HTTPS is the encrypted variant of HTTP. The browser establishes a link to a server on a standard port, just as it does with HTTP. Secure Sockets Layer, or SSL, is used to transport data in the additional layer of HTTPS protection. The web address can be used to determine if a site uses the HTTPS protocol. HTTP does not have SSL, while HTTPS does, which encrypts your data and secures your connections. HTTPS also includes the TLS (Transport Layer Security) protocol, which HTTP does not have. HTTPS is a more stable version of HTTP than HTTP.
