Simple Difference Between http and https

Simple Difference between HTTP and HTTPS || cyberaditya

 Hello Friends sorry for the delay in post because every thing that I am trying now , doesn't give any positive results to me So please pray for me :P

In this post we will learn the simple difference between HTTP and HTTPS. I am not going to give a deep info about it because it may become boring to read for you, We will learn just the simple difference between two of them 

First of all What is HTTP ???

HTTP is Hyper Text Transport Protocol and is transmitted over the wire via PORT 80(TCP). You normally use HTTP when you are browsing the web, its not secure, so someone can eavesdrop on the conversation between your computer and the web server

Second What is HTTPS ??

HTTPS (Hypertext Transfer Protocol over Secure Socket Layer, or HTTP over SSL)

is a Web protocol developed by Netscape and built into its browser that encrypts and decrypts user page requests as well as the pages that are returned by the Web server. HTTPS is really just the use of Netscape's Secure Socket Layer (SSL) as a sublayer under its regular HTTP application layering. (HTTPS uses port 443 instead of HTTP port 80 in its interactions with the lower layer, TCP/IP.) SSL uses a 40-bit key size for the RC4 stream encryption algorithm,new-age browsers use 128-bit key size which is more secure than the former, it is considered an adequate degree of encryption for commercial exchange.HTTPS is normally used in login pages, shopping/commercial sites. Nowadays facebook is also working on HTTPS

Simple Conclusion !

As also cleared from the above picture we may conclude that :-
http is hyper text transfer protocol which is responsible for transmitting and receiving information across the Internet where as https is secure http, which is used exchanging confidential information with a server, which needs to be secured in order to prevent unauthorized access.

So when you are attempting to do some secure transaction over internet use https.
