Implementations

impl LegacyPk

pub const fn compressed(pubkey: PublicKey) -> LegacyPk

pub const fn uncompressed(pubkey: PublicKey) -> LegacyPk

pub fn from_bytes( bytes: impl AsRef<[u8]>, ) -> Result<LegacyPk, InvalidPubkey<65>>

pub fn to_vec(&self) -> Vec<u8>

Methods from Deref<Target = PublicKey>

pub fn cmp_fast_unstable(&self, other: &PublicKey) -> Ordering

Like cmp::Cmp but faster and with no guarantees across library versions.

The Cmp implementation for FFI types is stable but slow because it first serializes self and other before comparing them. This function provides a faster comparison if you know that your types come from the same library version.

pub fn eq_fast_unstable(&self, other: &PublicKey) -> bool

Like cmp::Eq but faster and with no guarantees across library versions.

The Eq implementation for FFI types is stable but slow because it first serializes self and other before comparing them. This function provides a faster equality check if you know that your types come from the same library version.

pub fn as_ptr(&self) -> *const PublicKey

👎Deprecated since 0.25.0: Use Self::as_c_ptr if you need to access the FFI layer

Obtains a raw const pointer suitable for use with FFI functions.

pub fn as_mut_ptr(&mut self) -> *mut PublicKey

👎Deprecated since 0.25.0: Use Self::as_mut_c_ptr if you need to access the FFI layer

Obtains a raw mutable pointer suitable for use with FFI functions.

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

Serializes the key as a byte-encoded pair of values. In compressed form the y-coordinate is represented by only a single bit, as x determines it up to one bit.

pub fn serialize_uncompressed(&self) -> [u8; 65]

Serializes the key as a byte-encoded pair of values, in uncompressed form.

pub fn combine(&self, other: &PublicKey) -> Result<PublicKey, Error>

Adds a second key to this one, returning the sum.

Errors

If the result would be the point at infinity, i.e. adding this point to its own negation.

Examples

use secp256k1::{rand, Secp256k1};

let secp = Secp256k1::new();
let mut rng = rand::thread_rng();
let (_, pk1) = secp.generate_keypair(&mut rng);
let (_, pk2) = secp.generate_keypair(&mut rng);
let sum = pk1.combine(&pk2).expect("It's improbable to fail for 2 random public keys");

pub fn x_only_public_key(&self) -> (XOnlyPublicKey, Parity)

Returns the XOnlyPublicKey (and it’s Parity) for this PublicKey.

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.
