The function of an SSL certificate primarily revolves around establishing a secure channel between a user's web browser and a server. This is achieved through two critical roles: authentication and encryption. With an SSL certificate, the identity of the website is validated, establishing trust between the user and the site. This authentication ensures that users are communicating with the genuine website they intend to contact, reducing the risk of man-in-the-middle attacks or phishing scams.

Additionally, the SSL certificate facilitates an encrypted connection. This means that any data exchanged between the user's browser and the server is encrypted, protecting sensitive information such as login credentials, credit card numbers, and personal messages from being intercepted by unauthorized parties. This combination of authentication and encryption makes SSL certificates essential for any website handling sensitive data, creating a safer online experience for users.
