Authentication and encryption
Encryption is the mechanism to mangle your conversation (or data) so that it only makes sense to the receipient. There are various ways to encrypt data. Encrypted data is transferred over the world wide web using SSL (https).
Whenever you start an SSL session with a website, the browser first checks the certificate on the server to ensure that it is really the server it is claiming to be. If either the certificate name and the server name doesnt match or the certificate has expired, it will usually pop-up a dialog box informing you of the problem and asking you whether you still want to accept the certificate.
