Difference Between HTTP and HTTPS
HTTPS is HTTP with encryption. The only difference between the two protocols is that HTTPS uses TLS (SSL) to encrypt normal HTTP requests and responses. As a result, HTTPS is far more secure than HTTP. A website that uses HTTP has http:// in its URL, while a website that uses HTTPS has https://. Some difference of http and https;
Difference Between HTTP and HTTPS
- In HTTP, URL begins with "http://" whereas URL starts with "https://"
- HTTP uses port number 80 for communication and HTTPS uses 443
- HTTP is considered to be unsecure and HTTPS is secure
- HTTP Works at Application Layer and HTTPS works at Transport Layer
- In HTTP, Encryption is absent and Encryption is present in HTTPS as discussed above
- HTTP does not require any certificates and HTTPS needs SSL Certificates
Difference Between HTTP and HTTPS
| Parameter | HTTP | HTTPS |
|---|---|---|
| Full Form | Http stand for Hyper Text Transfer Protocol | Https stand for Hyper Text Transfer Protocol Secure. |
| Protocol | It is hypertext transfer protocol. | It is hypertext transfer protocol with secure. |
| Security | It is less secure as the data can be vulnerable to hackers. | It is designed to prevent hackers from accessing critical information. It is secure against such attacks. |
| Port | It uses port 80 by default | It was use port 443 by default. |
| Starts with | HTTP URLs begin with http:// | HTTPs URLs begin with https:// |
| Used for | It's a good fit for websites designed for information consumption like blogs. | If the website needs to collect the private information such as credit card number, then it is a more secure protocol. |
| Scrambling | HTTP does not scramble the data to be transmitted. That's why there is a higher chance that transmitted information is available to hackers. | HTTPS scrambles the data before transmission. At the receiver end, it descrambles to recover the original data. Therefore, the transmitted information is secure which can't be hacked. |
| Protocol | It operates at TCP/IP level. | HTTPS does not have any separate protocol. It operates using HTTP but uses encrypted TLS/SSL connection. |
| Domain Name Validation | HTTP website do not need SSL. | HTTPS requires SSL certificate. |
| Data encryption | HTTP website doesn't use encryption. | HTTPS websites use data encryption. |
| Search Ranking | HTTP does not improve search rankings. | HTTPS helps to improve search ranking. |
| Speed | Fast | Slower than HTTP |
| Vulnerability | Vulnerable to hackers | It Is highly secure as the data is encrypted before it is seen across a network. |
Limitations of HTTP
- There is no privacy as anyone can see content
- Data integrity is a big issue as someone can alter the content. That's why HTTP protocol is an insecure method as no encryption methods are used.
- Not clear who you are talking about. Anyone who intercepts the request can get the username and password.
Limitations of HTTPS
- HTTPS protocol can't stop stealing confidential information from the pages cached on the browser
- SSL data can be encrypted only during transmission on the network. So it can't clear the text in the browser memory
- HTTPS can increase computational overhead as well as network overhead of the organization.
