What is 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.

Specifically, the RFC calls out this functionality: Allow TLS clients and servers to negotiate that the server sends the client certificate status information (e.g., an Online Certificate Status Protocol (OCSP) [RFC2560] response) during a TLS handshake. I would like to enable OCSP stapling in my nginx server. I'm using nginx version: nginx/1.6.2 debian Let's Encrypt certificate I'm really unexperienced in this matter, so it might be a trivial is 2019-07-11 2013-05-07 OCSP Stapling is one of the many new features introduced with httpd 2.4. It allows client software using SSL to communicate with your server to efficiently check that your server certificate has not been revoked. The primary how-to for OCSP Stapling in httpd is at OCSP Stapling How-To. OCSP Expect-Staple is a new reporting mechanism to allow site owners to monitor how reliable their OCSP Stapling implementation is.

Instead of relying on the client to perform certificate revocation status checks, it places that responsibility on the web server instead. 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. How OCSP Stapling Works First, the webserver hosting the SSL certificate sends a query to the issuing CA’s server.

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

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。. TLSクライアントが、ocsp status requestを要求するかどうかは、サーバ証明書の拡張領域に認証局情報アクセスが登録されているかどうかよる。.

Thank you 2020-03-15 · OCSP stapling is an alternative approach to the original Online Certificate Status Protocol (OCSP) for determining whether an SSL certificate is valid or not. It does this by allowing the web server to query the OCSP responder (a certificate authority's server that listens for OCSP requests) and then caches the response . When OCSP stapling is used, this message is sent to the server with the status_request extension that indicates that the server should perform an OCSP request. After processing the ClientHello message, the server sends an OCSP request to the appropriate OCSP responder for each certificate. OCSP stapling configuration. Configuring OCSP stapling involves enabling the feature and configuring OCSP.

Also defined is a new method based on the Online Certificate Status Protocol (OCSP) that servers can use to provide status information about not only the server's own certificate but also the status of intermediate certificates in the chain.
