Struct libp2p_core::identity::secp256k1::PublicKey

pub struct PublicKey(_);

Available on crate feature secp256k1 only.

A Secp256k1 public key.

Implementations

impl PublicKey

pub fn verify(&self, msg: &[u8], sig: &[u8]) -> bool

Verify the Secp256k1 signature on a message using the public key.

pub fn verify_hash(&self, msg: &[u8], sig: &[u8]) -> bool

Verify the Secp256k1 DER-encoded signature on a raw 256-bit message using the public key.

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

Encode the public key in compressed form, i.e. with one coordinate represented by a single bit.

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

Encode the public key in uncompressed form.

pub fn decode(k: &[u8]) -> Result<PublicKey, DecodingError>

Decode a public key from a byte slice in the the format produced by encode.

Trait Implementations

impl Clone for PublicKey

fn clone(&self) -> PublicKey

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for PublicKey

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

Formats the value using the given formatter.

impl Hash for PublicKey

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 Ord for PublicKey

fn cmp(&self, other: &Self) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Selfwhere
    Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Selfwhere
    Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Selfwhere
    Self: Sized + PartialOrd<Self>,

Restrict a value to a certain interval.

impl PartialEq<PublicKey> for PublicKey

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

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

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.

impl PartialOrd<PublicKey> for PublicKey

fn partial_cmp(&self, other: &Self) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

This method tests less than (for self and other) and is used by the < operator.

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

This method tests less than or equal to (for self and other) and is used by the <= operator.

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

This method tests greater than (for self and other) and is used by the > operator.

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

This method tests greater than or equal to (for self and other) and is used by the >= operator.
