What is the main function of SSL?

The main function of SSL (Secure Sockets Layer), now largely succeeded by TLS (Transport Layer Security), is to provide security when communicating over the Internet. SSL establishes an encrypted link between a web server and a browser, ensuring that any data transmitted remains private and secure. This encryption protects against eavesdropping, tampering, and forgery, making it essential for activities that involve sensitive information, such as online transactions, personal data exchanges, and secure communications.

By validating the identity of the parties involved in the connection and encrypting the information, SSL plays a critical role in building trust and safety in various Internet interactions. This is particularly important in today’s digital landscape, where data breaches and cyber threats are common.
