What is HTTPS?
HTTPS is the secure version of HTTP. If a URL contains “https” instead of “http”, it means that website uses encryption and/or authentication methods to secure its connection. Any time sensitive information is viewed or entered on a web page, the user should ensure the URL is prepended with “https://”.
How does HTTPS work?
SSL/TLS, or secure sockets layer/transfer layer protocol, is the most common cryptographic protocol used to encrypt secure communications on the web.
Besides encrypting the information being sent between client and server, HTTPS also authenticates both parties using a public-key system to prevent imposters from intercepting communications.
