At present, the HTTP protocol is most widely used in the website, which is used to transfer hypertext from the www server to the local browser. It can make the browser more efficient and reduce the network transmission. However, it has a big disadvantage: all the information and data in the transmission process are plaintext, and the transmission in the network is very easy to be intercepted or tampered with, which is very insecure.

But starting in 2018, that will change. Starting in October, Google will display a clear "unsafe" message in its browser for sites visited through HTTP. For visitors, unsafe warnings are likely to cause them to shut down your site immediately, which increases the bounce rate and reduces sales and conversion rates.

HTTPS is a HTTP channel with the goal of security, which can improve the security factor of HTTP protocol by adding SSL layer. So the security foundation of HTTPS is SSL, which can be realized by installing SSL security certificate to the website. Then again, SSL certificates are now very important to corporate websites.

SSL certificate provides authentication to users and servers by establishing a SSL secure channel (Secure socket layer) between client browsers and Web servers, encrypts and hides the transmitted data, ensures that the data is not changed during transmission, and ensures the integrity of the data.

Because SSL technology is built into all major browsers and WEB server programs, you only need to install the server certificate to activate this feature. That is, it can activate the SSL protocol, realize the encrypted transmission of data information between the client and the server, and prevent the leakage of data information. It ensures the security of the information transmitted by both parties, and the user can verify whether the website he visits is true and reliable through the server certificate.

Secondly, by encrypting information and providing authentication, SSL certificate technology can not only show the authenticity of the website, but also encrypt the information when the website user enters a password and user name without being intercepted by * *. Even if it is a ciphertext, the real user name and password can not be seen. The networks we often encounter, such as data hijacking and phishing, are caused without the protection of SSL certificates. This is very likely to lead to the disclosure of user information and even cause serious economic losses, which can be effectively avoided by SSL certificate authentication, because only authorized users can read data.

With the popularity of the network, the demand for SSL certificates in the network security environment is increasing day by day. At present, 84% of the world's top 500 companies and 88% of the world's 100 largest banks and 46 of the world's 50 large e-commerce websites have installed SSL certificates. Only when the enterprise deploys the SSL certificate, can it really give netizens a reassuring trading platform.
