Imagine you’re on a bus having a conversation about your sensitive financial data with your bank account manager, or chatting about 
personal details with a friend. Everything you say can easily be heard by anyone around you. This is how the Internet would look like without SSLs – it’s like you’re saying your bank account number, passwords, or secret love confessions out loud for all to hear. Sounds terrifying, right? An SSL certificate, in this context, would allow you to speak a language that can be understood only by you and the party to which you’re speaking. To the other “passengers” around you, however, it would sound like a white noise.
