HTTP solves the problem of how to request and receive files and web pages over the internet between a client (like a web browser) and a server. It defines a protocol for communication that allows users to ask for specific files or data from servers in a structured way using plain text commands such as "GET." Essentially, HTTP enables the transfer of hypertext documents and resources that make up the World Wide Web. However, HTTP by itself does not provide security for the data being transmitted—it sends information in plain text, which can be intercepted and read by attackers.
HTTPS, which stands for HTTP Secure, is an extension of HTTP that solves the security problem by encrypting the data exchanged between the client and the server. It ensures confidentiality, data integrity, and authentication by using encryption protocols such as SSL/TLS. This prevents anyone intercepting the data from reading or altering it, protecting privacy and securing sensitive information like passwords, credit card numbers, and personal data during transmission.
In summary:
- HTTP solves the basic problem of how to request and transmit resources on the web.
- HTTPS solves the problem of securing that data transmission against eavesdropping, tampering, and impersonation by encrypting the communication.
This combination allows the web to be functional and secure for users worldwide.
