SSL (Secure Sockets Layer) is a protocol used to protect data sent between two systems, such as a web server and a web browser. It uses encryption to protect data from being intercepted by malicious actors.
For example, when a user visits a website, the web server and the user’s web browser will establish an SSL connection. All data sent between the two systems is encrypted, meaning that any malicious actors who might be listening in on the connection will not be able to read the data. This helps to protect the user’s data, such as passwords and credit card numbers, from being stolen.
