TLS 1.3 Approved…. Here’s Why You Should Care

If you’re worried about privacy on the Internet, then the final approval TLS 1.3 should matter to you. TLS 1.3 will make it much harder for eavesdroppers to decrypt intercepted traffic. But at the same time it’s a drop-in replacement for TLS 1.2 as it uses the same keys and certificates and clients and servers can automatically negotiate TLS 1.3 when they both support it. So that means that getting TLS 1.3 into the world should be quick. In fact both Firefox and Chrome already support a draft version of TLS 1.3 if you’re on the latest and greatest from either browser maker. TLS 1.3 is also less resource hungry and more efficient, meaning you should be able to both reduce latency and benefit from lower CPU usage. Or put another way, surfing the net will become a touch faster.

One of the big drivers behind the creation of TLS 1.3 is all the NSA revelations from a few years ago. Thus the big losers in this are spies and those who want to do evil things on the Internet – at least until they figure out a way to crack this new protocol. At which point the IETF will start on TLS 1.4.
