FNDifference between http:// and https://
Last Updated : 16 Jan, 2026
When browsing the internet, you often see website URLs starting with either http:// or https://. These prefixes indicate how data is transferred between your browser and the website’s server. While both HTTP and HTTPS are communication protocols, the key difference lies in security.
http:// and https://
What is HTTP?
HTTP (HyperText Transfer Protocol) is an application-layer protocol used for transferring data over the web. It was introduced by Tim Berners-Lee to enable communication between web browsers and web servers. HTTP defines a set of rules that allow clients (browsers) to request resources such as web pages, images, or videos from servers.

Key Points about HTTPKey:
Uses plain text for data transmission
Does not provide encryption or authentication
Vulnerable to data interception and modification
Default port number: 80
Note: HTTP does not encrypt data, sensitive information such as passwords or payment details can be easily compromised.
How HTTP Works
The client sends an HTTP request (e.g., GET or POST) to the server.
The server processes the request.
The server sends an HTTP response containing: Status code (e.g., 200, 404), Headers and Response body (data or error message).
What is HTTPS?
HTTPS stands for Hyper Text Transfer Protocol Secure. HTTP Secure (HTTPS), could be a combination of the Hypertext Transfer Protocol with the SSL/TLS convention to supply encrypted communication and secure distinguishing proof of an arranged web server. HTTPS is more secure than HTTP because HTTPS is certified by the SSL(Secure Socket Layer). Whatever website you are visiting on the internet, if its URL is HTTP, then that website is not secure.

Why HTTPS is Secure
Data is encrypted, preventing eavesdropping
Server identity is verified using digital certificates
Protects against man-in-the-middle attacks
Modern browsers clearly mark HTTPS websites as secure, and many features work only over HTTPS.
How HTTPS Works
The client initiates a secure connection.
The server presents its SSL/TLS certificate.
The client verifies the certificate with a trusted authority.
An encrypted session is established.
All HTTP data is transferred securely inside this encrypted channel.HIDGFGFGISHVUHBDFUGBHUDGFHIHDIVFHGIUDHFIDHUIVHDIUHVUDHVUIHDIUGHIUHFGIUHFIGHOIDSJHFGOI
