The public key is shared with client devices via the server's SSL certificate. TLS uses a technology called public key encryption: there are two keys, a public key and a private key. HTTPS uses TLS (or SSL) to encrypt HTTP requests and responses, so instead of the plaintext, an attacker would see a series of seemingly random characters. HTTPS stands for Hypertext Transfer Protocol Secure (also referred to as HTTP over TLS or HTTP over SSL). The answer to above security problem is HTTPS. Essentially, a malicious actor can just read the text in the request or the response and know exactly what information someone is asking for, sending, or receiving, and even manipulate the communication. This could be a password, a credit card number, or any other data typed into a form. This is especially an issue when users submit sensitive data via a website or a web application. The problem is that anyone monitoring the connection can read these plaintexts. HTTP requests and responses are sent across the Internet in plaintext. HTTP responses are answers to HTTP requests. These HTTP requests go to either an origin server or a proxy caching server, and that server will generate an HTTP response. For example, if a user clicks on a hyperlink, the browser will send a series of 'HTTP GET' requests for the content that appears on that page. HTTP requests are generated by a user's browser as the user interacts with web properties.

There are two main kinds of HTTP messages: requests and responses.

What is an HTTP request and how does it work? Most information that is sent over the Internet, including website content and API calls, uses the HTTP protocol. HTTP stands for Hypertext Transfer Protocol, and it is a protocol-or a prescribed order and syntax for presenting information-used for transferring data over a network.

A website that uses HTTP has HTTP:// in its URL, while a website that uses HTTPS has HTTPS://. As a result, HTTPS is far more secure than HTTP. The difference between the two protocols is that HTTPS uses TLS (SSL) to encrypt normal HTTP requests and responses.
