This changes the TLS and certificate handling in a few ways: - We always use TLS 1.2, both for sync connections (as previously) and the GUI/REST/discovery stuff. This is a tightening of the requirements on the GUI. AS far as I can tell from caniusethis.com every browser from 2013 and forward supports TLS 1.2, so I think we should be fine. - We always greate ECDSA certificates. Previously we'd create ECDSA-with-RSA certificates for sync connections and pure RSA certificates for the web stuff. The new default is more modern and the same everywhere. These certificates are OK in TLS 1.2. - We use the Go CPU detection stuff to choose the cipher suites to use, indirectly. The TLS package uses CPU capabilities probing to select either AES-GCM (fast if we have AES-NI) or ChaCha20 (faster if we don't). These CPU detection things aren't exported though, so the tlsutil package now does a quick TLS handshake with itself as part of init(). If the chosen cipher suite was AES-GCM we prioritize that, otherwise we prefer ChaCha20. Some might call this ugly. I think it's awesome. |
