I. INTRODUCTION OpenSSL is an open-source encryption tool. in a Linux environment, we can use it to build a CA for certificate issuance. it can be used in an enterprise's internal encryption tool, the following is a powerful OpenSSL tool. in Linux, a CA is built to implement Certificate Management. II. Build 1. First, let's take a look at the CA directory structu

Building private CAs and SSH configuration servicesBefore you learn how to build a private CA, familiarize yourself with the basic concepts: CAS represents a certification authority, PKI represents a public key infrastructure, a registry of RA certificates, and a revocation list for CRL certificates. There are some encryption methods involved in architecting the CA, and here are some types of encryption to

; SSL: (Secure Socket Layer) Secure Socket Layer, which provides key transmission over the Internet. Its main goal is to ensure the confidentiality and reliability of the communication data between two applications. It is an encryption algorithm that can be supported at the same time on the server side and the client side. Currently, SSLV2 and SSLV3 are mainstream versions ).The following figure shows how to implement the SSL function. Before introducing it, let's talk about what functions SSL
