To understand better, here is what happens when a web browser is connected to a secure website that is SSL certified:
- The browser of a PC requests a secure page (this usually starts with https).
- The server sends the public key along with a certificate.
- The browser then checks the certificate and identifies the third party who has issued the same. The validity of the certificate and how it is related to the site is determined.
- The browser than uses the public key to encrypt the encryption key and the same is sent to the server with the secure URL and the relevant data.
- The web server then decrypts the encryption key and uses it to decrypt the URL and data.
- The server sends back the document and the data is encrypted with the symmetric key.
- The final step is that the browser decrypts the http data and the html document with the help of the key and the information is shared successfully.
