Examples

use plume_arkworks::{PlumeSignature, PlumeVersion, SWCurveConfig};
use rand_core::OsRng;

    let message_the = b"ZK nullifier signature";
    let sk = PlumeSignature::keygen(&mut OsRng);

    let sig = PlumeSignature::sign(
        &mut OsRng, (&sk.0, &sk.1), message_the.as_slice(), PlumeVersion::V1
    );

    assert!(
        sig.unwrap()
        .verify_non_zk(
            &plume_arkworks::Parameters{
                g_point: plume_arkworks::secp256k1::Config::GENERATOR
            },
            &sk.0,
            message_the,
            PlumeVersion::V1
        ).unwrap()
    );
