HTTPS (HyperText Transfer Protocol Secure) is an extension of HTTP, designed to provide secure communication over a computer network, most commonly the Internet. It utilizes encryption protocols such as SSL (Secure Sockets Layer) or TLS (Transport Layer Security) to secure data transferred between a user’s browser and a web server.

How HTTPS Works

When a user connects to a website via HTTPS, the communication between the browser and the server is encrypted to prevent interception by unauthorized parties. The process involves:

1. Handshake: The browser and server establish a secure connection by agreeing on encryption methods and exchanging encryption keys.
2. Authentication: The server presents a digital certificate, issued by a trusted Certificate Authority (CA), to prove its identity.
3. Data Encryption: All data sent between the browser and the server is encrypted, ensuring confidentiality and integrity.

Benefits of HTTPS

• Security: Protects against eavesdropping, man-in-the-middle attacks, and tampering.
• Privacy: Ensures that sensitive information like passwords and credit card numbers remain confidential.
• Trust: Displays a padlock icon in browsers, signaling to users that the website is secure.
• SEO: Many search engines favor HTTPS websites, improving search rankings.

Why Use HTTPS Everywhere?

With increasing threats to online security, it is recommended that all websites adopt HTTPS to protect user data and enhance trustworthiness. Modern browsers warn users when visiting non-secure HTTP sites, further emphasizing the importance of HTTPS.
