What is Https?

When connecting to HWP, Twitter, Facebook, Gmail or other secure websites, the green padlock logo on the side of your browser is caught in your eye. This tiny green padlock symbolizes secure connection, what is it, how it works, how it works?

There are many different technologies that provide our security on the Internet. HTTPS is a transport layer security system. HTTPS is an Internet protocol that allows web pages containing more than just one plain text to be connected to each other to be transmitted from the server to you for viewing on your computer or phone. The meaning of the word is ext hypertext transfer protocol ”. HTTPS, which is at the top of the seven different network layers, is an application layer. In other words, it has been decided in which form the data wiring of physical cable connections have already been made, the electrically communicated data particles are transmitted to the opposite side, handshake to meet in the network, which port will be used and data flow has started. HTTPS, the last layer on this flowing data, is secured in the previous layer, ie the sixth layer, making it impossible to read by external forces. HTTPS stands for HTTP Secure.


The system that connects with HTTPS and allows a small green lock to appear next to your browser works as follows: The owner of the server creates a security certificate for the server on this server and registers it with a verification company. In this registration process the SSL (secure socket layer) security certificate registrar (for example, Let’s Encrypt in our example) basically has a domain name called “hwp.com.tr and I have the IP address under the auspices of the server that this domain serves. it is a physical machine. Who does he say that to? Your browser; Internet browsers such as Google Chrome, Mozilla Firefox, Microsoft Edge, Opera, etc. rely on Let’s Encrypt and similar certificate providers, and accept the servers they witness to as the official addresses of these websites through the security certificates they sign. In this way, a trust mechanism is established.


People or organizations who interfere with the website that are running over HTTPS in a completely secure manner will only see that you have access to this website. So it is obvious that you go to https://hwp.com.tr address. However, the https://hwp.com.tr piltesti address you access at this point, the user names you use when logging in and the contents of the pages cannot be understood in any way.


The companies that provide certificates with different security ancillary services give these security certificates between 50 and 200 TL per year. Let’s Encrypt, which finances this business in different ways and does not charge the user, has zero costs as a voluntary initiative. Although it requires serious technical knowledge, it is relatively easy to use with the resources available on the Internet.
