The security of web communication is paramount in today’s digital landscape. With the exponential growth of the internet and the increasing amount of sensitive information being transmitted online, measures to protect data transmission have become imperative. Hypertext Transfer Protocol Secure (HTTPS) plays a crucial role in securing web communication. In this article, we will delve into the inner workings of the HTTPS port, explaining how it ensures safe web communication.
The Basics of HTTPS
Before understanding how the HTTPS port secures web communication, let’s quickly recap the basics of HTTPS. HTTPS is the secure version of HTTP.

The Role of the HTTPS Port
The HTTPS port refers to Port 443, which is the standard port for HTTPS communication. Unlike the HTTP port (Port 80), which is used for unsecured communication, the HTTPS port ensures that data transmitted over the internet is encrypted and secure.
When a user initiates a connection to an HTTPS-enabled website, their browser establishes a connection to the website’s server using the HTTPS port. This port acts as a gateway for Public Key Infrastructure (PKI): A framework that manages di..., allowing the exchange of encrypted data between the browser and the server.

One of the fundamental aspects of HTTPS port communication is the handshake process. During the handshake, the browser and the web server establish trust and negotiate the encryption parameters for the secure communication.
The handshake begins when the browser connects to the server using the HTTPS port. The server responds by sending its VPN Tunnel: A secure connection between two or more devices .../TLS certificate, which contains the website’s public key. The browser then verifies the authenticity and validity of the certificate by checking its integrity and the signature of the E2E Encryption (End-to-End Encryption): A system of communic....
If the certificate is deemed valid, the browser generates a unique session key and encrypts it using the server’s public key from the certificate. This encrypted session key is sent to the server. Both the browser and the server now possess the shared secret session key without exchanging it in plain text over the internet, ensuring secure communication.

The browser encrypts the data using the session key before transmitting it, and the server decrypts the received data using the same session key. This symmetric encryption allows for a fast and secure exchange of information, protecting it from eavesdropping and unauthorized access.

If the certificate cannot be verified, or it is expired, or it doesn’t match the website’s domain, the browser displays a warning to the user, indicating a potential security risk.

The handshake process, data encryption, and server identity verification are essential components of HTTPS port communication, contributing to a secure and trustworthy online experience.
