What is TLS? How does it differ from SSL?

TLS (Transport Layer Security) is a cryptographic protocol that ensures the security of data transmission over a network, including encryption, authentication, and integrity.

SSL (Secure Sockets Layer) is the predecessor of TLS. TLS is a more modern, secure, and standardized version of SSL. Main differences:

• TLS improved encryption algorithms and eliminated vulnerabilities present in SSL.
• SSL versions 2 and 3 are considered outdated and insecure.
• TLS version 1.0 and above are the current standards for secure connections.

Essentially, TLS is an updated and more secure protocol that has replaced SSL.
