TLSv13

TLSv13, also known as Transport Layer Security version 1.3, is the latest major revision of the security protocol used to secure communications over a computer network. It builds upon its predecessors, TLSv1.2 and earlier versions, to provide enhanced security, performance, and privacy. One of the key improvements in TLSv1.3 is a simplified handshake process. This reduction in the number of round trips between the client and server makes establishing a secure connection faster, leading to improved latency, especially for users with high-latency connections.

TLSv1.3 also removes several outdated and less secure cryptographic algorithms, such as static RSA key exchange and SHA-1. This hardening of the protocol makes it more resistant to various attacks. The removal of these older features simplifies implementation and reduces the attack surface. Furthermore, TLSv1.3 offers improved forward secrecy by default, meaning that even if a server's long-term private key is compromised in the future, past communication sessions encrypted with TLSv1.3 will remain secure. The protocol also enhances privacy by encrypting more of the handshake traffic, making it harder for network observers to glean information about the connection, such as the specific cipher suite being used. These advancements make TLSv1.3 the current standard for secure web browsing and other internet communications.
