Apple, Google, Microsoft and Mozilla Announce Discontinuing TLS 1.0 and 1.1 Support
By Palash Verma
In the first half of 2020, all major browsers (Safari, Chrome, Edge, Internet Explorer and Firefox) will no longer support TLS 1.0 and 1.1 standards. These plans were voiced by manufacturers of Internet browsers, Apple, Google, Microsoft and Mozilla.
“TLS 1.0, the first version of the protocol that encrypts and authenticates secure connections via the network, is being celebrated on January 19 of next year. Implementations of TLS 1.0 and TLS 1.1, vulnerabilities in third-party implementations exist. Moving to newer versions helps to provide a safer Internet for everyone,” Microsoft said in a blog post.
TLS 1.0 and 1.1 relies on unreliable MD5 and SHA-1 algorithms. These versions account 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, full support will be discontinued in early 2020 with the release of Chrome 81. Edge and Internet Explorer 11 will stop supporting the outdated protocol in the first half of 2020, Firefox and Safari in March same year.
All of the above browsers support TLS version 1.2, Chrome and Firefox already have support for the TLS 1.3 standard. Apple and Microsoft are still working on the implementation of this version in their browsers.
Transport Security Layer (TLS), developed using the Secure Sockets Layer (SSL) protocol, is an updated cryptographic protocol used to establish a secure and encrypted communication channel between clients and servers.
