Description

Tor users are prevented from creating a transparent proxy due to bug https://github.com/keybase/client/issues/9757. This means our IP address is being leaked to the centralized keybase server. This happens even if --tor-mode= is supplied by client transactions because the local server is also listening for web-triggered chat requests.

Consequently, there is a need for proper Tor support. The server should establish a .onion address and use Tor to register the .onion address with the server at keybase.io.

The seriousness of this bug is sharp, in light of the fact that users don't even necessarily know they are running a server (ref https://github.com/keybase/client/issues/3869).

Research direction

Start by reading the linked issues 9757 and 3869 to understand the transparent-proxy failure and when users unknowingly run a server. Done would require the server to establish a .onion address and register that address with keybase.io through Tor.
