I. Introduction of OpenSSL
OpenSSL is currently the most popular SSL cipher library tool that provides a common, robust, and fully functional suite of tools to support the implementation of the SSL/TLS protocol.Official website:
In HTTPS learning note two, the concept of digital certificates has been clarified, composed and how the client validates the server-side certificate during the HTTPS connection process. This chapter describes how to use the OpenSSL library to
SSL security certificates can be generated on their own or through a third-party CA (certification authority) Certification Center payment request. SSL security certificates include: 1, CA certificate, also called root certificate or intermediate
OpenSSL is an open source SSL implementation. The simplest and most important application based on the OpenSSL directive is to use Req, CAs, and X509 to issue a certificate.OpenSSL provides command-line options and interactive two ways to perform
OpenSSL req is used to generate a certificate request for a third party authority CA to issue and generate the certificate we need. The Req command can also invoke the X509 command for format conversion and display information such as Text,modulus
In cryptography, CA (Certificate Authority) refers to an organization trusted by multiple users, which can create and assign public key certificates.For the sake of standardization, we will first introduce the terms that may be involved in this

Background
Due to the heart of openssl recently, I changed the ssl library 1.0.1g. I need to use this library to connect to the server. However, after I find that the Library is replaced, for some domain names, the ssl handshake will fail. In order
