How does an SSL certificate work?

An SSL certificate primarily functions to encrypt the data transmitted between a web server and a browser. This encryption ensures that any information exchanged, such as login credentials, personal details, and financial data, remains confidential and secure from potential eavesdroppers or cyber attackers. By establishing a secure and encrypted connection, SSL certificates protect against data breaches, man-in-the-middle attacks, and other cybersecurity threats, fostering trust between users and websites.

In the context of web security, the importance of this encryption cannot be overlooked. When a browser communicates with a server over HTTPS (the secure version of HTTP), the SSL certificate protects the integrity and privacy of the data during transit. This assures users that their sensitive information will not be intercepted or tampered with while being transmitted.

Other options touch on related but distinct functionalities of web security and server operations which are not the main purpose of an SSL certificate.
