mrwulf f17cbd1a19 Aeneas-compat: single-call sha512_hash3 oracle (sha2-0.10 stack) 
This fork's sha2-0.10 Sha512 type alias cannot be declared opaque by the
extractor (generic-array expansion), so the three stateful hasher wrappers
collapse into one monomorphic sha512_hash3(r, a, m) -> [u8; 64] whose
signature carries no foreign types. Semantically Sha512 over r || a || m —
exactly the H(R || A || M) the verification equation hashes. Extraction
builds with --no-default-features (the no-std From<InternalError> branch
uses Error::new, avoiding the boxed dyn-Error source path).

Dalek elliptic curve cryptography

This repo contains pure-Rust crates for elliptic curve cryptography:

Crate Description Crates.io Docs CI
curve25519‑dalek A library for arithmetic over the Curve25519 and Ristretto elliptic curves and their associated scalars. CI
ed25519‑dalek An implementation of the EdDSA digital signature scheme over Curve25519. CI
x25519‑dalek An implementation of elliptic curve Diffie-Hellman key exchange over Curve25519. CI

There is also the curve25519-dalek-derive crate, which is just a helper crate with some macros that make curve25519-dalek easier to write.
