Implementations§
source§impl ExtendedPubKey
impl ExtendedPubKey
sourcepub fn from_priv<C: Signing>(
secp: &Secp256k1<C>,
sk: &ExtendedPrivKey
) -> ExtendedPubKey
pub fn from_priv<C: Signing>( secp: &Secp256k1<C>, sk: &ExtendedPrivKey ) -> ExtendedPubKey
Derives a public key from a private key
sourcepub fn to_pub(self) -> PublicKey
pub fn to_pub(self) -> PublicKey
Constructs ECDSA compressed public key matching internal public key representation.
sourcepub fn to_x_only_pub(self) -> XOnlyPublicKey
pub fn to_x_only_pub(self) -> XOnlyPublicKey
Constructs BIP340 x-only public key for BIP-340 signatures and Taproot use matching the internal public key representation.
sourcepub fn derive_pub<C: Verification, P: AsRef<[ChildNumber]>>(
&self,
secp: &Secp256k1<C>,
path: &P
) -> Result<ExtendedPubKey, Error>
pub fn derive_pub<C: Verification, P: AsRef<[ChildNumber]>>( &self, secp: &Secp256k1<C>, path: &P ) -> Result<ExtendedPubKey, Error>
Attempts to derive an extended public key from a path.
The path
argument can be any type implementing AsRef<ChildNumber>
, such as DerivationPath
, for instance.
sourcepub fn ckd_pub_tweak(
&self,
i: ChildNumber
) -> Result<(SecretKey, ChainCode), Error>
pub fn ckd_pub_tweak( &self, i: ChildNumber ) -> Result<(SecretKey, ChainCode), Error>
Compute the scalar tweak added to this key to get a child key
sourcepub fn ckd_pub<C: Verification>(
&self,
secp: &Secp256k1<C>,
i: ChildNumber
) -> Result<ExtendedPubKey, Error>
pub fn ckd_pub<C: Verification>( &self, secp: &Secp256k1<C>, i: ChildNumber ) -> Result<ExtendedPubKey, Error>
Public->Public child key derivation
sourcepub fn decode(data: &[u8]) -> Result<ExtendedPubKey, Error>
pub fn decode(data: &[u8]) -> Result<ExtendedPubKey, Error>
Decoding extended public key from binary data according to BIP 32
sourcepub fn identifier(&self) -> XpubIdentifier
pub fn identifier(&self) -> XpubIdentifier
Returns the HASH160 of the chaincode
sourcepub fn fingerprint(&self) -> Fingerprint
pub fn fingerprint(&self) -> Fingerprint
Returns the first four bytes of the identifier
