The final version of TLS 1.3 (Transport Layer Security) just released by the IETF (from the Internet Engineering Task Force) and popular browsers such as Chrome and Firefox already support the new security standard.
TLS 1.3 is a very significant update to TLS 1.2 despite the minor change in version number. The Layer Security Transport standard is used by Appliances for secure transactions on the Internet. Basically, when you see an HTTPS connection you should know that it uses the TLS standard. Whether TLS 1.3 is already used (some beta version of it because the final version has just been released) or TLS 1.2 depends on the browser and the website you are visiting.
Many beta versions of TLS 1.3 have been released in recent years as the new security standard is being developed. Mozilla and Google's browser development teams have started to support the new template since its development was still in the experimental stages.
So there are already some websites that use Transport Layer Security 1.3. Mozilla reports that about 5% of Firefox connections already use the TLS 1.3 standard and that companies like Google, Facebook or Cloudflare already support TLS 1.3. Note that iGuRu.gr also supports links to TLS 1.3.
What makes TLS 1.3 (Transport Layer Security) different?
The TLS 1.3 as mentioned above is an important update that greatly improves speed and security. One of the main advantages of TLS 1.3 is that basic handshakes perform a single round-trip compared to TLS 1.2's double round trip. So the time it takes to connect to servers that support TLS 1.3 is reduced and websites that support TLS 1.3 are loading faster on browsers that support the new template.
Security has also been improved in Transport Layer Security 1.3 compared to previous versions. TLS 1.3 focuses on a few well-known algorithms encryptionς, ενώ το ΤLS 1.2 μπορεί να περιλαμβάνει support for more algorithms, but some of them have been hacked before.
TLS 1.3 encrypts most of the handshake that improves privacy while connecting to servers, as many of the information that was open with TLS 1.2 is now encrypted and non-readable during transport.
For those interested above, Cloudflare published one technique overview of Transport Layer Security 1.3 at blog of the company.
