Struct HtlcBasepoint

pub struct HtlcBasepoint(pub PublicKey);

Base key used in conjunction with a per_commitment_point to generate an HtlcKey.

HTLC keys are used to ensure only the recipient of an HTLC can claim it on-chain with the HTLC preimage and that only the sender of an HTLC can claim it on-chain after it has timed out. Thus, both channel counterparties’ HTLC keys will appears in each HTLC output’s script.

Implementations

impl HtlcBasepoint

pub fn to_public_key(&self) -> PublicKey

Get inner Public Key

pub fn derive_add_tweak(&self, per_commitment_point: &PublicKey) -> Hash

Derives the “tweak” used in calculate HtlcKey::from_basepoint.

HtlcKey::from_basepoint calculates a private key as: privkey = basepoint_secret + SHA256(per_commitment_point || basepoint)

This calculates the hash part in the tweak derivation process, which is used to ensure that each key is unique and cannot be guessed by an external party.

Trait Implementations

impl Clone for HtlcBasepoint

fn clone(&self) -> HtlcBasepoint

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for HtlcBasepoint

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

Formats the value using the given formatter.

impl From<PublicKey> for HtlcBasepoint

fn from(value: PublicKey) -> HtlcBasepoint

Converts to this type from the input type.

impl Hash for HtlcBasepoint

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for HtlcBasepoint

fn eq(&self, other: &HtlcBasepoint) -> 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 Readable for HtlcBasepoint

fn read<R>(r: &mut R) -> Result<HtlcBasepoint, DecodeError>

where R: Read,

Reads a Self in from the given Read.

impl Writeable for HtlcBasepoint

fn write<W>(&self, w: &mut W) -> Result<(), Error>

where W: Writer,

Writes self out to the given Writer.

fn encode(&self) -> Vec<u8>

Writes self out to a Vec<u8>.

fn serialized_length(&self) -> usize

Gets the length of this object after it has been serialized. This can be overridden to optimize cases where we prepend an object with its length.
