OCSP is useful for clients who possess limited processing power and memory and even for CAs who have large CRLs (Certificate Revocation Lists). web server) to query the OCSP responder directly and then cache the response. Using IIS? Check out IIS Crypto. However, nginx doesn't wait for the OCSP response to complete before servicing the connection, so the first connection never gets a stapled response. Support for keeping a long-lived (disk) cache of OCSP responses. OCSP-stapling enhances the basic OCSP method by allowing the presenter of a certificate, such as the website hosting the SSL certificate, to deliver the OCSP response to the browser instead of it being delivered by the issuing CA. How To Configure OCSP Stapling on Apache and Nginx Introduction OCSP stapling is a TLS/SSL extension which aims to improve the performance of SSL negotiation while maintaining visitor privacy. You specify protocols and ciphers for your site and understand how to configure them to prevent downgrades to insecure ciphers.

OCSP Stapling improves performance by providing a digitally signed and timestamped version of the OCSP response directly on the web server that the client is connecting to. OCSP Stapling是TLS / SSL扩展其目的是提高SSL协商的性能,同时保持访问者的隐私。与之前的配置,在证书吊销如何工作的一个简短简短走在前面。. > > I am using nginx on several web servers fronted with LVS NAT.

"The team at NGINX is delighted that GlobalSign, DigiCert, and Comodo support the OCSP stapling enhancement to the NGINX webserver," said Igor Sysoev CTO and principal architect at NGINX, "We have been continuously working on enhancements to NGINX that increase performance, reliability and security. -- OCSP --Also OCSP is supported in the current version. Skip to content. However, OCSP stapling supports only one OCSP response at a time, which is insufficient for certificate chains with intermediate CA certs.
