Implementations§

source§

impl DerivedXPriv

source

pub fn sign_digest_recoverable<D>( &self, digest: D ) -> Result<(Signature, RecoveryId), Error>where D: FixedOutput<OutputSize = U32> + Clone + Default + Reset + Update + HashMarker,

Sign the given message digest, returning a signature and recovery ID. See ECDSA docs here

source§

impl DerivedXPriv

source

pub const fn new(xpriv: XPriv, derivation: KeyDerivation) -> Self

Instantiate a derived XPub from the XPub and derivatin. This usually should not be called directly. Prefer deriving keys from parents.

source

pub fn is_private_ancestor_of( &self, other: &DerivedXPub ) -> Result<bool, Bip32Error>

Check if this XPriv is the private ancestor of some other derived key. To check ancestry of another private key, derive its public key first

source

pub fn root_node( hmac_key: &[u8], data: &[u8], hint: Option<Hint> ) -> Result<DerivedXPriv, Bip32Error>

Generate a customized root node using the stati

source

pub fn root_from_seed( data: &[u8], hint: Option<Hint> ) -> Result<DerivedXPriv, Bip32Error>

Generate a root node from some seed data. Uses the BIP32-standard hmac key.

Important:

Use a seed of AT LEAST 128 bits.

source

pub fn custom_root_node( hmac_key: &[u8], data: &[u8], hint: Option<Hint> ) -> Result<DerivedXPriv, Bip32Error>

Instantiate a root node using a custom HMAC key.

source

pub fn custom_root_from_seed( data: &[u8], hint: Option<Hint> ) -> Result<DerivedXPriv, Bip32Error>

Generate a root node from some seed data. Uses the BIP32-standard hmac key.

Important:

Use a seed of AT LEAST 128 bits.

source

pub fn verify_key(&self) -> DerivedXPub

Derive the corresponding xpub
