SSL encryption is a type of security protocol that encrypts data sent over the internet. It creates a secure connection between two systems, such as a web server and a web browser, so that any data sent between them is unreadable by anyone else.
For example, when you make a purchase online, the website you are using will use SSL encryption to protect your personal information, such as your credit card number, name, and address. The website will encrypt this data before it is sent over the internet, making it unreadable to anyone who intercepts it. When the data reaches its destination, the server will decrypt the data so that it can be read.
