Struct wownero::cryptonote::onetime_key::KeyRecoverer

pub struct KeyRecoverer<'a> {
    pub keys: &'a KeyPair,
    pub checker: KeyGenerator,
}

Helper to compute onetime private keys.

Fields

keys: &'a KeyPair

Private key pair (v, s).

checker: KeyGenerator

Key generator used to check and generate intermediate values.

Implementations

impl<'a> KeyRecoverer<'a>

pub fn new(keys: &'a KeyPair, tx_pubkey: PublicKey) -> Self

Construct a onetime key generator from private keys, this is used when scanning transaction outputs to recover private onetime keys.

pub fn recover(&self, oindex: usize, aindex: Index) -> PrivateKey

Recover the onetime private key p at address index i (major, minor indexes) and output index n such as:

p = { Hn(v*8*R || n) + s                  i == 0
    { Hn(v*8*R || n) + s + Hn(v || i)     otherwise

See sub-address key derivation for more details on address index handling.
