DIRRRENCE BETWEEN HTTP OR HTPPS

 HTTP (Hypertext Transfer Protocol) and HTTPS (Hypertext Transfer Protocol Secure) are both protocols used for transmitting data over the internet, but they differ primarily in terms of security:


1. **Security:**

   - **HTTP:** HTTP is not secure by default. Data transferred over HTTP is in plain text, which means it can be intercepted and read by malicious parties, making it vulnerable to eavesdropping and data theft. It does not provide encryption or data integrity.


   - **HTTPS:** HTTPS is designed to be secure. It uses encryption to protect the data transmitted between a user's web browser and the web server. This encryption is typically implemented using SSL/TLS (Secure Sockets Layer/Transport Layer Security) protocols. As a result, data transmitted over HTTPS is encrypted, making it difficult for unauthorized parties to intercept or decipher.


2. **Data Integrity:**

   - **HTTP:** HTTP does not guarantee data integrity. Since data is transmitted in plain text, it can be altered during transmission without detection.


   - **HTTPS:** HTTPS ensures data integrity. The encryption process includes mechanisms to detect and prevent tampering with the data. If data is modified during transit, the receiving end will recognize the alteration and reject the compromised data.


3. **Authentication:**

   - **HTTP:** HTTP does not provide strong authentication mechanisms. This means that it's easier for malicious actors to impersonate a website or intercept data by posing as a legitimate server.


   - **HTTPS:** HTTPS incorporates a system of certificates and public key infrastructure (PKI) to authenticate the identity of the web server. This helps users ensure they are connecting to a legitimate and trusted website, reducing the risk of phishing and man-in-the-middle attacks.


4. **URL Prefix:**

   - **HTTP:** URLs using HTTP typically start with "http://."


   - **HTTPS:** URLs using HTTPS start with "https://."


5. **Port Number:**

   - **HTTP:** The default port for HTTP is 80.


   - **HTTPS:** The default port for HTTPS is 443.


In summary, the primary difference between HTTP and HTTPS is security. HTTPS is designed to provide a secure and encrypted connection between a user's browser and a web server, protecting data from eavesdropping, tampering, and impersonation. It is widely used for secure transactions, such as online shopping, online banking, and sensitive data transfers, to ensure the privacy and security of user data.
