Starting today, with the 1.13.0-dev.1.0 release of the Dart SDK, the Dart VM has upgraded its TLS/SSL implementation to BoringSSL . The BoringSSL library is a fork of OpenSSL that’s created and maintained by Google. Dart developers now have the same implementation of SSL as Chromium and Chrome.The new implementation includes some breaking changes to the SecureSocket class and related classes. Dart programs that create secure servers will need to provide their server certificate chain and private key in a new, and easier, way.We encourage you to try the dev channel build of Dart SDK and the new configurations for BoringSSL. You can learn more about Dart and TLS/SSL , and we look forward to your feedback
