OCSP Stapling is a TLS extension that enables the web server to cache Certificate Revocation status information and not placing the onus on the web client to make the request directly with the Certificate Authority (CA) OCSP-Stapling auf Apache aktivieren Apache 2.3 und höher unterstützen OCSP-Stapling. Um die OCSP-Antwort im Voraus zu aktivieren, muss der Webserver einen Zeiger auf den OCSP-Responder enthalten. Dies ist eine Empfehlung des CA/Browser Forums zu den grundlegenden Anforderungen, die alle von Xolphin gelieferten Zertifikate erfüllen OCSP (Online Certificate Status Protocol) ist ein Protokoll zur Überprüfung, ob ein SSL-Zertifikat gesperrt wurde. Es wurde als Alternative zur CRL erstellt, um die SSL-Aushandlungszeit zu verkürzen prego Computer, zeugs Ab Apache Version 2.4 (in Debian Jessie enthalten) wird OCSP Stapling unterstützt. OCSP steht für Online Certificate Status Protocol. Damit kann die Gültigkeit eines Zertifikates abgefragt werden The Online Certificate Status Protocol (OCSP) is a mechanism for determining whether or not a server certificate has been revoked, and OCSP Stapling is a special form of this in which the server, such as httpd and mod_ssl, maintains current OCSP responses for its certificates and sends them to clients which communicate with the server

How to configure OCSP stapling on Apache - Bobcare

The OCSP stapling cache is per-process, and nginx doesn't initiate an OCSP request until it receives the first SSL connection to a site. However, nginx doesn't wait for the OCSP response to complete before servicing the connection, so the first connection never gets a stapled response To understand OCSP stapling, it is necessary to understand OCSP, the Online Certificate Status Protocol. OCSP is a protocol for determining whether a certificate is revoked (for instance, because its private key was compromised). Every time a browser connects to an HTTPS website, it contacts the OCSP responder specified in the SSL certificate, and asks if the certificate is revoked Apache 2.3 and later support a feature called OCSP stapling. When enabled a server pre-fetches the OCSP response for its own certificate and delivers it to the user's browser during the TLS handshake. This approach offers a privacy advantage Check for OCSP stapling support on Apache. OCSP stapling is supported on Apache HTTP Server where version >=2.3.3. We run the following command to check the version of the apache installation. apache2 -v httpd -v. 2. Retrieve the CA bundle. Now, we retrieve the root CA and intermediate CA's certificate in PEM format. Then we save them in a single file. This is for StartSSL's Root and.

Die Antwort wird quasi an den Verbindungsaufbau angetackert, woher der Name OCSP Stapling rührt. Zunächst waren die Implementierungen der Webserver wie Nginx oder Apache für Stapling fehlerbehaftet, doch hat sich diese Situation wesentlich verbessert und es existiert mit mod_md in aktuellen Apache-Versionen eine einfache Möglichkeit OCSP-Stapling für alle ausgelieferten Zertifikate zu. In order to support OCSP Stapling when a particular server certificate is used, the certificate chain for that certificate must be configured. If it was not configured as part of enabling SSL, the AH02217 error will be issued when stapling is enabled, and an OCSP response will not be provided for clients using the certificate This mechanism saves a roundtrip between the client and the OCSP responder, and is called OCSP Stapling. The server will send a cached OCSP response only if the client requests it, by announcing support for the status_request TLS extension in its CLIENT HELLO. Most servers will cache OCSP response for up to 48 hours I would like to enable OCSP stapling in my Apache server. I'm using: Server: Apache/2.4.7 on Ubuntu; Certificate: Let's Encrypt; To the file: /etc/apache2/sites-available/default-ssl.conf I added: SSLUseStapling on Then, I edited: /etc/apache2/mods-available/ssl.conf adding this line: SSLStaplingCache shmcb:/tmp/stapling_cache(128000

Previously we talked about OCSP, OCSP Stapling and OCSP Stapling on Nginx.Now, we will configure OCSP Stapling In Apache 2.4 It is important to avoid some settings of OCSP Stapling on a production website as it can give errors like OCSP Response Expired or just in case of Nginx 502. Here is how to configure OCSP Stapling on Apache 2.4+ with full configuration
  2. Click on the OCSP Stapling button: For Plesk Onyx 17.5 and below. Note: The certificate installed on the domain must contain both root certificate and all the intermediate certificates. In case nginx is used: Log into Plesk. Navigate to Plesk > Domains > example.com > Apache & nginx Settings and add the following configuration to the Additional nginx directives field: CONFIG_TEXT: ssl_stapling.
  3. This posts explains howto enable OCSP stapling on Apache2 webserver. By adding the signed revocation status of your certificate in the TLS handshake, the browser immediately knows if you certificate is revoked or not. Without this info, the browser would have to make an OCSP request to an OCSP responder to obtain this info. OCSP stapling is defined in chapter 3.6 of RFC 4366. Implementing OCSP.
  4. OCSP stapling relieves the client of querying the OCSP responder on its own, but it should be noted that with the RFC 6066 specification, the server's CertificateStatus reply may only include an OCSP response for a single cert. For server certificates with intermediate CA certificates in their chain (the typical case nowadays), stapling in its current implementation therefore only partially.
  5. imal. Certs are all LetsEncrypt generated from within ISPConfig and all check out as valid. What i have found is editing the Apache config and disabling OCSP stapling removes this delay completely but obviously this is a bit of a hack

I'm very much a security novice and I don't manage my server myself (we have a fab hosting company who does most of the work), however I want to understand this a bit better. I am wanting to enhance the encryption on the websites on our server. I. Also, one tricky thing that @SwartzCr noticed: I believe OCSP Stapling in Apache depends on the socache_shmcb module, which was introduced in 2.4. In order to be backwards compatible with 2.2 you'll have to check the version you're working with. It's possible that OCSP Stapling works in 2.2 if you simple omit the shmcb parts. You may also be able to fudge it for a first pass by only enabling. Overview Advantages Disadvantages OCSP stapling setup and test Overview Most applications that depend on X.509 certificates need to validate the status of the certificates used when performing authentication, signing, or encryption operations. This certificate validity and revocation check are performed for all certificates in a certificate chain, up to the root one

Ora posso riavviare Apache senza problemi, tuttavia, OCSP non sembra funzionare, in base a: openssl s_client -connect www.example.com:443 -servername www.example.com -status < /dev/null OCSP response: no response sen Update ZLB information for OCSP Stapling and ciphersuite 2.4 Julien Vehent Moved a couple of aes128 above aes256 in the ciphersuite 2.3 Julien Vehent Precisions on IE 7/8 AES support (thanks to Dobin Rutishauser) 2.2 Julien Vehent Added IANA/OpenSSL/GnuTLS correspondence table and conversion tool 2.1 Julien Vehent RC4 vs 3DES discussion. r=joes r=tinfoil 2.0 Julien Vehent, kang Public release.

For backward compatibility reasons, switching strategies must be an opt-in by the user. I will. I confirmed that various web browsers (Edge, Chrome and Firefox) triggered Apache to make calls to the OCSP responder when they hit the Apache page.
