This ensures the legitimacy of the connection. When an SSL certificate is present the address of the website will contains the word https to indicate that information is securely transmitted.
How do SSL Certificates work?
SSL Certificates work using a concept called public key cryptography. Public key cryptography uses 2 long strings of randomly generated numbers, called the private key and public key. The public key is known to the server and accessible by anybody. When a website transmits information to the server it uses this public key to encrypt the message. However, the encrypted message can only be unscrambled with the private key that is isolated to the server. When a server receives information from a website it applies this private key. In this way, SSL certificates prevent unauthorized access of information. A hacker that intercepts messages to the server will be left with a code that they will be unable to break.
