What is HTTP/HTTPS?

Description

The Hypertext Transfer Protocol (HTTP) is an application protocol for distributed, collaborative, and hypermedia information systems.HTTP is the foundation of data communication for the World Wide Web and commonly used on TCP for exchanging or transferring hypertext. Hypertext is structured text that uses logical links (hyperlinks) between nodes containing text. HTTP resources are identified and located on the network by Uniform Resource Locators (URLs). URIs and hyperlinks in HTML documents form inter-linked hypertext documents.

HTTP Secure (HTTPS) is an extension of the Hypertext Transfer Protocol (HTTP) for secure communication over a computer network.In HTTPS, the communication protocol is encrypted using Transport Layer Security (TLS), or formerly, its predecessor, Secure Sockets Layer (SSL). The protocol is therefore also often referred to as HTTP over TLS, or HTTP over SSL.The principal motivation for HTTPS is authentication of the accessed website and protection of the privacy and integrity of the exchanged data while in transit. It protects against man-in-the-middle attacks. The bidirectional encryption of communications between a client and server protects against eavesdropping and tampering of the communication.
