What is the difference between HTTP and HTTPS?

You must have seen HTTP and HTTPS in the address bar of the web browser.At some times in your mind, the question must have been, what are they, how do they work and what is the difference between HTTP and HTTPS.

In this post we have tried to give complete information about HTTP and HTTPS and hope that by reading this, you will get the answers to all your questions related to HTTP and HTTPS.

What is http?

Full form of http is hypertext transfer protocol at www if we have created a set of rules for transferring files to text, video or graphic images, sound, other multimedia files. Whenever a users opens a web browser, users start using HTTP indirectly. HTTP is an application protocol that acts on top of the TCP / IP suite of protocols (the foundation protocol for the Internet). The new version of HTTP is HTTP / 2, which was released in May 2015. This is an alternative to the older, HTTP 1.1, but it is popular.

How does http work?

Web server machines have an HTTP daemon that is designed to request a program HTTP and control them when received. A web browser is an HTTP client, requesting for server machines. When a user requests a web file by typing an open name or using a hypertext link, the browser creates an HTTP request, sending it to the address of the Internet Protocol address from which the request originates from the server http domain. Resends file with.

With an example, we understand that a user goes to Google.com, the user writes that address and the computer sends a GET request to the server hosting that address. GET request is sent using HTTP then it is searching on Google.com server that user is searching HTML code while it is being requested, then they reduce the use of TCP / IP and users Sends information in small packets of binary number to zero and the information is sent through physical wires, fiber optic cables or wireless networks.

What is https? 

The full form of https is hypertext transfer protocol is secure which is the primary protocol used to send data between web browser and website like http. With HTTPS we can send data with security. To increase the security of data transfer to https, the data is encrypted and sent. This is most important then.

When sending sensitive data to users, such as bank accounts, email services, or health insurance providers. All websites or specific websites that require login credentials should use HTTPS. In new web browsers like Chrome, websites using HTTPS and those using https are different. To see if the webpage is secure or not, you should see the green padlock in the URL.

How does HTTPS work? 

HTTPS uses the encryption protocol in which data is sent in an encrypted format. The protocol was first known as (SSL) Secure Socket Layer and then later called (TCL) Transfer Security Layer. This protocol uses the secret key The data is kept secure by using two different keys to encrypt the communication between the two parties keeping the security system in mind.

In which the first private key is used by the owner of the website, this key is a web server and its use is used to decrypt the information encrypted by the public key. The second key is the public key that is known to everyone who talks to the server which is secure. Information encrypted by the public key can only decrypted by the private key.

Which is better https or VPN?

Both HTTPS and VPN encrypt your information - but a VPN encrypts it more. HTTPS encrypts what is sent to a server and back via a browser only and only when it is enabled on the sites you visit. A VPN will encrypt everything (as long as you keep it running there will be a lot of communication going on!).
