Struct ed25519_bip32::XPrv

pub struct XPrv(_);

HDWallet extended private key

Effectively this is ed25519 extended secret key (64 bytes) followed by a chain code (32 bytes)

Methods

impl XPrv

pub fn normalize_bytes(bytes: [u8; 96]) -> Self

takes the given raw bytes and perform some modifications to normalize to a valid XPrv.

pub fn from_nonextended(bytes: [u8; 32], chain_code: [u8; 32]) -> Self

Takes a non-extended ed25519 key and hash through SHA512 it in the same way the standard Ed25519 signature system make extended key, but also clean the 3rd highest bit of the key as described in the paper

pub fn from_bytes_verified(bytes: [u8; 96]) -> Result<Self, PrivateKeyError>

Create a XPrv by taking ownership of the given array

This function may returns an error if it does not have the expected format.

pub fn from_slice_verified(bytes: &[u8]) -> Result<Self, PrivateKeyError>

pub fn public(&self) -> XPub

Get the associated XPub

pub fn sign<T>(&self, message: &[u8]) -> Signature<T>

sign the given message with the XPrv.

pub fn verify<T>(&self, message: &[u8], signature: &Signature<T>) -> bool

verify a given signature

pub fn derive(&self, scheme: DerivationScheme, index: DerivationIndex) -> Self

pub fn get_extended(&self, out: &mut [u8; 64])
