[Moving this thread to tor-dev as suggested by Damian in separate mail.]
Hi Damian, hi Beck,
There are quite a few options.
How about extending stem to implement #2768? There's already Java code
for verifying server descriptors and consensuses in metrics-tasks.git
[0]. On stem's side this requires parsing the crypto parts of server
descriptors, consensuses, and certificates. If the network statuses
aren't there yet, starting with server descriptors should be fine. And
once there's verification code for server descriptors and consensuses,
there are more things to verify in Tor's various descriptors.
Another option would be to write the parsing code for extra-info
descriptors including all the stats. Once we have consensuses, server
descriptors, and extra-info descriptors in stem, we can start writing a
Python version of Onionoo [1], the service that provides the data for
Atlas [2].
Let me know if you need more options or more input on these.
Thanks,
Karsten
