After a lot of groping experiments I finally succeeded in achieving the SSL certificate authentication function, so I think this time I want to record these steps for future reference. For security and convenience reasons, I want to sign a client's certificate on a separate dedicated machine, also known as a Certificate Certification center (CA). This allows us to authorize new clients without having to log on to the PostgreSQL server before signing

We know that before the client establishes a session with the server, the client sends the request first, then tpc/ip the three handshake, and then the client establishes an SSL session with the server side. Session Process: A--> Server Side B--> Client The first step: AB both discuss the use of what encryption algorithm, how to encrypt and so on. Step two: A send a certificate to B, in order to make B believe him. Step Three: B believe, generate the symmetric key, send the request page to a

Overview of CSMA/CA protocol analysis the MAC protocol 802.11 of the wireless LAN standard is very similar to the MAC protocol 802.3 standard. In the 802.3 protocol, the MAC protocol uses a mechanism called CSMA/CD (Carrier Sense Multiple Access/Collision Detect), that is, the Carrier listens to Multiple Access/conflict detection mechanisms. This Protocol resolves how to detect and avoid network conflicts when two or more network devices need to trans

Everybody, although this has nothing to do with autoproxy, it is a very serious security threat to all (including autoproxy) users. Me, wcm, Autoproxy author. It is strongly recommended that you carefully read and take measures in your personal reputation.Background Any information transmitted online may be maliciously intercepted. Even so, we still store a lot of important information on the Internet, such as private emails and bank transactions. This is because there is something that calls SS

First, what is CACA (Certificate authority) is the abbreviation of digital Certificate Certification Center, refers to the issuing, management, abolition of digital certificate institutions. The role of a CA is to check the legitimacy of the identity of the certificate holder and issue a certificate (signed on the certificate) to prevent the certificate from being forged or tampered with, and to manage the certificate and key.Second, why use CACA is t

1. Preface Because we need to do some development on Ca, we need to do some research on Ca SDK. The following is a brief introduction. 2. Version NSM uses version 3.1 3. Detailed introduction The ca sdk mainly includes three aspects: worldview API, Agent API, and enterprises management API. Currently, worldview APIs and elastic ISES Management APIs are used

First, generate certificate signing Request (CSR) in IIS Personal understanding: The generation of a CSR is the creation of a "private/public key pair" from which the public key is extracted. 1. Open IIS Manager, select Server certificates in the root node, click the Create certificate Request on the right ..., and then fill in the corresponding distinguished Name Properties (see figure below). Common name to fill in the domain name (if used for all level two domain name, fill *. domain nam

How does OpenSSL implement private CA. NOTE 1: The blue part is the main process, and the yellow arrow points to the specific operation steps. What is OpenSSL? 1. A security protocol that provides security and data integrity for network communication, including key algorithms, common key and certificate encapsulation management functions, and SSL protocols, and provides a wide range of applications for testing or other purposes; 2. OpenSSL is only a
