Struct miden_crypto::dsa::rpo_falcon512::KeyPair

pub struct KeyPair { /* private fields */ }

A key pair (public and secret keys) for signing messages.

The secret key is a byte array of length [PK_LEN]. The public key is a byte array of length [SK_LEN].

Implementations

impl KeyPair

pub fn new() -> Result<Self, FalconError>

Generates a (public_key, secret_key) key pair from OS-provided randomness.

Errors

Returns an error if key generation fails.

pub fn from_seed(seed: &[u8; 40]) -> Result<Self, FalconError>

Generates a (public_key, secret_key) key pair from the provided seed.

Errors

Returns an error if key generation fails.

pub fn public_key(&self) -> PublicKey

Returns the public key corresponding to this key pair.

pub fn expanded_public_key(&self) -> [u8; 897]

Returns the expanded public key corresponding to this key pair.

pub fn sign(&self, message: Word) -> Result<Signature, FalconError>

Signs a message with a secret key and a seed.

Errors

Returns an error of signature generation fails.

Trait Implementations

impl Clone for KeyPair

fn clone(&self) -> KeyPair

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for KeyPair

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

Formats the value using the given formatter.

impl Deserializable for KeyPair

fn read_from<R: ByteReader>( source: &mut R ) -> Result<Self, DeserializationError>

Reads a sequence of bytes from the provided source, attempts to deserialize these bytes into Self, and returns the result.

fn read_from_bytes(bytes: &[u8]) -> Result<Self, DeserializationError>

Attempts to deserialize the provided bytes into Self and returns the result.

fn read_batch_from<R>( source: &mut R, num_elements: usize ) -> Result<Vec<Self>, DeserializationError>where R: ByteReader,

Reads a sequence of bytes from the provided source, attempts to deserialize these bytes into a vector with the specified number of Self elements, and returns the result.

impl PartialEq for KeyPair

fn eq(&self, other: &KeyPair) -> 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 Serializable for KeyPair

fn write_into<W: ByteWriter>(&self, target: &mut W)

Serializes self into bytes and writes these bytes into the target.

fn to_bytes(&self) -> Vec<u8>

Serializes self into a vector of bytes.

fn write_batch_into<W>(source: &[Self], target: &mut W)where W: ByteWriter,

Serializes all elements of the source and writes these bytes into the target.

fn get_size_hint(&self) -> usize

Returns an estimate of how many bytes are needed to represent self.
