Implementations§

§

impl CompressedPublicKey

pub fn pubkey_hash(&self) -> PubkeyHash

Returns bitcoin 160-bit hash of the public key

pub fn wpubkey_hash(&self) -> WPubkeyHash

Returns bitcoin 160-bit hash of the public key for witness program

pub fn p2wpkh_script_code(&self) -> ScriptBuf

Returns the script code used to spend a P2WPKH input.

pub fn write_into<W>(&self, writer: &mut W) -> Result<(), Error>
where W: Write + ?Sized,

Write the public key into a writer

pub fn read_from<R>(reader: &mut R) -> Result<CompressedPublicKey, Error>
where R: Read + ?Sized,

Read the public key from a reader

This internally reads the first byte before reading the rest, so use of a BufReader is recommended.

pub fn to_bytes(&self) -> [u8; 33]

Serializes the public key.

As the type name suggests, the key is serialzied in compressed format.

Note that this can be used as a sort key to get BIP67-compliant sorting. That’s why this type doesn’t have the to_sort_key method - it would duplicate this one.

pub fn from_slice(data: &[u8]) -> Result<CompressedPublicKey, Error>

Deserialize a public key from a slice

pub fn from_private_key<C>( secp: &Secp256k1<C>, sk: &PrivateKey ) -> Result<CompressedPublicKey, UncompressedPublicKeyError>
where C: Signing,

Computes the public key as supposed to be used with this secret

pub fn verify<C>( &self, secp: &Secp256k1<C>, msg: &Message, sig: &Signature ) -> Result<(), Error>
where C: Verification,

Checks that sig is a valid ECDSA signature for msg using this public key.
