Explain the reason:
After the SSL certificate is installed on the website, using the https encryption protocol to access the website can activate the SSL encryption channel (SSL protocol) between the client browser and the website server, realize high-intensity two-way encrypted transmission, and prevent the transmitted data from being leaked or tampered with. After the website deploys the global trusted SSL certificate, the browser has built-in security mechanism to check the certificate status in real time, and display the website authentication information to users through the browser, so that users can easily identify the real identity of the website and prevent phishing websites from counterfeiting.
If you use EV certificate browser to display green address bar, green "lock" security sign, super 256-bit encryption protection, company name and certificate authority name.
Websites with SSL certificates will display an HTTPS green security lock in the browser address bar. It can tell users that they are visiting a safe and reliable website, and they can operate and trade with confidence, effectively enhancing the brand image and reputation of the company.
Through the comparative test between HTTP and HTTPS, it shows that the new generation HTTP2 protocol using SSL certificate can access websites much faster than websites using HTTP protocol.
Through the promulgation of Baidu announcement, it is clearly pointed out that search engines will give priority to websites that adopt HTTPS protocol for ranking.
After the website uses HTTPS protocol, SSL certificate can authenticate the real identity of the server, thus preventing phishing websites from being forged.
Solution: you can get a cheap HTTPS certificate at Gworg.
