Trait Implementations

impl NodeSigner for DynKeysInterface

fn get_node_id(&self, recipient: Recipient) -> Result<PublicKey, ()>

Get node id based on the provided Recipient.

fn sign_gossip_message( &self, msg: UnsignedGossipMessage<'_>, ) -> Result<Signature, ()>

Sign a gossip message.

fn ecdh( &self, recipient: Recipient, other_key: &PublicKey, tweak: Option<&Scalar>, ) -> Result<SharedSecret, ()>

Gets the ECDH shared secret of our node secret and other_key, multiplying by tweak if one is provided. Note that this tweak can be applied to other_key instead of our node secret, though this is less efficient.

fn sign_invoice( &self, invoice: &RawBolt11Invoice, recipient: Recipient, ) -> Result<RecoverableSignature, ()>

Sign an invoice.

fn sign_bolt12_invoice( &self, invoice: &UnsignedBolt12Invoice, ) -> Result<Signature, ()>

Signs the TaggedHash of a BOLT 12 invoice.

fn get_expanded_key(&self) -> ExpandedKey

Get the ExpandedKey which provides cryptographic material for various Lightning Network operations.

fn get_peer_storage_key(&self) -> PeerStorageKey

Defines a method to derive a 32-byte encryption key for peer storage.

fn get_receive_auth_key(&self) -> ReceiveAuthKey

Returns the ReceiveAuthKey used to authenticate incoming BlindedMessagePath contexts.

fn sign_message(&self, msg: &[u8]) -> Result<String, ()>

Sign an arbitrary message with the node’s secret key.

impl SignerProvider for DynKeysInterface

type EcdsaSigner = DynSigner

A type which implements EcdsaChannelSigner which will be returned by Self::derive_channel_signer.

fn get_destination_script(&self, buf: [u8; 32]) -> Result<ScriptBuf, ()>

Get a script pubkey which we send funds to when claiming on-chain contestable outputs.

fn get_shutdown_scriptpubkey(&self) -> Result<ShutdownScript, ()>

Get a script pubkey which we will send funds to when closing a channel.

fn generate_channel_keys_id( &self, _inbound: bool, _user_channel_id: u128, ) -> [u8; 32]

Generates a unique channel_keys_id that can be used to obtain a Self::EcdsaSigner through SignerProvider::derive_channel_signer. The user_channel_id is provided to allow implementations of SignerProvider to maintain a mapping between itself and the generated channel_keys_id.

fn derive_channel_signer(&self, _channel_keys_id: [u8; 32]) -> Self::EcdsaSigner

Derives the private key material backing a Signer.

impl SpendableKeysInterface for DynKeysInterface

fn spend_spendable_outputs( &self, descriptors: &[&SpendableOutputDescriptor], outputs: Vec<TxOut>, change_destination_script: ScriptBuf, feerate_sat_per_1000_weight: u32, secp_ctx: &Secp256k1<All>, ) -> Result<Transaction>

fn get_sweep_address(&self) -> Address

Swept funds from closed channels are sent here This is implemented by setting the change destination to spend_spendable_outputs to this address.
