Struct PublicKey

pub struct PublicKey(/* private fields */);

A public key for verifying signatures.

The public key is a Word (i.e., 4 field elements) that is the hash of the coefficients of the polynomial representing the raw bytes of the expanded public key. The hash is computed using Rpo256.

Implementations

impl PublicKey

pub fn new(pub_key: Word) -> Self

Returns a new PublicKey which is a commitment to the provided expanded public key.

pub fn verify(&self, message: Word, signature: &Signature) -> bool

Verifies the provided signature against provided message and this public key.

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 From<PubKeyPoly> for PublicKey

fn from(pk_poly: PubKeyPoly) -> Self

Converts to this type from the input type.

impl From<PublicKey> for Word

fn from(key: PublicKey) -> Self

Converts to this type from the input type.

impl PartialEq for PublicKey

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

Tests for self and other values to be equal, and is used by ==.

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

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