pub struct SecpExtPrivateKey { /* private fields */ }

Implementation of Secp256k1::ExtendedPrivateKey

Implementations

impl SecpExtPrivateKey

pub fn to_xprv(&self, version: &[u8; 4]) -> String

Serializes the extended private key according to the format defined in BIP32

pub fn from_xprv(xprv: &str, prefix: &[u8; 4]) -> Result<Self>

Deserializes the extended private key from the format defined in BIP32

Trait Implementations

impl Clone for SecpExtPrivateKey

fn clone(&self) -> SecpExtPrivateKey

Returns a copy of the value.

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

Performs copy-assignment from source.

impl ExtendedPrivateKey<Secp256k1> for SecpExtPrivateKey

fn derive_normal_child(&self, idx: i32) -> Result<SecpExtPrivateKey>

Normal derivation allows the neutered extended public key to calculate child extended public keys without revealing any private keys.

fn derive_hardened_child(&self, idx: i32) -> Result<SecpExtPrivateKey>

Hardened derivation makes it impossible to the neutered extended public key to calculate children. It uses a different derivation algorithm.

fn neuter(&self) -> SecpExtPublicKey

Neutering an extended private key gives an extended public key that contains the private key neutered, plus the chain code. It is useless to reveal the chain code when hardened derivation is used.

fn private_key(&self) -> SecpPrivateKey

Throws away the chain code and gives back only the private key from the extended private key.
