HTTTPS - secure data transfer

HTTPS is a secure version of HTTP protocol. HTTPS needs to be used whenever sensitive or private information is transmitted. For example HTTPS needs to be used in login pages or pages that contain financial information.

HTTPS uses certificates that can be used to verify if the SSL certificate belongs to the address that a user attempts to use. If there is a mismatch between the address in the certificate and the address that a user attempts to use, then a browser displays a warning message.

Encrypting the data comes at higher CPU utilization.

Some companies choose to encrypt all web traffic to be on the safe side.
