HTTP is an acronym for hyper text transfer protocol. It's main purpose is to transmit and receive information over the Internet. It is a common standard that is followed by all agents across the Internet so that data can be shared across diff erent servers. HTTP is commonly and widely used for interpreting html pages. But there are some instances wherein certain clients may require transmitting confi dential data.
Such data must be secured and unauthorized access must be prevented. Taking this into consideration, Netscape Corporation developed HTTP secure, commonly known as HTTPS. HTTPS interprets data in a similar way as HTTP, i.e. it uses the same rules as well as URL scheme. The only diff erence is that HTTPS encrypts data that is sent and received. The default port for http is 80 and for https is 443. Also, there are two types of encryption layers i.e. Transport Layer Security (TLS) and Secure Sockets Layer (SSL). When an HTTPS connection is used, the server responds by displaying a list of encryption methods. The client will then select a method and exchange certificates for identifi cation and authentication purposes. Once this is done, encrypted data is transmitted and received between the client and the server. HTTPS is normally used for pages of banking websites.
