Struct jubjub_schnorr::PublicKey
source · pub struct PublicKey(/* private fields */);
Expand description
Structure representing a PublicKey
, consisting of a JubJubExtended
point on the JubJub curve. This public key allows for the verification of
signatures created with its corresponding secret key without revealing the
secret key itself.
§Examples
Generate a PublicKey
from a SecretKey
:
use jubjub_schnorr::{SecretKey, PublicKey};
use dusk_bls12_381::BlsScalar;
use rand::rngs::StdRng;
use rand::SeedableRng;
let mut rng = StdRng::seed_from_u64(12345);
let sk = SecretKey::random(&mut rng);
let pk = PublicKey::from(&sk);
Implementations§
source§impl PublicKey
impl PublicKey
sourcepub fn verify(&self, sig: &Signature, message: BlsScalar) -> bool
pub fn verify(&self, sig: &Signature, message: BlsScalar) -> bool
Verifies that the given Schnorr Signature
is valid.
This function computes a challenge hash c
using the stored R
point
and the provided message, then performs the verification by checking
that:
u * G + c * PK == R
§Parameters
§Returns
A boolean value indicating the validity of the Schnorr Signature
.
sourcepub const fn from_raw_unchecked(key: JubJubExtended) -> Self
pub const fn from_raw_unchecked(key: JubJubExtended) -> Self
Create a PublicKey
from its internal parts.
The public keys are generated from a bijective function that takes a secret keys domain. If keys are generated directly from curve points, there is no guarantee a secret key exists - in fact, the discrete logarithm property will guarantee the secret key cannot be extracted from this public key.
If you opt to generate the keys manually, be sure you have its secret counterpart - otherwise this key will be of no use.
