<|fim_im_start|>` TLS (Transport Layer Security) is a protocol used across the globe to encrypt and secure communication over the internet. TLS and its predecessor SSL are the most commonly used cryptographic protocols for providing encryption, authenticity, and integrity, enabling end-to-end security of data sent between applications over the internet. The importance of TLS lies in protecting against man-in-the-middle attacks, providing integrity protection, authentication, and confidentiality of data exchanged between clients and servers. To implement TLS in Java, developers use the JSSE (Java Secure Socket Extension) framework, which abstracts the underlying implementation of transport layer security protocols, allowing easy implementation of secure encrypted communications between clients and servers. The client-side implementation involves creating a socket using SSLSocketFactory, while the server-side implementation uses SSLServerSocketFactory to initiate the connection.
