How to know the difference between http and https


What is the difference between http and https? 
By Ifediogor Uche

A lot of persons have asked this question "what's the difference between http and https?. Still confused or living in the dark, worry not. In this article I am going to explain it to you in the language you will understand ,so sit tight and relax. Also as you delve into this make sure you read this to the end to get every necessary information without living any stone unturned.

Consequently, some of you might know about this difference, yet it is worth sharing for some, that are definitely not.

Protect yourself from cyber theft

However ,with the rate at which cyber theft is increasing around the world and in Nigeria, it's becoming so alarming that one needs to be careful and well informed. There is a saying that if you are not informed you are deformed. In otherwords, what you don't know is actually bigger than you because no man rises above his level of knowledge and understanding .

Suffice to say, data is not the only target when it comes to cybercrimes.Lets not also be ignorant of the fact that some core systems also  such as industrial controls are being hacked in a dangerous trend to disrupt and destroy,   and also steal money. Cyber theft is really on the rise more companies including individuals are losing money because of this act.

In the midst of intellectual ferments, let's always do our best and in the same vein due diligence to take cognicance before we register and supply vital information on any public sites.

Now, that we have laid this foundation, let's hitch hike to the topic of discuss. Take a ride with me as I divulge and explain to you the difference between http and https.


The primary difference between http:// and https:// is all about keeping you secure.

In terms of security, HTTP is  fine when surfing the web. This only becomes a problem when you're registering or submitting sensitive data into form fields on a website. If you're entering sensitive data into an HTTP web page, that data is transmitted in cleartext and can be read by anyone and those customers data is insecure.

One of the main benefits of HTTPS is that it adds security and trust.

So, one of the  differences between HTTP vs HTTPS is simply the presence of a SSL certificate. HTTP doesn't have SSL and HTTPS has SSL, which encrypts your information so your connections are secured. HTTPS also has TLS (Transport Layer Security) protocol that HTTP lacks. HTTPS is more secure than HTTP.

HTTP and HTTPS are both protocols. A protocol is basically a way of communication between the web server and the web browser. Starting from the simplest difference between these two terms - HTTP stands for Hypertext transfer protocol and HTTPS stands for Hypertext transfer protocol secure.

It’s not just the ‘S’, these differ in more aspects and one of them is their layer of working. While HTTP is an application layer protocol, HTTPS is a server level protocol. For HTTP to become HTTPS you need an SSL certificate installed from a trusted certification authority.

HTTP stands for Hyper Text Transfer Protocol.
The S (big surprise) stands for "Secure". If you visit a Website or web page, and look at the address in the web browser, it is likely begin with the following: http:///.

This means that the website is talking to your browser using the regular unsecured language. In other words, it is possible for someone to "eavesdrop" on your computer's conversation with the Website. If you fill out a form on the website, someone might see the information you send to that site.

This is why you never ever enter your credit card number in an
Http website! But if the web address begins with https://, that means your computer is talking to the website in a
Secure code that no one can eavesdrop on.


Presently, you comprehend why this is so significant, isn't that so?

If a website ever asks you to enter your Credit/Debit card
Information, you should automatically look to see if the web
address begins with https://.

If it doesn't, you should NEVER enter sensitive Information such as a credit/debit card number. Run for your dear life.

Web browsers such as Internet Explorer, Firefox and Chrome also display a padlock icon in the address bar to visually indicate that a HTTPS connection is in effect.


While checking the name of any website, first look for the domain extension (.com or .org, .co, .in, .net etc). The name just before this is the domain name of the website. E.g, in the above example, http://amazon.diwali-festivals.com, the word before .com is "diwali-festivals" (and NOT "amazon"). So, this webpage does not belong to amazon.com but belongs to "diwali-festivals.com", which we all haven't heard of before.
You can similarly check for bank frauds.

Wisdom demands that before your ebanking logins, make sure that the name just before ".com" is the name of your bank. "Something.Uba.com" belongs to Ecobank ; but, uba.some1else.com belongs to "some1else.

Port:
Another difference between these two is that they both use different ports,

HTTP - Port 80

HTTPS - Port 443


A port is a physical docking point using which an external device can be connected to the computer. It can also be programmatic docking point through which information flows from a program to the computer or over the Internet.

The port 80 doesn’t have any algorithm to encrypt data which  comes in out across it. Http is vulnerable per se

The protocol called HTTPS which can be used to send data in an encrypted manner . So they used separate port 443 which was bind by hashing (MD5 ..etc) algorithm like SSH(port 22).

So any data moving in port 443 , it will encrypt the data according to the hashing algorithm which was bind on the 443 port.


I believe you have hopefully learned something new, even though some of you may not be the tech savvy guys ,there is always something to learn when an information is been dished out. Therefore, please share and educate others. Stay safe as more scammers and cyber criminals are on the loose these days!. Don't fall a victim, trade with caution .
