Struct PublicKey 

pub struct PublicKey { /* private fields */ }

Ed25519 public key for signature verification (RFC 8032).

Verifying a signature

use crypto::curve25519::ed25519::{PublicKey, SecretKey};

let priv_key = SecretKey::generate();
let pub_key = priv_key.public_key();
let sig = priv_key.sign(b"message");
assert!(pub_key.verify(b"message", &sig).is_ok());

Deserializing from bytes

use crypto::curve25519::ed25519::PublicKey;

let bytes = [0u8; 32]; // replace with a real public key
let pub_key = PublicKey::from_bytes(&bytes);

Implementations

impl PublicKey

pub fn from_bytes(key: &[u8; 32]) -> Result<PublicKey, EllipticCurveError>

pub fn verify( &self, message: &[u8], signature: &[u8; 64], ) -> Result<(), EllipticCurveError>

pub fn to_bytes(&self) -> [u8; 32]

pub fn to_montgomery_u(&self) -> Option<FieldElement>

Trait Implementations

impl Clone for PublicKey

fn clone(&self) -> PublicKey

Returns a duplicate 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 Eq for PublicKey

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.

impl StructuralPartialEq for PublicKey

impl TryFrom<&PublicKey> for PublicKey

type Error = EllipticCurveError

fn try_from(ed25519_public_key: &PublicKey) -> Result<Self, Self::Error>

Performs the conversion.

impl TryFrom<&[u8]> for PublicKey

type Error = EllipticCurveError

The type returned in the event of a conversion error.

fn try_from(bytes: &[u8]) -> Result<Self, Self::Error>

Performs the conversion.
