Hi Matt,
We recently started experimenting with the Salmon social bridge distributor: https://gitlab.torproject.org/tpo/anti-censorship/bridgedb/-/issues/31873
We are now exploring the possibility of storing some Salmon-related data on a user's computer and are wondering what our options are. The data we're talking about is a lightweight, signed, and encrypted blurb that contains a user's social graph, proxies, and registration ID.
One option to store this data is Tor's data directory but that doesn't seem ideal because Salmon isn't a PT and technically has nothing to do with Tor. Is Tor Browser an option here? Or does the "disk avoidance" design goal mean that we don't get to store anything at all? A last resort option would be to simply hand the blurb to the user and ask them to store it somewhere but we would like to find a more usable way to handle this.
Thanks, Philipp
