SSL (Secure Sockets Layer) and TLS (Transport Layer Security) are both cryptographic protocols that provide secure communication over the internet. The main difference between SSL and TLS is that SSL is now deprecated and TLS is the current standard.
SSL is a protocol that was developed by Netscape in the 1990s and was used to secure data transmission between a web server and a web browser. It used a combination of encryption, authentication, and message integrity to secure data.
TLS is an upgraded version of SSL. It was developed in 1999 and is now the standard protocol for secure communication on the internet. TLS is more secure than SSL and uses stronger encryption algorithms to secure data and provide better authentication. It also supports newer features such as perfect forward secrecy and elliptic curve cryptography.
