Crate commonware_cryptography 

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

Randomness

Cryptographic operations that accept an RNG require a cryptographically secure and unpredictable source unless documented otherwise. A weak or predictable RNG may compromise security.

Status

Stability varies by primitive. See README for details.

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.

Structs

BatchEntry

A borrowed view of one signature and the message it authenticates.

Digested

A shared value paired with its Digest.

Traits

BatchVerifier

A PublicKey that supports batch verification of Signatures.

Cipher

Authenticated encryption of an ordered sequence of messages.

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.
