SSL or Secure Sockets Layer is a security protocol that uses modern encryption for sending as well as receiving sensitive information all over the internet. It works by creating a secure channel between a user’s browser as well as the site’s server to which the user wants to connect to and then any information that passes through this secure channel is encrypted at one end as well as decrypted upon receipt on the other end. Therefore, even if someone this information, it won’t be on any use to them because of the encryption of the information.
Sites can enable SSL by getting an SSL certificate. Browsers can detect this certificate, which lets them know that this connection needs to be encrypted. It is very easy for users to recognize whether they are visiting an SSL-enabled site or not by spotting a tiny lock preceding the website URL. Also, sites using SSL are identifiable via their use of the https instead of http.
