Struct ExtendedPublicKey 

pub struct ExtendedPublicKey { /* private fields */ }

Extended public key (BIP32).

Can derive child public keys for non-hardened paths only.

Implementations

impl ExtendedPublicKey

pub fn derive_child(&self, index: u32) -> Result<Self, HdError>

Derive child public key (normal derivation only).

Returns error for hardened derivation (index >= 0x80000000).

pub fn derive_path(&self, path: &DerivationPath) -> Result<Self, HdError>

Derive key at derivation path (normal derivation only).

pub fn public_key(&self) -> PublicKey

Get the underlying public key.

pub fn fingerprint(&self) -> [u8; 4]

Get fingerprint (first 4 bytes of HASH160 of public key).

pub fn depth(&self) -> u8

Get depth in derivation tree.

pub fn chain_code(&self) -> &[u8; 32]

Get chain code.

pub fn network(&self) -> Network

Get network.

pub fn to_xpub(&self) -> String

Serialize to xpub string (Base58Check).

pub fn from_xpub(xpub: &str) -> Result<Self, HdError>

Parse from xpub string (Base58Check).
