SSL (Secure Sockets Layer) encryption is a protocol used to secure communication between web browsers and servers. SSL encryption works by creating a secure and encrypted connection between the browser and the server, allowing for the safe transmission of data over the internet.

When SSL encryption is used, a user’s browser and a server establish a secure connection through a process known as a “handshake.” During the handshake process, the browser and the server agree on a set of security protocols, including the type of encryption to be used, and exchange digital certificates to authenticate their identities.

Once the secure connection is established, all data transmitted between the browser and the server is encrypted and cannot be intercepted or read by third parties. This helps to protect sensitive information such as passwords, credit card numbers, and personal information from being stolen or intercepted by hackers.

SSL encryption is commonly used on e-commerce websites, banking websites, and other sites that require secure communication between the user’s browser and the server. In recent years, SSL encryption has been replaced by the more secure TLS (Transport Layer Security) encryption protocol, which provides stronger encryption and better protection against modern cyber threats.
