What is the difference between http and https?

Some of you may be aware of this difference, but it is worth sharing for many that are not.

The main difference between http:// and https:// is all about keeping you secure. HTTP stands for Hyper Text Transfer Protocol.

Quick history of HTTP

Here is the fact of HTTP:



The Term HTTP is originated by .
HTTP connections uses a port 80 by default.
HTTP URLs begin with “http://”.
The first version of HTTP was introduced in 1991 that is HTTP V0.9.
HTTP V1.0 is specified in RFC 1945 that officially introduced and recognized in 1996.
HTTP V1.1 is specified in RFC 2616, and was released in January 1997.
HTTP V2.0 is specified in RFC 7540 and was published in May 2015
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://.


Here is the fact of HTTP:

HTTPS uses a port 443 by default to transfer the information.
HTTPS URLs begin with “https://”.
The HTTPS is first used in HTTPS V1.1 and defined in RFC 2616.

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. Now, you understand why this is so important, right? 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. PLS PASS IT ON (You may save someone a lot of grief). 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.

Eg, 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. Before your ebanking logins, make sure that the name just before ".com" is the name of your bank.

"Something.icicibank.com" belongs to icici; but, icicibank.some1else.com belongs to "some1els.
