Struct InMemorySigner 

pub struct InMemorySigner {
    pub funding_key: Privkey,
    pub tlc_base_key: Privkey,
    pub musig2_base_nonce: Privkey,
    pub commitment_seed: [u8; 32],
}

A simple implementation of a channel signer that keeps the private keys in memory.

This implementation performs no policy checks and is insufficient by itself as a secure external signer.

Fields

funding_key: Privkey

Holder secret key in the 2-of-2 multisig script of a channel.

tlc_base_key: Privkey

Holder HTLC secret key used in commitment transaction HTLC outputs.

musig2_base_nonce: Privkey

SecNonce used to generate valid signature in musig.

commitment_seed: [u8; 32]

Seed to derive above keys (per commitment).

Implementations

impl InMemorySigner

pub fn generate_from_seed(params: &[u8]) -> InMemorySigner

Generate an InMemorySigner from a seed.

pub fn get_base_public_keys(&self) -> ChannelBasePublicKeys

Get the base public keys for this signer.

pub fn get_commitment_point(&self, commitment_number: u64) -> Pubkey

Returns the commitment point for the given commitment number.

The commitment point is the public key derived from the commitment seed and the commitment number. It is used to derive the pubkeys used in TLC (htlc and revocation outputs).

pub fn get_commitment_secret(&self, commitment_number: u64) -> [u8; 32]

Returns the commitment secret for the given commitment number.

pub fn derive_tlc_key(&self, new_commitment_number: u64) -> Privkey

Derive the TLC key for the given commitment number.

pub fn derive_musig2_nonce( &self, commitment_number: u64, context: Musig2Context, ) -> SecNonce

Derive a musig2 nonce for the given commitment number and context.

Trait Implementations

impl Clone for InMemorySigner

fn clone(&self) -> InMemorySigner

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for InMemorySigner

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for InMemorySigner

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for InMemorySigner

fn eq(&self, other: &InMemorySigner) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for InMemorySigner

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
