Crate plume_rustcrypto 

A library for generating and verifying PLUME signatures.

See https://blog.aayushg.com/nullifier for more information.

Examples

If you want more control or to be more generic on traits use PlumeSigner from randomizedsigner

use plume_rustcrypto::{PlumeSignature, SecretKey};
use rand_core::OsRng;
    let sig_v1 = PlumeSignature::sign_v1(
        &sk, b"ZK nullifier signature", &mut OsRng
    );
    assert!(sig_v1.verify());

    let sig_v2 = PlumeSignature::sign_v2(
        &sk, b"ZK nullifier signature", &mut OsRng
    );
    assert!(sig_v2.verify());

Modules

randomizedsigner

Provides the RandomizedSigner trait implementation over PlumeSignature.

Structs

AffinePoint

Exports types from the k256 crate:

PlumeSignature

Struct holding signature data for a PLUME signature.

PlumeSignatureV1Fields

Nested struct holding additional signature data used in variant 1 of the protocol.

Constants

DST

The domain separation tag used for hashing to the secp256k1 curve

Traits

CryptoRngCore

Re-exports the CryptoRngCore trait from the rand_core crate. This allows it to be used from the current module. An extension trait that is automatically implemented for any type implementing RngCore and CryptoRng.

Deserialize

Provides the ability to serialize and deserialize data using the Serde library. The Serialize and Deserialize traits from the Serde library are re-exported for convenience. A data structure that can be deserialized from any data format supported by Serde.

Serialize

Provides the ability to serialize and deserialize data using the Serde library. The Serialize and Deserialize traits from the Serde library are re-exported for convenience. A data structure that can be serialized into any data format supported by Serde.

Type Aliases

NonZeroScalar

Exports types from the k256 crate:

SecretKey

Exports types from the k256 crate:
