tor-llcrypto: remove use of arrayref

2023-06-01T14:50:25Z

llcrypto: Add an `ed25519::ExpandedKeypair` type.

2023-05-18T14:56:43Z

This is like an `ed25519::Keypair`, except that instead of a `SecretKey` it contains an `ExpandedSecretKey`. We'll be using this to implement #798, where we impose a rule that there must be no "unescorted" ed25519 secret keys.

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

Expose a little new functionality from tor-llcrypto.

2023-02-28T16:23:44Z

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

llcrypto: Implement `Into<[u8;32]>` for Ed25519Identity

2023-02-07T14:00:19Z

Complete our migration to base64ct.

2023-01-20T13:06:30Z

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.

llcrypto: clarify meaning of "Identity".

2023-01-06T18:03:47Z

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.

Add a new "CtByteArray" type, and use it in Id types.

2023-01-05T17:34:14Z

This type provides a common implementation for types that are implemented as arrays of bytes that should only be compared with constant-time comparisons.

llcrypto: Make key id types Redactable.

2022-11-28T13:01:10Z

Define a constant for ED25519 identity length.
