Today, I found that when using a google browser to access the HTTPS URL, click Mini Lock-- > > Connect-- > is there a server that does not provide any certificate transparency information? Only google browsers have this hint, and no other browsers have this hint! What is Certificate Transparency Certificate Transparency?

Certificate transparency Certificate Transparency is a transparent censorship technology proposed by Google to ensure the security of the certificate system. Google browser will display the green unit name only if it supports the EV SSL certificate issued by CT technology, otherwise the chrome browser will not display the green unit name.

Certificate transparency is a new specification for Google to reduce malicious issuance of unauthorized certificates. CA created a "pre-certificate" and sent it to Log Server (log server) certified by Google. The log server returned a "signed certificate time stamp" (Signed Certificate Timestamp) to the pre-visa to CA, called STC data. This data is embedded in an officially issued certificate or deployed to a Web server through TLS schema provision. To put it simply: to make a whitelist of legally issued certificates, Google browser will also check to see if the certificate is on the whitelist when verifying the certificate. If not, the green unit name will not be displayed, and the certificate transparency information will not be displayed.

Certificate transparency, like the transparency of many other actions or industries, helps build user confidence, ensure that website visitors are not harmed by malicious or incorrect SSL certificates, bring more traffic and revenue to the site, enhance the trust of online users, and facilitate more online orders.
