Generally, the Registry controls the exchange of subjects, final entities, and PKI during registration, certificate transfer, and other key and certificate lifecycle management processes, however, Ra does not initiate a trusted statement about the subject in any environment

I. Theoretical knowledge What is ca? Ca is short for Certificate Authority. It is usually translated into an authentication authority or a certification center. It is mainly used to issue digital certificates to users. This digital certificate contains part of the user's identity information and the public key held by the user. At the same time, the private key of the CA is used to add a digital signature to the digital certificate. If other users can verify that the certificate is true, in ad

Digital certificates provide electronic authentication for the secure communication between the two parties. In the Internet, corporate intranet or extranet, the use of digital certificates for identification and electronic information encryption. The digital certificate contains the identification information of the owner of the key pair (public key and private key) to authenticate the identity of the certificate holder by verifying the authenticity of the identified information.Certificate app

, certificate approval and CancellationManagement System. The CA hierarchy can be divided into the authentication center (Root CA), Key Management Center (km), authentication subordinate Center (sub-Ca), and certificate approval Center (RA center) certificate approvalPoint (rat) and so on. In general, the CA center should issue a certification system statement, and solemnly declare the CA policy, security measures, service scope, service quality, resp

. The PKI system presented in the later chapters provides a complete set of certificate management frameworks. PKI system PKI (public Key Infrastructure) system does not represent one kind of technology, but is a framework and specification of integrating multiple cryptographic methods to realize safe and reliable transmission of message and identity. In general,

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
