Examples

use plume_arkworks::{
    PlumeSignaturePublic, PlumeSignaturePrivate, PlumeVersion, sign, SWCurveConfig, CurveGroup,
    secp256k1::{Fr, Config},
    rand::rngs::OsRng
};

    let message_the = b"ZK nullifier signature";
    // you should get the real secret key you for signing
    let sk = <Fr as ark_ff::UniformRand>::rand(&mut OsRng);

    let sig = sign(
        &mut OsRng, (
            &(Config::GENERATOR * sk).into_affine(),
            &sk,
        ), message_the.as_slice(), PlumeVersion::V1
    );
