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

Encryption, decryption, and OpenSSL private CA I. Common Algorithms Common encryption algorithms and protocols include symmetric encryption, asymmetric encryption, and one-way encryption. 1. symmetric encryption: one key is used for encryption and decryption. algorithms can be made public and keys cannot be public, because encryption relies on keys. Security depends on keys rather than algorithms; Common algorithms: DES (Data Encryption Standard, 56 b

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
