Struct bitcoin::util::key::PublicKey

pub struct PublicKey {
    pub compressed: bool,
    pub inner: PublicKey,
}

A Bitcoin ECDSA public key

Fields

compressed: bool

Whether this public key should be serialized as compressed

inner: PublicKey

The actual ECDSA key

Implementations

impl PublicKey

pub fn new(key: PublicKey) -> PublicKey

Constructs compressed ECDSA public key from the provided generic Secp256k1 public key

pub fn new_uncompressed(key: PublicKey) -> PublicKey

Constructs uncompressed (legacy) ECDSA public key from the provided generic Secp256k1 public key

pub fn pubkey_hash(&self) -> PubkeyHash

Returns bitcoin 160-bit hash of the public key

pub fn wpubkey_hash(&self) -> Option<WPubkeyHash>

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

pub fn write_into<W: Write>(&self, writer: W) -> Result<(), Error>

Write the public key into a writer

pub fn read_from<R: Read>(reader: R) -> Result<Self, Error>

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) -> Vec<u8>

Serialize the public key to bytes

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

Deserialize a public key from a slice

pub fn from_private_key<C: Signing>(
    secp: &Secp256k1<C>,
    sk: &PrivateKey
) -> PublicKey

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