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/

What is OpenSSL?OpenSSL is a well-known open source Cryptography Toolkit for secure communications, including key cryptographic algorithms, common passwords, and certificate encapsulation capabilities.1. OpenSSL websiteOfficial: https://www.openssl.org/source/2. Windows installation methodThe

If you want to create a self-signed certificate that is not valid for one year, or provide additional information about yourself, you can use Open SSL to create a certificate, instead of the standard tool that comes with the SDK: makekeys. The following command demonstrates how to create a self-Signed key/certificate

the upper-level Ca, the complete CA certificate chain must be provided to OpenSSL in the future. So our work is not complete yet. Next we will construct such a CA certificate chain. In fact, it is very simple to append the Root CA certificate to the intermediate CA certificate. In the production environment, CA certificates at all levels are public. Therefore, you can append the certificates in sequence to generate a file called "CA certificate cha
