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. Experiment concept:
When we access some finance and other websites with high security, it is no longer an ordinary http connection, but an https connection. This s indicates that the communication is encrypted, this requires the CA to issue a digital certificate to verify the correctness of the WEB server. This digital certificate provides electronic authentication for

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
