If you spend quite some time online, you must have noticed quite a few times that the search bar changes from HTTP to https or maybe vice-versa. Does that worry you a bit? Well, you actually don’t have to! A lot of times, people get worried whether their information is safe and secure in such instances. However, we are just about to burst the bubble!
In this post, let us tell you about the difference’s’ between HTTP and HTTPS! And, trust us, it is not that bad!
Fits of all, let us touch the basics of the both.
What is HTTP?
HTTP stands for HyperText Transfer Protocol. It is mostly a thing of the past today. In the earlier times, the network administrators had to face the major challenge of securing their information online. They also wondered how to share it properly on the internet, without facing any privacy issues.
That is why led to the development of HTTP. It was a procedure that the various administrators mutually agreed to use to exchange information. However, the major problem again was that once it became too common and everyone knew about it, getting the information leaked was no big deal! That is when people started worrying about the security and privacy of their information online.
Then came the system of encrypting the data online. The protection depends on an SSL certificate that is used to protect and secure your data online.
So, do you know what encryption means? Well, it’s kind of an “NDA” that you sign! It is basically a code that the sender and receiver of a message agree upon. This helps them translate their personal documents into a number of character strings, which will be unreadable by any other entity.
Does that calm you down a bit? Relief, isn’t it?
That brings us to the concept of HTTPS.
What is HTTPS?
This process of encrypting and protecting your information online and sharing it with others is what we call HTTPS. It stands for Hyper Text Transfer Protocol Secure. When you have the HTTPS security with you, you do not have to worry a bit about anyone getting a hold of your document in the middle of the exchange. Even if a third party tries to open your document, they understand nothing of it! Without the “code”, no one can make out what exactly is in the document!
Now, that we have a basic idea of what exactly are HTTP and HTTPS, shall we move on and see what the major points of difference between the two are?
Difference Between HTTP and HTTPS
So, now we come to the main point in the discussion. The difference between the two. The fundamental difference lies in the fact that while HTTP is unsecured, HTTPS is a much secured.
Let us look at some of the other key differences between the two.
- HTTP is operated on the application layer while HTTPS is operated on the transport layer.
- There is no encryption on HTTP while HTTP uses encryption of data.
- There is no need for a certificate in HTTP while a certificate is mandatory in case of HTTPS.
- HTTPS uses port number 443 for communication. On the other hand, HTTP uses port number 80.
- HTTP is prone to insecure attacks. This is not the case in HTTPS.
Now, let us have a brief look at how each of these entities works.
How Does HTTP Work?
The working of HTTP depends on the request and response cycle. In such instances, the client usually asks for a web page. Whenever a client is browsing the website, he first sends a message to the server. This message is what we call the HTTP message. The server crafts a response and reverts to the same. It consists of mainly two things:
The start line
This consists of the method, URI and the HTTP version.
This section consists of the informational rules related to the host, accept and accept language.
How Does HTTPS Work?
In order to secure a website, you have to purchase an SSL certificate. This is basically an identification card for your network. This encrypts all the data that you send online.
Under this process, when a client is looking for any data from the server, the SSL certificate is required to verify the identity of the website.
This helps you to better be safe and secured while using the internet for online transactions of personal information or money.
Where Can These Two be Used?
In all those pages where you do not need a secured access, you can go on with HTTP These include internet forums and educational or news sites.
Wherever you require a transaction of vital information, you must go for HTTPS. These include banking networks, payment gateways and shopping websites etc.
Thus, we see that HTTPS is vital for securing and encrypting your private data. You must go to HTTP when you feel that your exchange of data is not that precarious!
Now, that you know all about it, we hope you are in a much better situation to understand the technicalities associated with the same. Then, why keep the information to yourself? Share this article to let your friends know!
