Kontroll kan även ske med varianter på OCSP, till exempel så kallad OCSP stapling där till exempel en webbserver svarar över HTTPS och säger att det egna

OCSP stapling is used during the Transport Layer Security (TLS) handshake between the client and the server to check the server certificate revocation status. The server makes the OCSP request to the OCSP responder and staples the OCSP responses to the certificates returned to the client.

OCSP stapling improves the OCSP protocol by letting the webserver instead of the browser query the CA on the status of the SSL certificate. Online certificate status protocol stapling (OCSP stapling; formally TLS Certificate Status Request extension) is an enhancement to the standard OCSP protocol, which benefits end-users such as Web server administrators, application developers and browser developers for checking digital certificates, or public key certificates, statuses as alternative to OCSP. OCSP Stapling Much like the previous status-checking method, OCSP stapling is a process that uses the online certificate status protocol. However, it’s a more advanced way of doing so. Instead of relying on the client to perform certificate revocation status checks, it places that responsibility on the web server instead.

GnuTLS will automatically consider the stapled OCSP response during the TLS certificate verification (see gnutls_certificate_verify_peers2). OCSP stapling presents several advantages including the following: The relying party receives the status of the web servers certificate when it is needed (during the SSL/TLS handshake). No additional HTTP connection needs to be set up with the issuing CA. OCSP stapling provides added security by reducing the number of attack vectors. OCSP Staplingは、OCSP要求をTLSサーバが適切なタイミングで行い、OCSP応答をキャッシュ、TLSハンドシェイク時に、TLSクライアントから要求 (ocsp status request)があれば、Certificate StatusとしてOCSP応答データを応答する。.

When you enable OCSP Stabling, IIS just send a request to the OCSP Server URL and get response body from OCSP server during the SSL handshake. Then IIS send certificate and OCSP status to client side to continue the handshake.

This looks like a problem with OCSP Stapling on the server because it works when OCSP Stapling is disabled Jag har testat OSCP-häftning och arbetar på en Ubuntu 16.04.1-server som kör Nginx 1.11.4 och använder Certbots OCSP Must-Staple TLS-funktionstillägg. Att tillfälligt inaktivera OCSP-häftning på Firefox kan hjälpa. En annan teknisk term associerad med denna process är OCSP Stapling.

OCSP stapling uses the Online Certificate Status Protocol (OCSP) to remove a browser’s need to check with a third party when determining if a security certificate is valid. OCSP stapling essentially “staples” the status verification to the responding webserver, which you control, rather than relying on a third-party server that you do not.

Next, the issuing CA’s server responds with the OCSP status and a timestamp. From this point, whenever a client connects the server staples the OCSP response to the certificate when it’s presented during the handshake. So you have configured OCSP stapling and you want know if it’s actually working, it’s easy enough to check using the openssl s_client command: openssl s_client -connect login.live.com:443 -tls1 -tlsextdebug -status.

First things first.

CSP Stapling moves that second network request from the web browser to the web server. The web server will make a periodic call to the CA, get the OCSP response, and send it back when the web browser starts a HTTPS connection. This may seem strange to have the web server, verify it's own certificate, but the OCSP response is actually signed by the CA and so it's easy for the browser to tell if
