Struct wownero::cryptonote::onetime_key::KeyGenerator

pub struct KeyGenerator {
    pub spend: PublicKey,
    pub rv: PublicKey,
}

Helper to generate onetime public keys (ephemeral keys) used in transactions.

Fields

spend: PublicKey

Spend public key S.

rv: PublicKey

Intermediate key v*8*R or r*8*V used during the generation process.

Implementations

impl KeyGenerator

pub fn from_random(
    view: PublicKey,
    spend: PublicKey,
    random: PrivateKey
) -> Self

Construct a onetime key generator from public keys and secret random, this is used to generate onetime keys for output indexes from an address when sending funds.

pub fn from_key(keys: &ViewPair, random: PublicKey) -> Self

Construct a onetime key generator from private keys and public random (tx pubkey), this is used to scan if some outputs contains onetime keys owned by the view pair.

pub fn one_time_key(&self, index: usize) -> PublicKey

Compute the onetime public key P = Hn(r*8*V || n)*G + S for the indexed output n.

pub fn check(&self, index: usize, key: PublicKey) -> bool

Check if key P is equal to indexed key P', if true the output is own by the address, used when scanning transaction outputs, if true the onetime key is related to the keys.

pub fn get_rvn_scalar(&self, index: usize) -> PrivateKey

Computes Hn(v*8*R || n) and interpret it as a scalar.
