Struct ckb_crypto::secp::Pubkey

pub struct Pubkey { /* private fields */ }

A Secp256k1 512-bit public key, used for verification of signatures

Implementations

impl Pubkey

pub fn verify(
    &self,
    message: &Message,
    signature: &Signature
) -> Result<(), Error>

Checks that signature is a valid ECDSA signature for message using the public key pubkey

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

Serialize 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 from_slice(data: &[u8]) -> Result<Self, Error>

Creates a new Pubkey from a slice

Methods from Deref<Target = H512>

pub fn as_bytes(&self) -> &[u8]

Converts Self to a byte slice.

Trait Implementations

impl Clone for Pubkey

fn clone(&self) -> Pubkey

Returns a copy of the value.

const fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Pubkey

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Deref for Pubkey

type Target = H512

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.

impl Display for Pubkey

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl From<[u8; 64]> for Pubkey

fn from(key: [u8; 64]) -> Self

Converts to this type from the input type.

impl From<H512> for Pubkey

fn from(key: H512) -> Self

Converts to this type from the input type.

impl From<PublicKey> for Pubkey

fn from(key: PublicKey) -> Self

Converts to this type from the input type.

impl Hash for Pubkey

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)where
    H: Hasher,
    Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq<Pubkey> for Pubkey

fn eq(&self, other: &Pubkey) -> bool

This method tests for self and other values to be equal, and is used by ==.

const fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
