HTTPS is HTTP with encryption. The difference between the two protocols is that HTTPS uses TLS (SSL) to encrypt normal HTTP requests and responses. HTTPS is far more secure than HTTP.
HTTP or the Hypertext Transfer Protocol is the foundation of the World Wide Web, and is used to load web pages using hypertext links. It is also called “a stateless system”, which means that it enables connection on demand. It is a protocol – or a prescribed order and syntax for presenting information – used for transferring data over a network. Most information that is sent over the Internet, including website content and API calls, uses the HTTP protocol. There are two main kinds of HTTP messages: requests and responses.
HTTPS or Hypertext transfer protocol Secure uses TLS (or SSL) to encrypt HTTP requests and responses. It is the primary protocol used to send data between a web browser and a website. This is particularly important when users transmit sensitive data, such as by logging into a bank account, email service, or health insurance provider.
