A protocol is an instruction or a set way of doing something. On the internet, the Internet Engineering Task Force determine the protocols for how actions are carried out online. This post will explain the following protocols: HTTP, HTTPS, TLS and SSL.
HTTP – HyperText Transfer Protocol
HTTP is a set of standards that allows internet users to exchange/ transfer data between web browsers and web servers.
HTTPS – HyperText Transfer Protocol with Secure Socket Layers
HTTPS is similar to HTTP but with a security extension. It is encrypted using Secure Sockets Layer which prevents anyone tampering with the browser’s communications with other web-pages.
TSL – Transport Layer Security
TSL is a cryptographic protocol that provides communication security over computer networks. It is used in a variety of applications, such as email, instant messaging and web browsing. Websites use TSL to secure all communications between their web browsers and their servers.
SSL – Secure Sockets Layer
Similar to TSL, SSL ensures that all data passed between a web server and a web browser remains private. It does this by establishing an encrypted link between browsers and web servers. When you create an SSL connection, you will be prompted to complete security questions and then your web server will create two cryptographic keys: a private key and a public key.
