HTTP (HyperText Transfer Protocol) is a protocol for transferring data over the web, but it is not encrypted. Data transmitted via HTTP is vulnerable to interception by malicious parties.
HTTPS (HyperText Transfer Protocol Secure), on the other hand, is the secure version of HTTP. It encrypts the data using SSL/TLS (Secure Socket Layer/Transport Layer Security), ensuring that communications between the browser and server are encrypted and protected from man-in-the-middle attacks.
