What is the HTTP protocol? What is the difference between HTTP and HTTPS?

HTTP Protocol (Hypertext Transfer Protocol) is the main protocol for data transmission on the internet. It is used for interaction between web browsers and web servers, allowing the retrieval and sending of data such as HTML pages, images, styles, javascript, etc.

HTTP operates on a client-server model, where the web browser acts as the client that sends requests, and the web server processes these requests and sends responses. The protocol is text-based, meaning that data is transmitted in the form of text messages.

HTTPS (Hypertext Transfer Protocol Secure) is an extension of the HTTP protocol using a security layer (SSL or TLS) to provide an encrypted connection between the client and the server. The main difference between HTTP and HTTPS is that HTTPS ensures data security by encrypting the transmission of information between the client and the server.

Data Encryption

In the case of HTTPS, the data transmitted between the client and the server is encrypted, making it more secure from eavesdropping by third parties.

Server Identification

HTTPS allows the server to confirm its identity using a digital certificate. This helps to avoid the possibility of man-in-the-middle attacks.

Connection Port

HTTP uses port 80 for connections, while HTTPS uses port 443. This allows servers to distinguish between connection types.

Using HTTPS is recommended for all websites, especially those that transmit confidential or personal data.
