Struct monero::cryptonote::onetime_key::SubKeyChecker

pub struct SubKeyChecker<'a> {
    pub table: HashMap<PublicKey, Index>,
    pub keys: &'a ViewPair,
}

Helper to check if a onetime sub-address public key is related to a view pair.

Generate a table of sub-keys from a view pair given a major range and a minor range. These precomputed keys are used to check if an output is owned by the root view pair.

Fields

table: HashMap<PublicKey, Index>

Table of public spend keys and their corresponding indexes.

keys: &'a ViewPair

The root view pair (v, S).

Implementations

impl<'a> SubKeyChecker<'a>

pub fn new(keys: &'a ViewPair, major: Range<u32>, minor: Range<u32>) -> Self

Generate the table of sub spend keys K(S) \in major x minor from a view pair mapped to their Sub-address indexes.

pub fn check(
    &self,
    index: usize,
    key: &PublicKey,
    tx_pubkey: &PublicKey
) -> Option<&Index>

Check if an output public key with its associated random tx public key at index i is in the table, if found then the output is own by the view pair, otherwise the output might be own by someone else, or the table migth be too small.

pub fn check_with_key_generator(
    &self,
    keygen: KeyGenerator,
    index: usize,
    key: &PublicKey
) -> Option<&Index>

Same as check but uses a pre-generated KeyGenerator
