nginx-1.4.0 stable release, which contains all the improvements in 1.3, many of which are new features, including reverse proxies that support WebSocket connections, OCSP stapling, SPDY modules, Gunzip filter, and so on. Nginx 1.4.0 fixes two bugs on a 1.3.16 basis: *) Bugfix:nginx could not being built with the ngx_http_perl_module if the --WITH-OPENSSL option was used; The bug had appeared in 1.3.16. *
In recent years, Google, Baidu, Facebook and other internet giants vigorously implement HTTPS, many large internet companies at home and abroad have also enabled full-site https. Google also launched a new encryption suite chacha20-poly1305 for mobile optimization.Pat Cloud CDN has fully supported Google's launch of the mobile-optimized encryption Suite--chacha20-poly1305. On the cloud platform, all CDN users can enjoy the advantages of this algorithm plus decryption performance, Web page load t

OpenCA:OpenCA is an open source project for building a private PKI. The author Caishuxueqian, has not studied this, hoped that has the relatively clear reader to inform how to apply to the Remote Desktop server authentication. ^-^Difficulties: The client needs to check the certificate revocation status when connecting to the server Remote Desktop. There are two ways to check certificate revocation status: CRL and OSCP1.1 OCSPBy default, the certificate path validation settings use
The main file types and protocols for certificates are: PEM, DER, PFX, JKS, KDB, CER, Key, CSR, CRT, CRL, OCSP, SCEP, etc. Pem–openssl uses the PEM (privacy enhanced Mail) format to hold various information, which is the default way of storing information in OpenSSL. The PEM file in Openssl generally contains the following information: Content type: Indicates what information is stored in this file, which is in the form of "——-BEGIN xxxx--" and corres

The online revocation service is a new component introduced in Windows Server 2008. Is the Microsoft deployment of the OCSP protocol. This feature, coupled with the new OCSP answering service, is a big boost compared to CRL based revocation. The client's OCSP client has been redesigned for the schema, plus an OCSP resp

Fortunately, Sharepoint solution generator reduces the complexity of creating site definition to some extent. But I personally suggest you use the first method. :) So today I will first introduce feature stapling.Article.

under this scheme: Man-in-the-middle attack and information repudiation. 3.2 Authentication-ca and certificatesThe key to resolving the above authentication problem is to ensure that the public key path obtained is legal and capable of validating the identity of the server, which requires the introduction of an authoritative third-party agency CA. The CA is responsible for verifying the information of the owner of the public key and issuing the certificate of authentication, as well as providin
