When we browse some websites, something similar to the above picture will appear. When the warning message "unsafe" appears on the website, it means that the website has no https certificate installed, because one advantage of https certificate is that it is trusted by major browsers, but this will not happen if it is installed.
Malicious incidents such as account password theft and bank card balance theft often occur on the Internet. These may all be because the information was stolen by hackers when browsing some unsafe website login account passwords. Https is different from the previous http, it is transmitted in the form of ciphertext, so one of the functions of https certificate is to authenticate the server and protect the security of data transmission. If you visit a website with https installed, you can rest assured, because https can prevent private information from being stolen and tampered with, prevent phishing websites and create a safe network environment.
