What protocol is used for sending encrypted information to protect data?

• A. HTTP
• B. FTP
• C. SSH
• D. HTTPS

Answer: (D)

The correct option, HTTPS, stands for Hypertext Transfer Protocol Secure. It is an extension of the standard HTTP protocol and is specifically designed to provide a secure communication channel over the internet. By incorporating SSL/TLS (Secure Socket Layer/Transport Layer Security), HTTPS encrypts the data transmitted between the user's web browser and the web server. This encryption ensures that sensitive information such as passwords, credit card numbers, and personal data remain confidential and are safeguarded from eavesdroppers or attackers during transmission. Using HTTPS is prevalent for any website that handles sensitive information, enhancing both the privacy and integrity of the data. In contrast, HTTP transmits data in plaintext, making it vulnerable to interception and tampering, which compromises security. Other protocols like FTP (File Transfer Protocol) are designed primarily for transferring files without embedded security features and SSH (Secure Shell) focuses on secure access and management of network services. Thus, HTTPS is the appropriate choice when it comes to encrypting data for secure online communication.
