dkls23-core

Curve-generic core implementation of the DKLs23 Threshold ECDSA protocol.

This crate provides the cryptographic primitives and protocol logic for:

• Distributed Key Generation (DKG) — generate key shares without a trusted dealer
• Threshold Signing — produce ECDSA signatures with a subset of parties
• Key Refresh — rotate key shares without changing the public key
• BIP-32 Derivation — derive child keys from a master key share

Usage

This is the curve-generic core — most users should depend on a curve-specific crate instead:

• dkls23-secp256k1 — for Ethereum, Bitcoin, Cosmos, TRON
• dkls23-secp256r1 — for NEO3, Sui

Use dkls23-core directly only if you need to implement a custom curve via the DklsCurve trait.

dkls23-core = "0.5"

API Levels

• High-level: DkgSession and SignSession manage protocol state automatically
• Low-level: phase1–phase4 functions and keep-state types for advanced resumable/stateless orchestration

For session orchestration, transport, and resumable flows, see libtss.
