Hyper Text Transfer Protocol Secure Hypertext Transfer Protocol Secure (HTTPS) is an extension of the Hypertext Transfer Protocol HTTP. It is used for secure communication over a computer network, and is widely used on the Internet. In HTTPS, the communication protocol is encrypted using Transport Layer Security (TLS) or, formerly, Secure Sockets Layer (SSL). The protocol is therefore also referred to as HTTP over TLS, or HTTP over SSL.
Its just HTTP but with [[TLS]] security HTTPS URLs begin with “https://” and use port 443 by default, whereas, HTTP URLs begin with “http://” and use port 80 by default.
HTTP is not encrypted and thus is vulnerable to man-in-the-middle and eavesdropping attacks, which can let attackers gain access to website accounts and sensitive information, and modify webpages to inject malware or advertisements. HTTPS is designed to withstand such attacks and is considered secure against them (with the exception of HTTPS implementations that use deprecated versions of SSL).
