Implementations

impl ExtendedPrivKey[−]

pub fn new_master(
    network: Network,
    seed: &[u8]
) -> Result<ExtendedPrivKey, Error>[−]

Construct a new master key from a seed value

pub fn derive_priv<C: Signing, P: AsRef<[ChildNumber]>>(
    &self,
    secp: &Secp256k1<C>,
    path: &P
) -> Result<ExtendedPrivKey, Error>[−]

Attempts to derive an extended private key from a path.

The path argument can be both of type DerivationPath or Vec<ChildNumber>.

pub fn ckd_priv<C: Signing>(
    &self,
    secp: &Secp256k1<C>,
    i: ChildNumber
) -> Result<ExtendedPrivKey, Error>[−]

Private->Private child key derivation

pub fn decode(data: &[u8]) -> Result<ExtendedPrivKey, Error>[−]

Decoding extended private key from binary data according to BIP 32

pub fn encode(&self) -> [u8; 78][−]

Extended private key binary encoding according to BIP 32

pub fn identifier<C: Signing>(&self, secp: &Secp256k1<C>) -> XpubIdentifier[−]

Returns the HASH160 of the public key belonging to the xpriv

pub fn fingerprint<C: Signing>(&self, secp: &Secp256k1<C>) -> Fingerprint[−]

Returns the first four bytes of the identifier
