The encryption protocol SSL (short for: Secure Sockets Layer) is designed to provide a secure data transmission via Internet. The protocol ensures an asymmetric encryption for the connection between a server and a browser as well as the safe transfer of unencrypted communication protocols like HTTP (web), POP3 or IMAP (e-mail). Such a secure connection is active, if the browser’s address bar begins with a “https” instead of the usual “http”. By using techniques like Public Key Encryption, the SSL creates a certificate which contains information about the server. The SSL protocol provides authentication of the server with which the browser communicates to ensure its legitimacy.
