Trait bip32::PrivateKey

pub trait PrivateKey: Sized {
    type PublicKey: PublicKey;

    // Required methods
    fn from_bytes(bytes: &PrivateKeyBytes) -> Result<Self>;
    fn to_bytes(&self) -> PrivateKeyBytes;
    fn derive_child(&self, other: PrivateKeyBytes) -> Result<Self>;
    fn public_key(&self) -> Self::PublicKey;
}

Trait for key types which can be derived using BIP32.

Required Associated Types

type PublicKey: PublicKey

Public key type which corresponds to this private key.

Required Methods

fn from_bytes(bytes: &PrivateKeyBytes) -> Result<Self>

Initialize this key from bytes.

fn to_bytes(&self) -> PrivateKeyBytes

Serialize this key as bytes.

fn derive_child(&self, other: PrivateKeyBytes) -> Result<Self>

Derive a child key from a parent key and the a provided tweak value, i.e. where other is referred to as “I sub L” in BIP32 and sourced from the left half of the HMAC-SHA-512 output.

fn public_key(&self) -> Self::PublicKey

Get the Self::PublicKey that corresponds to this private key.
