Re: [tor-relays] descriptor-id calc tool?

Is there a tool out there that tells me which HSDir is/will probably be responsible for a given onion address (and at what time)?

There's no tool, unless you can reverse SHA1. (Or brute-force a set of popular onion addresses.)

I probably was not very clear in my question. I'm not aiming for the reverse path, just the normal calculation a tor client does given an onion address but instead of just calculating the current descriptor-id, print descriptor-ids for the future N days for onion address M (for the pre-prop224 world).

For the "current-only" case you might use stem: https://gist.github.com/nusenu/8339cfd5351b64c47676241a40ee2942
