SSL (Secure Sockets Layer) is a security protocol used to establish an encrypted link between a web server and a browser, ensuring that data passed between them remains private and secure. Although SSL has been largely replaced by the more secure TLS (Transport Layer Security), the term "SSL" is still commonly used.

The primary purposes of SSL (or TLS) include:

    Data Encryption: SSL encrypts data exchanged between a web server and a browser, making it unreadable to anyone who intercepts the communication. This ensures that sensitive data, like passwords, credit card information, and personal details, is kept secure during transmission.

    Authentication: SSL certificates help verify the identity of the website, ensuring that users are connecting to the legitimate site and not a malicious one (such as phishing sites). This is done through a process where the website proves its identity using a public key certificate.

    Data Integrity: SSL ensures that the data sent between the server and the client is not altered during transmission. Any tampering with the data would be detected.

    Trust Indicators: Websites that use SSL are often identified with a padlock icon in the browser's address bar and use "HTTPS" (HyperText Transfer Protocol Secure) instead of "HTTP." This helps users trust that the website is secure.

Overall, SSL/TLS plays a crucial role in securing online communication, protecting sensitive information, and building trust between websites and their users.
