What is http and https protocol? What’s different? Things to know to use the Internet more safely

Http, https is one of the basic hypertext transfer protocols on the Internet, between the user’s computer and the server. So what is the difference between http and https? How to use these protocols to access the Internet more securely? Read the article below to get the answer.

What is Http, what is https?

Http is the protocol through which the server and client communicate with each other.

Http stands for HyperText Transfer Protocol (hypertext transfer protocol). It is the most frequently used application protocol in the TCP/IP family of protocols (a group of foundational protocols for the internet).

Http works based on the Client (client) – Server (server) model . The user’s computers will act as the client (Client). After a certain user action, the clients will send a request to the server (Server) and wait for the answer from these servers.

Https is a secure version of http (short for Hyper Text Transfer Protocol Secure), the protocol through which data is sent between your browser and the website you’re connecting to.

Difference between http, https?

Characteristic	http	https
Operation model	The client-server model over the HTTP protocol.	Client-server model, adding SSL and TSL protocols (ensure that no one other than clients and servers can hack information and data out).
Encode	Information is not encrypted.	Information is encrypted, using SSL / TSL standard security technology , encrypted communication between Web server and browser.
Security level	Not encrypting information so hackers can easily steal information. Less security , information easily leaked, eavesdropped.	Supports the authentication of the identity (by logging into the account) of the website visited by the client through the security authentication check. Information security , safety with users.

Things to know when using http, https

When accessing electronic payment sites, users need to identify the protocol that the website is using .

In businesses or reputable electronic payment systems, the use of https protocol is almost one of the mandatory requirements for these businesses.

If not using the https interface, it is possible that the website is pretending to steal user information.

Usually, the link of websites that use the https protocol often comes with a small padlock-shaped icon . When you put the mouse pointer on this icon, the name of the authentication unit (CA) will appear on it.
