Struct iop_keyvault::Bip32PublicNode

pub struct Bip32PublicNode<C: KeyDerivationCrypto + 'static> { /* fields omitted */ }

In BIP-0032 a neutered extended private key is an extended public key. This struct represents such an extended public key in a given subtree. It is able to do normal (public) derivation, signature verification, creating and validating key identifiers

Implementations

impl<C: KeyDerivationCrypto + 'static> Bip32PublicNode<C>

pub fn new(
    path: Path,
    xpk: <C as KeyDerivationCrypto>::ExtendedPublicKey,
    subtree: &'static dyn Subtree<Suite = C>
) -> Self

Backdoor for advanced or fringe non-standard use-cases. Use [Bip32.master] instead for normal use-cases.

pub fn path(&self) -> &Path

Accessor for the BIP32 path of this node

pub fn xpk(&self) -> &<C as KeyDerivationCrypto>::ExtendedPublicKey

Accessor for the extended public key of this node

pub fn subtree(&self) -> &'static dyn Subtree<Suite = C>

Accessor for the subtree of this node

pub fn derive_normal(&self, idx: i32) -> Result<Bip32PublicNode<C>>

Create a new node with normal (public) derivation with the given index.

pub fn public_key(&self) -> C::PublicKey

Creates the public key that belongs to this node for verifying authentications done by the private key.

pub fn key_id(&self) -> C::KeyId

Creates the key identifier for the public key. This is an extra layer of security for single-use keys, so the revealing of the public key can be delayed to the point when the authenticated action (spending some coin or revoking access) makes the public key irrelevant after the action is successful.

impl Bip32PublicNode<Secp256k1>

pub fn from_xpub(
    path: Path,
    xpub: impl AsRef<str>,
    network: &'static dyn Network<Suite = Secp256k1>
) -> Result<Bip32PublicNode<Secp256k1>>

Recreates the BIP32 public node from its parts

pub fn to_xpub(
    &self,
    network: &'static dyn Network<Suite = Secp256k1>
) -> String

Returns the extended public key in the BIP32 readable format with the version bytes of the network.

pub fn to_p2pkh_addr(
    &self,
    network: &'static dyn Network<Suite = Secp256k1>
) -> String

Returns the P2PKH address that belongs key with the version byte of the network.

Trait Implementations

impl<C: Clone + KeyDerivationCrypto + 'static> Clone for Bip32PublicNode<C>

fn clone(&self) -> Bip32PublicNode<C>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<C: KeyDerivationCrypto + 'static> Debug for Bip32PublicNode<C>

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

Formats the value using the given formatter.
