First what is HTTPS? HTTPS, or “secure http”, was developed to allow authorization and secured transactions. Exchanging confidential information needs to be secured in order to prevent unauthorized access, and https makes this happen. The ‘S’ at the end of HTTPS stands for ‘Secure’. It means all communications between your browser and the website are encrypted. When an SSL certificate is used, the information becomes unreadable to everyone except for the server you are sending the information to.
