Provide a more cookied "secret keys for use to connecting to a
particular HS" type, with a builder.
This wants to use config stuff, so oughtn't to be in tor-*crypto.
The individual types remain there.
These crates have had small code changes, but no API additions:
tor-config
tor-socksproto
tor-cert
tor-chanmgr
tor-ptmgr
tor-guardmgr
tor-circmgr
tor-dirclient
tor-dirmgr
arti
tor-hsservice
tor-congestion
These crates have had API extensions:
fs-mistrust
tor-llcrypto
tor-bytes
tor-checkable
tor-linkspec
tor-netdoc
tor-persist
arti-client
These are API breaks, but the crates themselves are currently
100% experimental, so there's no need to bump the minor versions
according to our semver rules.
Fixes an instance of #768.
The problem with the test vectors is that I used a random time
period number (1234) and the default-in-tor period length (1440)
without checking whether 1440 _meant_ minutes or seconds. I'll add
another test to Tor to make sure that the time period matches now.
With this change, I can test Tor-generated hsdescs with encryption,
so I'm fairly confident that the new behavior is correct.
Locally, the only functional effect is that now we refuse to handle
non-whole-number-of-minutes lengths - but since the consensus
parameter can't represent those, there's no overall functional change.
This logic is a bit tricky, so I've tried to document it and add
fairly good tests. The silver lining is that the external API for
all of this logic will make it invisible and hidden.
There are some cases where I added functions that I think might
eventually get lowered into MdConsensus: But I don't want to lower
too much right now, since the convention for our netdoc accessors is
that they are fairly unsophisticated, and they show you the document
as it is.
Closes#686
This warning kind of snuck up on us! (See #748) For now, let's
disable it. (I've cleaned it up in a couple of examples, since
those are meant to be more idiomatic and user-facing.)
Closes#748.
It turns out that the credential is only calculated as an
intermediate result in order to blind keys and produce the
subcredential. As such, it has no need to leave the hscrypto module.
Previously, the offset was set to 12 hours unconditionally (like the
spec says). But based on a conversation on tor-dev, it seems that
the offset should actually be 12 times the voting interval.
I'm also opening an MR to change the spec.
These are a bit complex internally, but the API they present is
pretty simple. I've left some discussion of points where the design
isn't totally fleshed out, and where we need to look harder at the
spec.
Part of #716.
This module has types and operations needed in multiple places
for an onion service implementation. There are a bunch of
TODO hs-crypto comments that we'll need to fill in.
