Then how does the website certificate ensure the information security? In the process of practical use, the website shows the public key to the user, and the private key is saved by itself. In the process of data transmission, the information is encrypted according to the algorithm. Before this information reaches the web server, it is only a string of "garbled" strings. When lawbreakers intercept this information, the information cannot be restored because there is no corresponding private key, and the information reaches the server and is decrypted with the private key. You can get a complete piece of information, which ensures the security of the information while ensuring that this piece of information transmitted by the user will not be obtained by others. Similarly, when the web server sends out a message, because after encryption, the public key is required to decrypt the message, if you use the public key to decrypt the message, it means that the publisher of the message is the website. If you can't unlock this piece of information, it means that it was not released by this website. In this way, it is tantamount to giving the website an "ID card", which can neither escape nor camouflage, so that users can safely rest assured to use such a function.
