For example, I downloaded Tor network and using it for illegal activities. Can my govt track me? Can US govt track me? With Signal fiasco, I can’t trust softwares that I’m not familiar with.
I know it encrypts something but if I remember correct, FBI was able to find some Tor users before.
Note: illegal activities was for example. I’m not going to do anything illegal. I’m just planning to serve my instance with a onion address.
TOR is as secure as you want it to be.
It isolates all traffic from your ISP. HOWEVER. It is not always endpoint secure (where the endpoint node exits to the general internet) because anyone can run an endpoint. Its well known that the US government themselves runs a lot of TOR endpoint nodes to vacuum up traffic. And of course any accounts/identifiers you use will still be traceable.
It is certainly much better than clearnet. But it’s not perfect, and it’s also slow as balls (never seen an exit relay run faster than 200kb/s)
I use OnionShare purely because I like to be fully in control of my stuff, and aware of the resources I’m consuming… I trust that it’s secure and private, though I’m not doing anything illegal.
For comms, I like to use Tox, though I don’t think there’s an iOS app, which limits things somewhat.
