Additionally, the vetting process takes an eternity when there are this many stakeholders involved. There were problems with middleboxes, there were commercial elements looking to undermine the standard in the interest of traffic inspection. It was not always smooth sailing, either.

TLS 1.3 ( RFC 8446) was released a full decade after TLS 1.2 and took 28 drafts to finally define.

So, today we’re going to take a look at what exactly has changed in TLS 1.3 and what benefits those changes bring to security and performance on the web. While, intuitively it would seem that the biggest difference between two successive protocol versions would be the switch from SSL 3.0 to TLS 1.0, it’s probably fair to argue that TLS 1.3 is far more different from TLS 1.2 than 1.0 is from SSLv3. TLS 1.0 was replaced by 1.1, which was succeeded by TLS 1.2 two years later in 2008. There were some technical differences between SSL and TLS – namely, at first, whether the connection began by port or by protocol – but the premise was largely the same. And then TLS 1.0 was introduced as a replacement to SSL. SSL 1.0 was never officially released, 2.0 and 3.0 were short-lived ( albeit not entirely dead yet). Technically, TLS 1.3 is the seventh iteration of the SSL/TLS protocol. But we realized we hadn’t done an in-depth explainer of the new protocol version yet, and given the number of questions we field about TLS 1.3 on a regular basis – we thought maybe this would be a good time. In Everything Encryption TLS 1.3 has myriad improvements over its predecessors, including a new handshake and revamped cipher suites.īefore anyone points out that the IETF published TLS 1.3 as RFC 8446 almost a year ago – we know.
