#31369: HSv3 descriptor support in stem -------------------------------+----------------------------------------- Reporter: asn | Owner: atagar Type: defect | Status: new Priority: Medium | Milestone: Component: Core Tor/Stem | Version: Severity: Normal | Keywords: tor-hs onionbalance scaling Actual Points: | Parent ID: Points: | Reviewer: Sponsor: Sponsor27-can | -------------------------------+----------------------------------------- Hello,
it would be great if stem could support v3 onion service descriptors: both to parse them and to generate them. This would be particularly useful as part of onionbalance v3 (#26768). The old onionbalance actually generates the descriptors itself in an ad-hoc way, but it would be great if we could have stem make them in the new one. Damian asked me for an HSFETCH command that will fetch a stable v3 onion desc. I used Donncha's script from here (https://gist.github.com/DonnchaC/13b744a1e30b7d34bc26) like this: `python tmp/hsfetch.py vww6ybal4bd7szmgncyruucpgfkqahzddi37ktceo3ah7ngmcopnpyyd.onion` and that gives me the riseup onion descriptor (there is no DDG v3 onion right now). Also, v3 descriptors are more complicated than v2 descriptors because of their double-layer encryption. You can see more info here: https://github.com/torproject/torspec/blob/master/rend-spec-v3.txt#L1046 https://github.com/torproject/tor/blob/0acfd7dcee2a4473eba05a53d6df2d6d4fe2050b/src/feature/hs/hs_descriptor.c#L2639 Damian, let me know how that looks like to you and how we can help. We plan to start working on Onionbalance v3 at mid-to-late August, but if this is something we can have at a reasonaable timeframe we can potentially delay the descriptor parts of it for some time until stem support exists. -- Ticket URL: <https://trac.torproject.org/projects/tor/ticket/31369> Tor Bug Tracker & Wiki <https://trac.torproject.org/> The Tor Project: anonymity online
