| [https://github.com/mozilla/tls-observatory Mozilla TLS Observatory] is a hosted service that provides hindsight and compliance checking on the configuration of HTTPS servers. The goal of this project is to rewrite the [https://github.com/mozilla/cipherscan ciphersuite scanner] in Rust to support scanning TLS 1.3, but also maintain the ability to scan old version of TLS, all the way back to SSL2.0. This will likely require interacting with older versions of OpenSSL. Performance is also a strong requirement for this project. TLS Observatory scans thousands of sites every hour, and saving precious seconds on each scans make a big difference to the infrastructure. Finally, because this is a replacement of Cipherscan, this project requires maintaining backward compatibility with integrations that rely on specific flags, or json outputs. The final goal is to ship this project into the production infrastructure of TLS Observatory.

| Cipherscan is the measuring tool that Mozilla uses to keep on eye on TLS configurations across the Internet. It is instrumental to the TLS guidelines work we do over at [https://wiki.mozilla.org/Security/Server_Side_TLS Server Side TLS]. This project will directly contribute to tooling that operators rely on worldwide to keep their websites secure.
