For these crates, the changes are nontrivial, so we
_do_ bump the versions on which their dependent crates depend.
Fortunately, since they are all pre-1.0, we don't need to
distinguish semver-additions from other changes. (Except for arti,
which _is_ post-1.0, but gets a patchlevel bump anyway.)
These are unstable crates with breaking changes:
```
tor-hscrypto
tor-hsclient
```
These have new or extended APIs:
```
safelog
tor-bytes
tor-cell
tor-linkspec
tor-llcrypto
tor-proto
tor-cert
arti-client
```
These have new unstable APIs or features:
```
tor-netdoc
tor-circmgr (also broke some unstable APIs)
arti (is post-1.0)
```
These have bugfixes only:
```
caret
tor-dirmgr
```
Unhelpfully, the spec uses the variable name `h` and the phrase
"blinding factor" for both the unclamped and clamped value. The
clamped value is internal to the algorithm.
In our code:
* Don't ever use the word "parameter" or variable name `param`.
This doesn't appear in the spec anywhere.
* Use `h` for the unclamped blinding factor, and `blinding_factor` for the
clamped blinding factor.
* Rename `blinding_factor` function to `clamp_blinding_factor`, since
in the spec's terminology it takes an (unclamped) "blinding factor"
and returns a (clamped) "blinding factor".
* State explicitly what thing in the spec the `h` parameters are.
Hidden services use blinded singing keys derived from the identity key
to sign descriptor signing keys.
Before this patch, the hidden descriptor builder represented its blinded
signing keys (`blinded_id`) as plain `ed25519::Keypair`s. This was not
ideal, as there was nothing preventing the caller from accidentally
initializing `blinded_id` with an unblinded keypair.
This introduces a new `HsBlindKeypair` type to represent blinded
keypairs.

This introduces the `NetdocBuilder` trait described in
`netdoc-builder.md` and a new `tor-netdoc::doc::hsdesc::build` module,
which exports the `HsDescBuilder`. Hidden services will use
`HsDescBuilder` to build and encode hidden service descriptors.
There are several TODOs in the code that I'm planning to address
separately.
Partially addresses #745.

The derive_hash_xor_eq lint was renamed in 1.68, but we can't use
it under its new name, since we still need to support back to 1.60.
Instead, we suppress the warning about the lint being renamed.
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
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.
This is in lieu of upgrading to the latest base64 crate, which has
a different API from the old one. Since we have to migrate either
way, we might as well use base64ct everywhere.
I don't think that most of these cases _require_ constant-time
base64, but it won't hurt.
The `Ed25519Identity` and `RsaIdentity` types are not precisely
always used as relay identifiers: they are more generally used as
_key_ identifiers.
This will become relevant as `RsaIdentity` is used for authority
keys (as in authorities' VoterInfo blocks), and as `Ed25519Identity`
is used as the identifier behind an onion service key.
Closes#719.
Due to a difference between ed25519-dalek and ed25519-donna,
converting these secret keys directly to public keys does not work.
I've documented this in a "Limitations" section.
This type provides a common implementation for types that are
implemented as arrays of bytes that should only be compared
with constant-time comparisons.
As near as I can tell, the rust-crypto SHA1 crate was called `sha-1`
for a while because of a conflict with a different SHA1 crate. Now
they apparently have the `sha1` name back and have deprecated the
`sha-1` name.
The feature we want is `#[doc = include_str!("README.md")]`, which is
stable since 1.54 and our MSRV is now 1.56.
This commit is precisely the result of the following Perl rune:
perl -i~ -0777 -pe 's{(^//!(?!.*\@\@).*\n)+}{#![doc = include_str!("../README.md")]\n}m' crates/*/src/lib.rs
