pub struct KeysManager { /* private fields */ }

Expand description

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!

Implementations

source

impl KeysManager

source

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

source

impl KeysInterface for KeysManager

source

fn get_node_secret(&self) -> SecretKey

Get node secret key (aka node_id or network_key)

source

fn get_destination_script(&self) -> Script

Get destination redeemScript to encumber static protocol exit points.
