We know that when a client establishes a session with the server, the client first sends the request, then tpc/ip the three handshake, and the client establishes an SSL session with the server side.The session process is as follows :650) this.width=650; "Src=" Http://upload-images.jianshu.io/upload_images/6908438-67216e55243d62ce.jpg?imageMogr2 /auto-orient/strip%7cimageview2/2/w/1240 "style=" height:auto;vertical-align:middle;border:0px; "alt=" 1240 "/>In short, it is:The first step: the client

I have studied SSL/TLS some time ago and read the English version of Eric rescorla's SSL and TLS-designing and building secure systems (for the severity of the Chinese version, I wrote a previous articleBlog has been severely criticized ). The author of this book follows the idea of Steven s in his role of TCP/IP authentication strated: us
ensure the privacy of the data ;3 . Decrypt the signature of the original data with the public key provided by Alice and verify the identity of the data sender Alice;4, using the same one-way encryption algorithm to calculate the original data signature and the decrypted signature to compare, ensure data integrity. In the process of data transmission, it is necessary for both parties to obtain the other's public key, that is, the key exchange, the public key in the network transmission process
Ca:certificate Authority, a certificate authority, also known as a certification authority or certification center, is a trusted third-party entity in a PKI. Responsible for several important tasks such as certificate management tasks such as certification issuance, revocation, update, and renewal, and CRL publishing and event logging. First, the principal issues the certificate request, typically, the principal generates the key pair, and sometimes the CA
I learned how to use OpenSSL in Linux over the past two days. OpenSSL is an open-source encryption tool. In Linux, we can use it to build a CA to issue certificates, encryption tools that can be used within an enterprise. Before introducing OpenSSL, first describe how to implement "Identity Authentication + Data Encryption.
For how to implement "Authentication + Data Encryption", please refer to the following flowchart (self-drawn, relatively simple)
by B and identity authentication is realized. (Assume that the decrypted signature is fcode)
(4) A uses the same one-way encryption algorithm to extract the signature of the received original message. Use this pattern to compare with the obtained fcode. If the same pattern is used, it indicates that the data of the original packet is complete.
Problem: the above method ensures data integrity, identity authentication, and data confidentiality. The public key of the other party must be used d

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
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

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

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.
