Struct miden_core::crypto::dsa::rpo_falcon512::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.

For Falcon-512, the first byte of the expanded public key is always equal to log2(512) i.e., 9.

Implementations

impl PublicKey

pub fn new(pk: [u8; 897]) -> Result<PublicKey, FalconError>

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

Errors

Returns an error if the decoding of the public key fails.

pub fn verify(&self, message: [BaseElement; 4], 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<(), Error>

Formats the value using the given formatter.

impl From<PublicKey> for [BaseElement; 4]

fn from(key: PublicKey) -> [BaseElement; 4]

Converts to this type from the input type.

impl PartialEq for PublicKey

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