Use Psiphon when Tor bridges are not reachable
We have been encouraged to use Psiphon as a circumvention technology.
Here's how to add it:
- Start the Psiphon Library and get its SOCKS proxy port
- Configure the Tor client run by Briar to proxy through Psiphon using the "Socks5Proxy" config setting (https://www.torproject.org/docs/tor-manual.html.en)
- The Tor client traffic egresses from the Psiphon server, connects to a Tor node, and gets to hidden services from there. Psiphon doesn't need to know about the hidden service part.
