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

The previous article introduced some basic questions about SSL two-way authentication and used nginx + PHP to build https-based WebService. The previous method only implemented the mode. Yesterday, my colleagues continued to implement the N: 1 mode. Here I will record it again. Because the ssl_client_certificate parameter of nginx can only specify one client public key, if a client is added for communication, a server is required. The N: 1 mode is implemented through the CA cascade certificate m

the previous approach was just to implement the 1:1 pattern, and yesterday colleagues continued to implement the N:1 model, and here I'm going to sort it out. Since Nginx's ssl_client_certificate parameter can only specify a client public key, it is necessary to re-match a server if a client is added to communicate. The N:1 pattern is implemented through the CA's cascading certificate pattern, first generating a set of CA root-level certificates and then generating level two certificates as cl

public key encryption is that a key pair replaces a large number of symmetric keys, thus reducing the workload of key management. Digital Certificates further enhance this advantage, which solves the issue of public key distribution and management. However, digital certificates cannot be managed by themselves. Due to the inherent widespread distribution of digital certificates, the distribution of digital certificates must be taken into account when designing management schemes for these certif
