OpenSSL Toolkit is one of the implementation methods of SSL v2/V3 and TLS v1 protocols on Linux, and provides common encryption and decryption functions. OpenSSLIt consists of three parts: 1:Libcrypto: an encrypted library mainly used to implement encryption and decryption. 2:Libssl: implements the SSL server-side function session Library 3:OpenSSL command line tool:/usr/bin/OpenSSL This document only describes how to use the OpenSSL command to create a private

First, the HTTPS service must be built with an HTTPS certificate. This certificate can be viewed as an application-level certificate. The reason for this is that the HTTPS certificate is generated based on the CA certificate. For official websites, CA certificates require a qualified third-party certification authority to apply for access. For some of our self-built small projects, you can use your own serv

Objectivewith the rapid development of Internet, network communication has become the main way to transmit information. While the communication of data transmission is mostly Ming wen Transmission, in the network of this insecure environment, if there is no set of data encryption mechanism, will lead to sensitive information and important data leakage, causing immeasurable loss. and OpenSSL just made up for this shortcoming, what is OpenSSL? OpenSSL is a powerful set of cryptographic components

1 CA Introduction Ca is the certificate issuing authority and is the core of PKI. Ca is the authority responsible for issuing certificates, certification certificates, and managing issued certificates. It requires policies and specific steps to verify and identify user identities, and sign user certificates to ensure the identity andPublic Key. For example, Alice

encrypts the communication between the browser and the server. The main differences between HTTPS and HTTP are the following four points: The HTTPS protocol requires a certificate to be applied to the CA, and the general free certificate is very small and requires a fee. HTTP is a Hypertext Transfer Protocol, the information is plaintext transmission, HTTPS is a secure SSL encryption transport protocol. HTTP and HTTPS use a co

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

With the increasing popularity of e-commerce and e-government, problems such as theft and tampering of important data and files during transmission, network fraud, and network attacks also emerge, only by establishing a network security assurance system can online activities be improved. The CA technology is the core technology to ensure network security. About ca 1. What is

checksumAnother question is how Bob and Alice get the other's public key, or how to prove that the public key they get is the other. This requires the introduction of the other certification authority CA, which is an explanation between the certification authority and Bob/aliceBlack box C: Represents the public key, organization, address, and other information to be issued to the Bob/aliceBlack box D: is a one-way encryption of black box C to get the
