tor-(hs|ll)crypto: deftly derive ConstantTimeEq

2025-09-23T08:25:49Z

This is my initial attempt at deriving ConstantTimeEq and PartialEq. This includes the previously missed HsSvcNtorKeypair and HsClientDescEncKeypair types. In tor-llcrypto, a few implementations still had to be done by hand, and some types which previously derived normal PartialEq now derive it with ConstantTimeEq. I could not figure out how to properly set up the macros such that they could be used both in the current crate and in others, so for the moment they are duplicated. Just so I can get feedback. Ideally, this will be replaced with a better solution before merge. Signed-off-by: hashcatHitman <3924-hashcatHitman@gitlab.torproject.org>

tor-llcrypto: as_bytes on curve25519::StaticSecret

2025-09-16T20:52:25Z

Exposed `as_bytes` on `curve25519::StaticSecret`, allowing a shared reference to the secret bytes rather than needing to copy them. Signed-off-by: hashcatHitman <3924-hashcatHitman@gitlab.torproject.org>

Switch Cargo.toml files to edition 2024.

2025-08-07T15:28:36Z

First, run ``` git grep -l "^edition =" | xargs perl -i -pe 's/^edition *=.*/edition = "2024"/;' ``` Second, manually verify that all Cargo.toml files have changed, and nothing else has changed. Third, run cargo fmt again.

llcrypto: add an rng compatibility shim for dalek-crypto

2025-03-18T16:09:44Z

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.

2025-03-17T18:40:17Z

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.

Clarify and downgrade TODO about ReusableSecret.

Convert to the latest versions of dalek-cryptography

2023-11-29T15:34:58Z

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.
