TLS 1.3 is the latest version of the Transport Layer Security (TLS) protocol, which is used to secure communications between two computers over the internet. TLS 1.3 is designed to be faster and more secure than its predecessors, TLS 1.2 and TLS 1.1. It is the first major update to the TLS protocol since 2008.
TLS 1.3 is designed to be faster than its predecessors by reducing the number of round trips required to establish a secure connection. It also reduces the amount of data that needs to be exchanged between the two computers. This makes it more efficient and reduces the time it takes to establish a secure connection.
TLS 1.3 is also more secure than its predecessors. It uses stronger encryption algorithms and adds additional security features such as Perfect Forward Secrecy (PFS) and 0-RTT (Zero Round Trip Time) to protect data in transit. It also adds support for modern cryptographic algorithms such as ChaCha20-Poly1305 and AES-GCM.
TLS 1.3 is already supported by most major web browsers and web servers. It is also supported by many popular email clients and other applications. As more applications and services adopt TLS 1.3, it will become the standard for secure communications over the internet.
