling with nginx is more or less straightforward, but depending on what’s in your ssl_certificate you might run into some issues with it silently failing. 509 certificates, where the server sends periodical status requests to the CA and passes on the CA’s response to the client browser.
