What does SSL stand for, and why is it used?

SSL stands for Secure Socket Layer, which is a standard technology used to create a secure encrypted connection between a web server and a client, typically a web browser. This encryption is crucial for protecting sensitive data, such as personal information, credit card details, and other confidential communications from eavesdroppers and cyber attackers during transmission over the internet.

The use of SSL ensures that the data exchanged remains private and integral, preventing third parties from intercepting or altering the information. This technology operates by utilizing a combination of public key and symmetric key encryption to establish a secure session, which is essential for maintaining trust and security in online transactions and communications.

Understanding SSL is fundamental, especially in the context of web security protocols. It underpins the operation of HTTPS, the secure version of HTTP, further enhancing security for websites that handle sensitive transactions.
