How does HTTP differ from HTTPS?

HTTP (HyperText Transfer Protocol) is a data transfer protocol on the internet that operates without encryption. HTTPS (HTTP Secure) is an extension of HTTP that uses SSL/TLS to encrypt data between the client and the server.

Main differences:

• Security: HTTPS protects data from interception and forgery, HTTP does not.
• Port: HTTP typically uses port 80, HTTPS uses port 443.
• Performance: HTTPS requires additional resources for encryption, but modern optimizations minimize delays.

Example: when entering a password on a website via HTTP, the data can be intercepted, whereas via HTTPS, it is protected.
