dalek-cryptography is still on rand 0.8, so we need a compatibility
shim for the Rng.
Fortunately, since we merged interface-abstraction-of-the-daleks
(!2868), we no longer need to propagate this compatibility layer
throughout our codebase.
Wrap x25519-dalek types.2025-03-17T18:40:17ZNick Mathewsonnickm@torproject.org2025-03-17T18:31:42Zurn:sha1:6f5ad88ec515c95a632ed2c582d4ca61d89247af
With this change, we'll no longer need to expose the types from
dalek-cryptography as part of our API, and we'll have more freedom
to switch curve25519 implementations, or to upgrade to a newer
`rand` ahead of their schedule.

The main changes that we have to adjust for are as follows:
* In x25519-dalek:
* `StaticSecret` is now behind a feature.
* `StaticSecret::new` is deprecated in favor of
`StaticSecret::random_from_rng`.
* StaticSecret no longer does its own clamping.
* In ed25519-dalek:
* `SecretKey` has (in effect) been renamed to `SigningKey`. The name
`SecretKey` is now an alias for `[u8; 32]`.
* `SigningKey` is effectively a keypair, since it contains a
public key as well.
* `PublicKey` has been renamed to `VerifyingKey`.
* The functions to extract a signing key and verifying key have
been renamed as you might expect.
* `ExpandedSecretKey` has been moved to `hasmat` and no longer
implements `sign`.
* `ExpanededSecretKey` now has as its elements a scalar and a hash
prefix.
* Various functions that took `&[u8]` now take `&[u8; N]`.
* We no longer need a wrapper for older versions of rand.
There is a single test in tor-keymgr that does not pass. I've
marked it as ignore for now, in hopes that @gabi-250 can help me
figure it out.
This closes #808. There are several changes I want to make before
we merge, however. They are marked with TODO DALEK.
