Hyper-Text Transfer Protocol Secure (HTTPS)

Hypertext Transfer Protocol Secure (HTTPS) is a secure version of the Hypertext Transfer Protocol (HTTP) used by websites to streamline communication between the client (website visitor) and the server. It facilitates the secure transmission of data, using encrypted channels via Transport Layer Security (TLS) or Secure Sockets Layer (SSL).

HTTPS protects data integrity by using message authentication code (MAC) to ensure that data is received in its original form, mimicking the original intention. It also prevents interception of data by third-party actors as the data is transmitted and ensures that the website visitors are truly connected to the correct site instead of a malicious one.

When a HTTPS connection is established, the web browser and server exchange a public key and an encrypted digital certificate. This certificate contains information such as the domain owner’s identity, the digital signature of the issuer, the protocol used, the encryption level, and the expiration date. If the web browser trusts the certificate, it will send an acknowledge message to the server. A secure connection between the web server and the web browser will then be established.

HTTPS makes the use of Hypertext Transfer Protocol (HTTP) more secure for the client and the server. It provides protection of online data transmissions, reducing the risk of data being exposed or manipulated by malicious actors. By using HTTPS, websites and online services gain an additional layer of security and trust.
