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

blake3

BLAKE3 implementation of the Hasher trait.

bloomfilter

An implementation of a Bloom Filter.

bls12381

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

certificate

Cryptographic primitives for generating and verifying certificates.

ed25519

Ed25519 implementation of the crate::Verifier and crate::Signer traits.

handshake

This module provides an authenticated key exchange protocol, or handshake.

lthash

A homomorphic hash function that enables efficient incremental updates.

secp256r1

Secp256r1 implementation of the crate::Verifier and crate::Signer traits.

sha256

SHA-256 implementation of the Hasher trait.

transcript

This module provides a Transcript abstraction.

Macros

impl_certificate_bls12381_multisig

Generates a BLS12-381 multisig signing scheme wrapper for a specific protocol.

impl_certificate_bls12381_threshold

Generates a BLS12-381 threshold signing scheme wrapper for a specific protocol.

impl_certificate_ed25519

Generates an Ed25519 signing scheme wrapper for a specific protocol.

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.

PublicKey

A PublicKey, able to verify Signatures.

Recoverable

An extension of Signature that supports public key recovery.

Signature

A Signature over a message.

Signer

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

Verifier

Verifies Signatures over messages.
