Implementations§
§impl Xpub
impl Xpub
pub fn from_priv<C>(secp: &Secp256k1<C>, sk: &Xpriv) -> Xpubwhere
C: Signing,
pub fn from_priv<C>(secp: &Secp256k1<C>, sk: &Xpriv) -> Xpubwhere
C: Signing,
Derives a public key from a private key
pub fn to_pub(self) -> CompressedPublicKey
pub fn to_pub(self) -> CompressedPublicKey
Constructs ECDSA compressed public key matching internal public key representation.
pub 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.
pub fn derive_pub<C, P>(
&self,
secp: &Secp256k1<C>,
path: &P
) -> Result<Xpub, Error>
pub fn derive_pub<C, P>( &self, secp: &Secp256k1<C>, path: &P ) -> Result<Xpub, 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.

&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
pub fn ckd_pub<C>(
&self,
secp: &Secp256k1<C>,
i: ChildNumber
) -> Result<Xpub, Error>where
C: Verification,
pub fn ckd_pub<C>(
&self,
secp: &Secp256k1<C>,
i: ChildNumber
) -> Result<Xpub, Error>where
C: Verification,
Public->Public child key derivation
pub fn decode(data: &[u8]) -> Result<Xpub, Error>
pub fn decode(data: &[u8]) -> Result<Xpub, Error>
Decoding extended public key from binary data according to BIP 32
pub fn identifier(&self) -> XKeyIdentifier
pub fn identifier(&self) -> XKeyIdentifier
Returns the HASH160 of the chaincode
pub fn fingerprint(&self) -> Fingerprint
pub fn fingerprint(&self) -> Fingerprint
Returns the first four bytes of the identifier
