While you search anything in the browser URL you see only HTTP:// or HTTPS:// which defines a set of rules. These protocols help to exchange the information from Client to server or Server to Client. but what is the difference between HTTP and HTTPS protocols actually?
This article will cover most of the points of difference between HTTP and HTTPS Protocol. So let’s first start from What is HTTP and HTTPS following with more details of both.
What is HTTP?
HTTP stands for Hypertext Transfer Protocol which is the foundation of the World Wide Web. HTTP by default use port 80. It is also called an application-level protocol for distributed, collaborative, and hypermedia information systems. This protocol allows clients to communicate data on the World Wide Web.
This is the generic and stateless protocol as well which also can be used for other purposes using an extension of its methods, headers, and error codes. Additionally, clients send the request from the browser to the web server in the form of web pages and images. When a server receives this request, the connection will be disconnected between Client and Server.
Advantages of the HTTP protocol
- HTTP protocol uses the low CPU and memory due to the fewer simultaneous connections.
- Though this is the simple messaging protocol, it has the ability to search the database in a single request which allows the protocol to implement SQL searches and get results traditionally formatted in an HTML document.
- It has lower network congestion as there are fewer TCP connections.
What is HTTPS?
HTTPS stands for Hypertext Transfer Protocol Secure and by using this protocol encrypted information for instance; credit card information, bank accounts, health insurance details, and user id or passwords can be transferred securely on the internet.
This protocol by default uses port 443. Https protocol uses the SSL (Secure Socket Layer) or TLS (Transport Layer Security) which helps to maintain the privacy and integrity of data on websites. In addition, the HTTPS protocol rapidly became the primary protocol for sending and receiving information on the internet.
In other words, we can say Https protocol protects the communication which happens between client and servers. It can not be tampered with or intercepted by hackers.
Advantages of the HTTPS protocol
- This protocol provides data integrity as it provides data encryption over the internet, no hacker can read or modify the data.
- Secure communication makes connections between client and browser as an encrypted link.
- It provides reliability as the green padlock shows in the website URL. When a user comes on the website feels that the website is secure and he can make the transaction.
- It also helps in website SEO activity. A website with SSL or contains an HTTPS certificate will have a higher rank than the website that does not have it.
- Https protocol will be the future of all websites by promising internet safety and security.
What is the difference between HTTP and HTTPS protocol?
HTTP |
HTTPS |
| It is a Hypertext transfer protocol. | Hypertext transfer protocol secure. |
| It uses the default port# 80 | It uses the default port# 443. |
| The website URL will be like http://www.example.com | The website URL will be like https://www.example.com |
| The HTTP protocol is considered an unsecured protocol and hackers are easily able to hack information. | The HTTPS protocol is considered the secure protocol as it encrypts the information over the internet connection and hackers are not able to hack the information easily. |
| This protocol works on an application-level layer. | And this protocol works on Transport Layer. |
| It does not help the websites in SEO ranking. | It helps in SEO ranking. |
| Performance-wise it is fast. | It is slow as it encrypts the data in request and response. |
| This protocol transfers information in plain text format. | This protocol transfers information in the encrypted text or ciphertext. |
What is an SSL Certificate means?
An SSL (Secure Socket Layer) Certificate is a digital certificate installed on the Web Server in the form of a Cryptography key. It activates the padlock (HTTPS://) and allows secure connection on Web Browser to Web Server.
SSL certificates bind a domain name, server, or hostname together. And also company identity, and location.
What is Transport Layer Security (TLS)?
TLS or Transport Layer Security is a cryptographic protocol that provides security over the network for the end to end communications. It also provides authentication, privacy, and data integrity. Moreover, It is derived from the SSL security protocol.
