What type of actions does an SSL certificate support?

An SSL certificate supports a range of actions primarily focused on creating secure websites and connections. The main function of an SSL (Secure Sockets Layer) certificate is to establish an encrypted link between a web server and a browser. This encryption ensures that any data transmitted between the two remains private and secure from potential eavesdropping or tampering.

When a website has an SSL certificate, it utilizes HTTPS (Hypertext Transfer Protocol Secure), which is the secure version of HTTP. This protection is essential for websites that handle sensitive information, such as login credentials, personal data, or payment details, thus gaining users' trust as their information is protected during transmission.

In contrast to the other options, the SSL certificate does not specifically focus on email encryption, limiting the access of trusted sources, or enhancing the visual aspects of a website. Rather, its primary role is to secure online communications, making it crucial for e-commerce, online banking, and various types of web applications requiring data security.
