show ssl ocsp-response

Description

The Online Certificate Status Protocol (OCSP) allows a client (browser) to see the revocation status of an SSL/TLS certificate in real time. A client contacts an OCSP Responder server to get the OCSP response, which contains the certificate's revocation status. The Responder server is often managed by the certificate issuer. OCSP stapling is a mechanism that allows you to fetch the revocation status ahead of time and attach it to the certificate, saving the client from needing to make that request to the OCSP Responder server.

The OCSP response contains a revocation status for the certificate of either good, revoked, or unknown.

Use the show ssl ocsp-response command to display the IDs of the OCSP tree entries corresponding to all the OCSP responses used in HAProxy, as well as the issuer's name and key hash and the serial number of the certificate for which the OCSP response was built.

To display the contents of a specific OCSP response, provide the response ID as an argument. The information displayed is the same as in an openssl ocsp -respin ocsp-response -text call.

To set the OCSP response, use the Runtime API command set ssl ocsp-response.

You can also display the OCSP response using show ssl cert.
