HTTP (Hypertext Transfer Protocol) and HTTPS (Hypertext Transfer Protocol Secure) are two protocols used for transmitting data over the internet.
In simple terms, HTTP is the foundation of communication between a web browser (client) and a web server. It defines how data is requested and transferred between the two. When you type a URL in your browser, such as “http://www.example.com,” the browser sends an HTTP request to the server to retrieve the webpage.
HTTPS, on the other hand, is a secure version of HTTP that adds an extra layer of encryption to the data transmission. It uses SSL/TLS (Secure Sockets Layer/Transport Layer Security) protocols to encrypt the communication between the browser and the server, ensuring that data exchanged cannot be intercepted or tampered with by malicious actors.
To understand the difference, imagine sending a letter through regular mail (HTTP) versus sending it in a sealed envelope through a secure courier service (HTTPS). The sealed envelope provides privacy and security for the contents of the letter, making it harder for anyone to tamper with or read the information inside.
HTTPS is essential for protecting sensitive data transmitted over the internet, such as passwords, credit card details, or personal information. It is commonly used for e-commerce websites, online banking, and any website that handles confidential user data.
When you visit a website with HTTPS, you’ll typically see a padlock icon in the browser’s address bar, indicating that the connection is secure. The URL will also begin with “https://” instead of “http://.”
It’s important to note that transitioning a website from HTTP to HTTPS requires obtaining an SSL/TLS certificate, configuring the server, and ensuring all elements on the website are secure. This process helps protect the privacy and security of users’ data.
In summary, HTTP is the protocol for transmitting data between a browser and a web server, while HTTPS adds encryption to ensure secure communication. HTTPS is used for transmitting sensitive data over the internet, providing privacy and protection against eavesdropping or tampering. It is denoted by a padlock icon in the browser’s address bar and “https://” in the URL.
