What is HTTPS?

Hello dear users, many of us know the importance of https, but I think it is worth repeating.

What is HTTPS and what does it provide?

HTTPS (Secure Hyper Text Transfer Protocol): We can briefly define it as a secure text transfer communication protocol. It is created by adding the SSL (Secure Socket Layer) protocol to the classic HTTP protocol. In other words, it means encrypting the communication that websites establish via texts.

Protocols are the rules that regulate how information is transferred between internet servers and users so that it cannot be read by others. You may have seen that in bank transactions or credit card transactions, HTTPS is written instead of http in the address bar. This is to ensure that your information does not fall into the hands of a third party during your transaction. There is no encryption in HTTP information exchanges. When you add the letter S next to it, this communication is now encrypted.

Differences with HTTP:

In case of HTTP, the URL starts with “HTTP://” and for HTTPS connection it is HTTPS://.

HTTP is insecure but HTTPS is secure.

HTTP port uses port 80 unlike HTTPS which uses 443 for communication.

In the case of HTTP, validating certificates is not required. Requires HTTPS SSL Digital Certificate.

There is no encryption in HTTP. In HTTPS, data is encrypted before sending and receiving.

Where to Use: It is used wherever you communicate with the browser. For example, it is used when sending an e-mail, typing a credit card password, registering to a site, etc.

How it Works in the Browser: The protocol uses verified and trusted server certificates when encrypting. When the user wants to access a page encrypted with https, the encryption certificate of the page must be recognized by the browser. If the page works with a certificate recognized by the browser, the browser considers this page safe. If the certificate is not recognized by the browser, the user is asked whether they trust the certificate.

Emergence: It is a protocol introduced by Netscape in 1994. It was first tried and developed in Netscape Navigator browsers.

Obtaining a Certificate: Certificates distributed with web browsers can be obtained for a certain annual fee.

Cost of SSL: Most SSL certificate providers offer these certificates for under $100 for one year. As Teknosos Bilişim Hizmetleri, we offer this service to you free of charge.
