HTTPS (Hypertext Transfer Protocol Secure) is a secure version of HTTP that uses SSL/TLS encryption to establish an encrypted link between a web server and a browser. This secure connection ensures that all data transmitted between the two parties is encrypted and secure from eavesdropping and tampering.

Key Features of HTTPS

  • Encryption: HTTPS uses SSL/TLS encryption to protect data transmitted over the network. This means that any data intercepted by attackers will be unreadable.
  • Authentication: HTTPS ensures that the data is sent to the intended recipient and not to an imposter. This is achieved through the use of digital certificates.
  • Data Integrity: HTTPS ensures that the data sent between the server and the browser has not been altered during transmission.
  • Confidentiality: HTTPS keeps the data confidential and secure, preventing unauthorized access.

How HTTPS Works

  1. Handshake: The client (browser) and server establish a secure connection through a handshake process. This involves the exchange of encryption keys and certificates.
  2. Encryption: Once the handshake is complete, the data transmitted between the client and server is encrypted using the agreed-upon encryption method.
  3. Data Transmission: The encrypted data is transmitted between the client and server, ensuring that it remains secure.

Why Use HTTPS?

  • Security: The primary reason to use HTTPS is to ensure the security of data transmitted over the network.
  • Trust: HTTPS builds trust with users by ensuring that their data is secure and that they are communicating with the intended recipient.
  • SEO: Google has confirmed that HTTPS is a ranking signal, meaning that websites using HTTPS may rank higher in search results.
