Internet Explorer 11 and legacy Microsoft Edge users will potentially retain default TLS 1.0 and 1.1 support for a bit longer:įor all supported versions of Internet Explorer 11 and Microsoft Edge Legacy (EdgeHTML-based), TLS 1.0 and TLS 1.1 will be disabled by default as of September 8, 2020. Originally planned for the first half of 2020, Microsoft will now disable legacy TLS in Chromium-based Edge with the release of version 84.įor the new Microsoft Edge (based on Chromium), TLS 1.0 and 1.1 are currently planned to be disabled by default no sooner than Microsoft Edge version 84 (currently planned for July 2020). In an announcement at the end of March, Microsoft said that it would delay disabling legacy TLS protocols by default in all its supported browsers. Microsoft postpones support for dropping legacy TLS in its browsers So, the only choice is to upgrade to a newer version of the protocol.
Neither TLS 1.0 or 1.1 let peers select a stronger hash for signatures in the ServerKeyExchange or CertificateVerify messages than SHA-1. TLS 1.2 with SHA-1 as a signature should also not be used. The Internet Engineering Task Force (IETF) says TLS 1.0 and 1.1 shouldn’t be used.
