Editor to share with you whether SSL encryption can really ensure security, I hope you can learn a lot after reading this article, let's discuss the methods together!

Now as long as you use a Chrome browser to visit any HTTP site, Chrome will display an "unsafe" warning on the address bar.

Why does Chrome think the website is not secure? The reason is that the site uses the HTTP protocol.

So why is the HTTP protocol insecure? The reason is that the HTTP protocol adopts the mode of data plaintext transmission. The user submits the data from the client browser, and the data is transmitted through the network to the website server in clear text. If in the process of network transmission, a third party invades the network and intercepts the data packet, then the data content transmitted by the user will be completely obtained by the interceptor. If what the user transmits is personal private information such as bank card, password, that is very disadvantageous to the user. And the website server can not know whether the user data will be tampered with in the process of data transmission, which is also a great risk to the website server.

The solution to this problem is to use the HTTPS protocol to encrypt your website. We have talked about what HTTPS encryption is before. Install a server certificate for your web server and the website can be accessed using the HTTPS protocol. Websites that use HTTPS protocol will encrypt user data with HTTPS (that is, SSL encryption) in the process of data transmission, and then transmit the encrypted data through SSL, so even if it is intercepted by a third party, it can ensure the security and integrity of user data. That's why the HTTPS protocol is considered secure and reliable.

What are the types of SSL certificates?

There are mainly three types of certificates: EV, OV and DV:

Why can SSL encryption be secure?

SSL encryption is based on asymmetric encryption algorithm. An asymmetric encryption algorithm produces a pair of long strings called key pairs (public key, private key). After the data is encrypted with the public key, it can only be unlocked using the private key. The website that installs the server certificate actually saves the private key in the server, and makes a SSL certificate with the public key together with the relevant information of the website (such as domain name, owner name, validity period), and publishes the SSL certificate to the Internet.
