What is the difference between http and https
HTTP (Hypertext Transfer Protocol) is the foundation for transferring data on the web. It’s like a postman delivering letters.
HTTPS (Hypertext Transfer Protocol Secure) is the same postman but wearing a suit of armor. It adds an extra layer of security using encryption, making it harder for others to intercept and read the information being sent.
In short: HTTP is plain text, while HTTPS is encrypted.
Here’s a more detailed breakdown:
HTTP:
* Unencrypted: Data is transmitted in plain text, making it vulnerable to interception and eavesdropping.
* Port 80: Uses port 80 for communication.
* Less secure: Generally considered less secure due to the lack of encryption.
HTTPS:
* Encrypted: Uses Transport Layer Security (TLS) or Secure Sockets Layer (SSL) to encrypt data, making it difficult for unauthorized parties to access.
* Port 443: Uses port 443 for communication.
* More secure: Considered more secure due to the encryption layer, protecting sensitive information like passwords, credit card numbers, and personal data.
Key differences:
* Security: HTTPS is more secure than HTTP due to encryption.
* Port: HTTPS uses port 443, while HTTP uses port 80.
* URL: HTTPS URLs start with “https://,” while HTTP URLs start with “http://.”
* Browser indication: Browsers often display a padlock icon in the address bar to indicate a secure HTTPS connection
