This post will tell you the importance of https:// server and the difference between http:// and https:// server.
We will always suggest you to use HTTPS server instead of using HTTP server because of various number of reasons such as security, performance benefits and various SEO advantages. The data you are sending to the server will be more secured and also provides privacy all time so that no third party account access your personal information. So, here we will tell you how http:// and https:// server works. So read constantly, you need to know more about this.
What is HTTP?
HTTP stands for Hypertext Transfer Protocol. The World Wide Web(www) is all about communication between web clients and web servers.
- Clients are often browsers (Chrome, Edge, Safari), but they can be any type of program or device.
- Servers are most often computers in the cloud.
So the communication between client computers and web servers is done by Http Request and Http Response.
When you enter http:// in the address bar of your browser, it tells the browser to connect over HTTP. HTTP is use to transfer the data and information through connected or networked devices. HTTP uses TCP (Transmission Control Protocol) over port 80 by default to send and receive data packets over the web. Here, Http send data from client to the server using TCP and port 80. And the receiver receive the complete information or status.
Http does not encrypt and decrypt data which disrupts the security over data. And in that server, if you put some useful personal information, then hacker’s can steal your data and this may also hamper your privacy. HTTP server will also decrease the performance of you website.
So be careful, while entering you personal and important details on http server such as your credit card details, you email id and passwords, etc. Because may be hacker’s will maliciously steal you data, and this will create a problem to you because http server does not encrypt you data.
What is HTTPS?
HTTPS stands for Hypertext Transfer Protocol Secure, is the secure version of HTTP. It is the secure way to send data and information between client and server. It is secure communication between web server and web client only, no third-party server can steal your information. It increases security by encrypt your data.
When you enter https:// in the address bar of your browser, it tells the browser to connect over HTTPS. Generally sites are running https:// server, so even if you type http://, it will redirect you to https:// automatically.
HTTPS also uses TCP (Transmission Control Protocol) to send and receives data packets but over 443 port address within a connection which is encrypted by TLS(Transport Layer Security). Any website, especially those that require login credentials, should use HTTPS.
In modern web browsers, such as Chrome, websites that does not use https://, looks differently or will show “NOT SECURE” in the address bar. So, you can easily able to know which websites are secure and runs over HTTPS.
HTTPS uses an encryption protocol to encrypt communications. The protocol is called Transport Layer Security (TLS), although formerly it was known as Secure Sockets Layer (SSL). HTTPS uses SSL certificate to issued websites to be secured.
Difference Between HTTP & HTTPS:
| HTTP | HTTPS |
|---|---|
| It stands for Hypertext Transfer Protocol. | It stands for Hypertext Transfer Protocol Secure. |
| HTTP is less secure. | HTTPS is more secure and a secured version of HTTP. |
| HTTP uses port 80 by default | HTTPS was uses port 443 by default. |
| HTTP URLs begin with http://. | HTTPs URLs begin with https://. |
| HTTP does not use any certificate. | HTTPS uses SSL(Secured Socket Layers) certificate. |
| HTTP works in the application layer of OSI Model. | HTTPS works in the transport layer of OSI Model. |
| It helps to transfer text, audio, video, images from webpages. | It helps to transfer data securely via network. |
Hope this article helped you understand better about HTTP and HTTPS. Thank you!!!
