Crate commonware_cryptography

Generate keys, sign arbitrary messages, and deterministically verify signatures.

Status

commonware-cryptography is ALPHA software and is not yet recommended for production use. Developers should expect breaking changes and occasional instability.

Modules

bls12381

Distributed Key Generation (DKG), Resharing, Signatures, and Threshold Signatures over the BLS12-381 curve.

ed25519

Ed25519 implementation of the Scheme trait.

secp256r1

Secp256r1 implementation of the Scheme trait.

sha256

SHA-256 implementation of the Hasher trait.

Traits

BatchScheme

Implementation that can indicate whether all Signatures are correct or that some Signature is incorrect.

Committable

An object that shares a (commitment) Digest with other, related values.

Digest

Specializes the commonware_utils::Array trait with the Copy trait for cryptographic digests (which should be cheap to clone).

Digestible

An object that can be uniquely represented as a Digest.

Hasher

Interface that commonware crates rely on for hashing.

Scheme

Implementation that can both sign and verify messages.

Signer

Implementation that can sign a message with a PrivateKey.

Specification

Any implementation of a cryptographic primitive must specify a PublicKey and Signature.

Verifier

Implementation that can verify that a PublicKey produced a valid Signature.
