How does the browser determine that the public key is incorrect?

The browser verifies the issuer

Browsers check that a certificate's issuer field is the same as the subject field of the previous certificate in the path. For added security, most PKI implementations also verify that the issuer's key is the same as the key that signed the current certificate.

How does a server validate a security certificate?

The web server sends a copy of the SSL certificate to the browser. The browser checks the authenticity of the certificate and sends a message to the webserver. In return, the webserver/website sends a digitally signed acceptance for initiating an SSL encrypted session.

How do browser certificates work?

The web server sends the browser/server a copy of its SSL certificate. The browser/server checks to see whether or not it trusts the SSL certificate. If so, it sends a message to the web server. The web server sends back a digitally signed acknowledgement to start an SSL encrypted session.

How does a browser trust a website?

Browsers are shipped with a built-in list of trusted roots, called a trust store. A trust store is a collection of root certificates that are trusted by default and are maintained by the companies that make operating systems and web browsers, such as Apple, Microsoft, Mozilla, and Google.

How a client's browser checks the authenticity of a certificate that was sent by a server during a TLS handshake?
