[tor-dev] [404] :-( Retrieving Hidden Service Public-Key ...

[Gareth Owen]

The request to the dirport definitely has to come via tor not via a simple
request to the dirport over the net.

Have a look in the HiddenService class here for an example:

https://github.com/drgowen/tor-research-framework/blob/master/src/main/java/tor/HiddenService.java

Its fairly easy to use this function if you just want to fetch the
descriptor for an arbitrary HS.  Have a look at the repository hidden
service example. You just need a valid TorSocket and then you can call
HiddenService.fetchHSDescriptor () to get it as a string.
