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

BatchVerifier

Verifies whether all Signatures are correct or that some Signature is incorrect.

Committable

An object that can produce a commitment of itself.

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.

PrivateKey

A Signer that can be serialized/deserialized.

PrivateKeyExt

A PrivateKey that can be generated from a seed or RNG.

PublicKey

A PublicKey, able to verify Signatures.

Signature

A Signature over a message.

Signer

Produces Signatures over messages that can be verified with a corresponding PublicKey.

Verifier

Verifies Signatures over messages.
