HTTPS is the secure version of HTTP that uses encryption and authentication to protect data transmission.1. Definition and protocol: - HTTP (Hypertext Transfer Protocol): HTTP is the basic protocol for transferring data on the web. It enables the exchange of information between web browsers and web servers. - HTTPS (Hypertext Transfer Protocol Secure): HTTPS is the secure version of HTTP. It uses an additional layer of encryption to protect the data being transmitted. 2. Security and encryption: - HTTP: Transmits data in clear text, which means the data can be easily intercepted and read during transmission. It does not provide security or confidentiality. - HTTPS: Uses SSL/TLS (Secure Sockets Layer/Transport Layer Security) to encrypt data transmission. This protects the data from interception and tampering and ensures that communication between the user and the website remains confidential. 3. Authentication: - HTTP: Does not provide authentication, which means there is no guarantee that communication is actually going to the intended server. - HTTPS: Integrates an authentication layer provided by digital certificates. These certificates confirm the identity of the website and prevent users from being redirected to fake websites. 4. Data integrity: - HTTP: Since there is no encryption or authentication, the data can be changed or tampered with during transmission without the user or the server noticing. - HTTPS: HTTPS encryption and authentication ensures that the transmitted data cannot be altered during transmission, thus guaranteeing data integrity. 5. URL and Visible Differences: - HTTP: URLs start with "http://". When you access a website via HTTP, "http://" is displayed in the browser's address bar. - HTTPS: URLs start with "https://". In addition, modern browsers often display a lock symbol in the address bar to indicate that the connection is secure. 6. Application and distribution: - HTTP: Used widely in the past, but due to the lack of security measures, it is less suitable for data exchange, especially for sensitive information. - HTTPS: Is preferred today, especially for websites that transmit sensitive information such as passwords, credit card details or personal data. The use of HTTPS is rewarded by search engines such as Google and is a standard for secure communication on the web. Summary: HTTP and HTTPS are protocols for transmitting data on the web, but HTTPS provides additional security through encryption and authentication. HTTPS protects data from eavesdropping and tampering, ensures the identity of the website, and ensures data integrity, while HTTP does not provide these security features.
