HTTP vs. HTTPS: Securing Web Transactions

HTTP vs. HTTPS: Securing Web Transactions

What is HTTP?

HTTP (Hypertext Transfer Protocol) is the foundation of data transfer on the World Wide Web. It's the protocol that governs how web browsers and servers communicate with each other. When you visit a website, your browser sends an HTTP request to the web server, and the server sends back an HTTP response, containing the web page's data.

What is HTTPS?

HTTPS (Hypertext Transfer Protocol Secure) is a secure version of HTTP. It uses TLS/SSL (Transport Layer Security/Secure Sockets Layer) to encrypt the communication between your browser and the server. This encryption ensures that the data exchanged between your browser and the server is protected from eavesdropping and tampering.

How HTTPS Works:

1. Encryption Key Exchange: When you access a website with HTTPS, your browser initiates a secure connection. The server provides a digital certificate, which contains the public key for encryption.
2. Data Encryption: Your browser uses the public key to encrypt the data it sends to the server. The server uses its corresponding private key to decrypt the data.
3. Secure Communication: The encrypted data is transmitted over the internet. Even if someone intercepts the data, they won't be able to read it without the private key.

Why HTTPS is Important:

• Data Security: HTTPS protects sensitive information like login credentials, credit card details, and personal data from being intercepted and stolen.
• Website Integrity: HTTPS ensures that the data you receive from a website hasn't been tampered with. This helps prevent phishing attacks where malicious actors try to trick users into revealing sensitive information.
• Improved User Trust: Websites using HTTPS have a padlock icon in the browser's address bar, which indicates a secure connection. This builds trust with users and encourages them to share their information.

Differences Between HTTP and HTTPS:

Conclusion:

HTTPS is essential for securing online transactions and protecting user privacy. Always ensure that you are using HTTPS websites, especially when sharing sensitive information. Look for the padlock icon in the address bar and the "https://" prefix in the website's address.
