How do SSL Certificates work?
A browser requests a secure page (usually https://).
Once secure transaction is initiated. The web server sends it's public key with it's certificate.
The browser checks that the certificate was issued by a trusted party (usually a trusted CA such
as Comodo), that the certificate is still valid and that the certificate is related
to the site contacted.
The browser then uses the public key, to encrypt a random symmetric encryption key and sends it to
the server with the encrypted URL required as well as other encrypted http data.
The web server decrypts the symmetric encryption key using it's private key and uses the
symmetric key to decrypt the URL and http data.
The web server sends back the requested html document and http data encrypted with the symmetric key.
The browser decrypts the http data and html document using the symmetric key and displays the information.
