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)

1.A and B transfer data via SSL approximate processPrivate key encrypted data can only be decrypted by its own corresponding public key.The CA Visa authority first sends itself a certificate, a publicly recognized institution,The communication data between a B is encrypted by the private key generated by itself.First, a the public key of their name and address is sent to the CA, the data is called AA,The

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
