Struct dusk_schnorr::Signature
source · pub struct Signature { /* private fields */ }
Expand description
An Schnorr signature, produced by signing a message with a SecretKey
.
Fields
u
: AJubJubScalar
R
: AJubJubExtended
point
Example
use dusk_bls12_381::BlsScalar;
use dusk_schnorr::{PublicKey, SecretKey, Signature};
use rand::rngs::StdRng;
use rand::SeedableRng;
use ff::Field;
let mut rng = StdRng::seed_from_u64(1234u64);
let sk = SecretKey::random(&mut rng);
let message = BlsScalar::random(&mut rng);
let pk = PublicKey::from(&sk);
// Sign the message
let signature = sk.sign(&mut rng, message);
// Verify the signature
assert!(pk.verify(&signature, message));
Implementations§
source§impl Signature
impl Signature
sourcepub fn u(&self) -> &JubJubScalar
pub fn u(&self) -> &JubJubScalar
Exposes the u
scalar of the Schnorr signature.
sourcepub fn R(&self) -> &JubJubExtended
pub fn R(&self) -> &JubJubExtended
Exposes the R
point of the Schnorr signature.
sourcepub fn append(&self, composer: &mut Composer) -> (Witness, WitnessPoint)
pub fn append(&self, composer: &mut Composer) -> (Witness, WitnessPoint)
Appends the single key as a witness to the circuit composed by the
Composer
.
Feature
Only available with the “alloc” feature enabled.
Parameters
composer
: Mutable reference to the PlonkComposer
.
Returns
Returns a tuple (Witness, WitnessPoint)
containing converted u
and
R
fields.
