What is HTTP & HTTP Protocol?

HTTP stands for hypertext transfer protocol.

Communication is done by this protocol in www (World Wide Web). This protocol determines how information like messages, videos and other files are transmitted, and how web servers and browsers act in response to different commands.

For example, when you search about a keyword or enter a URL in your browser, this actually send an HTTP command to the web servers and request it to fetch data related to keyword or URL that you entered in browser search bar, then web server transmit the requested web page on browser.

The other main standard that controls World Wide Web working is HTML, which is responsible for the format and appearance of web pages.

What is HTTPS?

HTTPS stands for hypertext transfer protocol secure, it’s a secure version of HTTP, which is primarily used to transmit data from web server to website. HTTPS is encrypted in order to increase security of data transfer and it’s very valuable when users transmit sensitive information, such as logging into any account, bank account, email service and insurance provider.

Generally every website, but especially those that require login information, should use HTTPS. Sometimes when you search, in modern web browsers such as chrome, websites don’t use HTTPS. These websites are marked differently than those that have green padlock in the URL bar to show that website is secure.

Why HTTPS is important? Why you should care about it?

HTTPS protects websites broadcasts information so that no one can easily view it by interfering on the network. When information is transmitted on simple HTTP, it broken into small data packets that can easily hacked using free software. In fact, all types’ communications over HTTP are unsecure due to plain text, such as public WI-FI connections, that are highly accessible to everyone.  The most benefit of HTTPS is that data is encrypted, no matter if the data packets are sniffed because they will show as nonsensical characters at output.

Now see if there is no HTTPS on your website then what type of disadvantages you can face. In a website without HTTPS, it may be possible for internet service provider or any other intermediate person to inject information into your webpages without your approval. The internet service provider can depicts ads on webpages and earn revenue from them. It is obvious, that profit of advertisement will not be shared with original owner of website. HTTPS removes the ability of unmoderated of third parties to inject their data into website content.

What is difference between HTTP&HTTPS?

Technically, HTTP and HTTPS use same protocol but HTTPS just have a extension of TLS/SSL encryption over HTTP protocol. Its mean HTTPS just giving a cover to data packets so it cannot be steal by a third party. HTTPS only sure, by using TLS/SSL transmission certificate, that particular provider is original.

When a user connect to website page, the webpage will send information over its SSL certificate which contains the public key, which is necessary to start the secure session. The two computers, the user and the server, then go through a process called an SSL/TLS handshake, which is a repeatedly process to establish a secure connection.  

How a website can use HTTPS?

Many hosting provider platforms provide SSL/TLS certificate for fee and some also charges a fee, like godaddy charge for SSL certificate. Once you have a dedicated IP address, purchase your SSL certificate. This acts as a form of identification for your website.

The SSL certificate is simply a string of numbers and letters that you install on your server. When people visit your site through the HTTPS address, the password is checked, verifying that your website is what it says.

The certificate is used to encrypt all data that flows to and from the server where the certificate is installed. You can learn about how to enable HTTPS on your server to be more secure.
