Although the TLS 1.3 encryption protocol has been around for a long time, in the RFC series of the Internet Engineering Task Force, we still carry the older and insecure TLS 1.0 and TLS 1.1 protocols with us in every application we use.
Older versions of Transport Layer Security 1 and 1.1 (dating back to 1999 and 2006 respectively) are almost no longer in use, but Dell EMC's Stephen Farrell and Kathleen Moriarty of Trinity College Dublin insist on their formal abolition.
The Draft which has the URL "die die die" argues that the time to remove the protocols should not be somewhere in the future, but now, because developers need something to convince companies to update their projects.
The abolition of ancient protocols will nullify any excuse for projects that require support for all variants of TLS (up to TLS 1.3), greatly simplifying the lives of developers and reducing the risk of application errors using them.
It should be mentioned here that the abolition deadline given by the PCI Council expires on June 30, 2018.
The draft also states that in addition to websites, organizations such as 3GPP 5G, CloudFlare, Amazon and GitHub should all have completed the removal, with one last extension in July.
