In the first half of 2020 all major browsers (Safari, Chrome, Edge, Internet Explorer and Firefox) by default will cease to maintain the standards of TLS 1.0 and 1.1. These plans was voiced by the producers of Internet browsers, Apple, Google, Microsoft and Mozilla.

“January 19 next year marks 20 years since TLS 1.0, the first version of the Protocol that encrypts and authenticates a secure connection through the network […] Two decades is a long time for safety technology remained unchanged. Although we do not know about the vulnerabilities in our modern implementations of TLS 1.0 and TLS 1.1, vulnerabilities in third-party implementations exist. The transition to the newer version helps to ensure a safer Internet for all”, — stated in the Microsoft blog.

TLS 1.0 and 1.1, is based on unreliable algorithms MD5 and SHA-1. These versions accounted for only about 0.5% of all HTTPS connections.

Google intends to start disabling TLS 1.0 and 1.1 with the release of Chrome 72, fully support will be discontinued in early 2020 with the release version of Chrome 81. Edge and Internet Explorer 11 stop supporting a legacy Protocol in the first half of 2020, Firefox, and Safari in March of the same year.

All the above browsers support TLS version 1.2, in Chrome and Firefox already have support for the standard TLS 1.3. Apple and Microsoft are still working on the implementation of this version in their browsers.

Transport layer security (TLS), is developed based on the Secure Sockets Layer (SSL) is an updated cryptographic Protocol used to establish a secure and encrypted channel of communication between clients and servers.
