Struct lightning::chain::keysinterface::KeysManager

pub struct KeysManager { /* fields omitted */ }

Simple KeysInterface implementor that takes a 32-byte seed for use as a BIP 32 extended key and derives keys from that.

Your node_id is seed/0' ChannelMonitor closes may use seed/1' Cooperative closes may use seed/2' The two close keys may be needed to claim on-chain funds!

Methods

impl KeysManager

pub fn new(     seed: &[u8; 32],     network: Network,     logger: Arc<dyn Logger> ) -> KeysManager

Constructs a KeysManager from a 32-byte seed. If the seed is in some way biased (eg your RNG is busted) this may panic.

Trait Implementations

impl KeysInterface for KeysManager

fn get_node_secret(&self) -> SecretKey

Get node secret key (aka node_id or network_key)

fn get_destination_script(&self) -> Script

Get destination redeemScript to encumber static protocol exit points.

fn get_shutdown_pubkey(&self) -> PublicKey

Get shutdown_pubkey to use as PublicKey at channel closure

fn get_channel_keys(&self, _inbound: bool) -> ChannelKeys

Get a new set of ChannelKeys for per-channel secrets. These MUST be unique even if you restarted with some stale data!

fn get_session_key(&self) -> SecretKey

Get a secret for construting an onion packet

fn get_channel_id(&self) -> [u8; 32]

Get a unique temporary channel id. Channels will be referred to by this until the funding transaction is created, at which point they will use the outpoint in the funding transaction.
