What is the primary purpose of the Secure Socket Layer (SSL)?

The primary purpose of the Secure Socket Layer (SSL) is to secure communication over a computer network. SSL achieves this by establishing an encrypted link between a server and a client, ensuring that any data transferred remains confidential and is protected from eavesdroppers or tamperers during transit. This encryption helps safeguard sensitive information such as personal data, passwords, and credit card details from being intercepted by malicious actors.

SSL also employs a system of certificates to authenticate the server, allowing users to verify that they are indeed communicating with the intended server rather than a fraudulent one. While user authentication is an important aspect of SSL, it is not its primary purpose. By securing communication, SSL enhances trust in online transactions, providing a secure foundation for various protocols like HTTPS, where web security is paramount.
