http vs https | How SSL (TLS) encryption works in networking ? (2023)
IT k Funde・12 minutes read
HTTP is a vulnerable protocol due to plain text data transfer, while HTTPS offers secure encrypted communication using SSL or TLS protocols, displaying a green padlock on browsers. HTTPS uses SSL certificates signed by authorities, with asymmetric encryption for public and private keys, and symmetric encryption for a single key, which is simpler but less secure.
Insights
- HTTP is a basic protocol for web communication that is vulnerable to hacking due to transmitting data in plain text, especially on public Wi-Fi.
- HTTPS, a more secure version of HTTP, encrypts data using SSL or TLS protocols, displaying a green padlock on browsers, ensuring secure communication by using asymmetric encryption with public and private keys, along with SSL certificates from certificate authorities.

Secure Communication: HTTP vs HTTPS Explained
- HTTP is a layer 7 protocol allowing communication between a client browser and a web server.
- HTTP sends and receives data in plain text, making it vulnerable to hacking, especially on public Wi-Fi.
- HTTPS, a more secure version, encrypts data using SSL or TLS protocols.
- HTTPS displays a green padlock on browsers, indicating secure communication.
- HTTPS encrypts and decrypts data, preventing unauthorized access to sensitive information.
- HTTPS uses SSL certificates signed by certificate authorities for secure communication.
- Asymmetric encryption in HTTPS involves a public key for encryption and a private key for decryption.
- Symmetric encryption in HTTPS uses a single key for both encryption and decryption, making it simpler but less secure.
