I want to replay some real traffic and send it through Tor to collect Tor encrypted traffic. From what I have read so far, the shadow simulator or a private Tor testbed seem to be the best and safest options for this. I additionally plan to host a private hidden service and collect traffic at the hidden service end as well. But I haven't used any Tor experimentation tools before, and I would like some information on the feasibility of using the above 2 methods for my scenario. Any other suggestions are also welcome.
