tor-llcrypto: key blinding: Use consistent terminology

2023-03-28T11:47:12Z

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.

Use the type system to enforce use of blinded keys.

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. Signed-off-by: Gabriela Moldovan

Add builder for encoding hidden service descriptors.

2023-03-24T18:57:49Z

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.

Suppress a renamed-lint lint.

2023-03-10T12:09:50Z

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.

Expose a little new functionality from tor-llcrypto.

Expose ED25519 signature length; make ValidatableEd25519Signature implement Debug and Clone.

Allow clippy::unchecked_duration_subtraction in tests

2023-01-27T13:28:02Z

This panics on error, and we're fine with a panic on misbehavior in tests.

Disable clippy::unlinlined-format-args

2023-01-27T13:27:47Z

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.
