As noted on its WebKit blog. Apple says it plans to move from Transport Layer Security (TLS) 1.0 and 1.1 to modern, more secure protocols.
WebKit is a layout engine software component for rendering web pages in web browsers. It powers Apple’s Safari web browser. TLS is a protocol that provides privacy and data integrity between two communicating applications. It’s the most widely deployed security protocol and is used for Web browsers and other applications that require data to be securely exchanged over a network.
However, in its WebKit blog post, Christopher Wood of Apple’s Secure Transports Team says it’s important to use modern and more secure versions of this protocol. Specifically, applications should move away from TLS 1.0 and 1.1.
“Therefore, we are deprecating support for TLS 1.0 and 1.1,” he writes. “Complete support will be removed from Safari in updates to Apple iOS and macOS beginning in March 2020. Firefox, Chrome, and Edge are also planning to drop TLS 1.0 and 1.1 support at that time. If you own or operate a web server that does not support TLS 1.2 or newer, please upgrade now.”
