HTTPS (HyperText Transfer Protocol Secure) is the foundation of secure internet communication. It encrypts data exchanged between browsers and servers, ensuring privacy and data integrity. Here's a breakdown of its key components:

🔒 What is HTTPS?

HTTPS combines HTTP with SSL/TLS encryption.

  • HTTP: Standard protocol for data transfer
  • SSL/TLS: Secure Socket Layer/Transport Layer Security protocol
  • Encryption: Data is scrambled during transmission

🔄 How Does HTTPS Work?

  1. Handshake Process:

    • Browser requests connection to a secure site (e.g., https://example.com)
    • Server responds with its SSL certificate (containing public key)
    • Keys are exchanged to establish a secure channel

  2. Data Encryption:

    • All data is encrypted using symmetric keys
    • Encryption icon:

📌 Why Use HTTPS?

  • Protects sensitive information (credit cards, passwords)
  • Prevents man-in-the-middle attacks
  • Builds trust with users via padlock icon
