Struct schnorr::keys::PublicKey

pub struct PublicKey(_);

An Schnorr public key.

Methods

impl PublicKey

pub fn as_compressed(&self) -> &CompressedRistretto

Access the compressed Ristretto form

pub fn into_compressed(self) -> CompressedRistretto

Extract the compressed Ristretto form

pub fn as_point(&self) -> &RistrettoPoint

Access the point form

pub fn into_point(self) -> RistrettoPoint

Extract the point form

pub fn from_compressed(
    compressed: CompressedRistretto
) -> Result<PublicKey, SchnorrError>

Decompress into the PublicKey format that also retains the compressed form.

pub fn from_point(point: RistrettoPoint) -> PublicKey

Compress into the PublicKey format that also retains the uncompressed form.

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

Convert this public key to a byte array.

pub fn as_bytes<'a>(&'a self) -> &'a [u8; 32]

View this public key as a byte array.

pub fn from_bytes(bytes: &[u8]) -> Result<PublicKey, SchnorrError>

Construct a PublicKey from a slice of bytes.

Warning

The caller is responsible for ensuring that the bytes passed into this method actually represent a curve25519_dalek::curve::CompressedRistretto and that said compressed point is actually a point on the curve.

Example

use schnorr::*;

let public_key_bytes: [u8; PUBLIC_KEY_LENGTH] = [
   215,  90, 152,   1, 130, 177,  10, 183, 213,  75, 254, 211, 201, 100,   7,  58,
    14, 225, 114, 243, 218, 166,  35,  37, 175,   2,  26, 104, 247,   7,   81, 26];

let public_key = PublicKey::from_bytes(&public_key_bytes)?;

Returns

A Result whose okay value is an Schnorr PublicKey or whose error value is an SchnorrError describing the error that occurred.

pub fn from_secret(secret_key: &SecretKey) -> PublicKey

Derive this public key from its corresponding SecretKey.

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 Copy for PublicKey

impl Debug for PublicKey

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

Formats the value using the given formatter.

impl Default for PublicKey

fn default() -> PublicKey

Returns the "default value" for a type.

impl<'d> Deserialize<'d> for PublicKey

fn deserialize<D>(deserializer: D) -> Result<Self, D::Error> where
    D: Deserializer<'d>, 

Deserialize this value from the given Serde deserializer.

impl Eq for PublicKey

impl From<SecretKey> for PublicKey

fn from(source: SecretKey) -> PublicKey

Performs the conversion.

impl Ord for PublicKey

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

This method returns an [Ordering] between self and other.

#[must_use]fn max(self, other: Self) -> Self

Compares and returns the maximum of two values.

#[must_use]fn min(self, other: Self) -> Self

Compares and returns the minimum of two values.

#[must_use]fn clamp(self, min: Self, max: Self) -> Self

🔬 This is a nightly-only experimental API. (clamp)

Restrict a value to a certain interval.

impl PartialEq<PublicKey> for PublicKey

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

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

#[must_use]fn ne(&self, other: &Rhs) -> bool

This method tests for !=.

impl PartialOrd<PublicKey> for PublicKey

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

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

#[must_use]fn lt(&self, other: &Rhs) -> bool

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

#[must_use]fn le(&self, other: &Rhs) -> bool

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

#[must_use]fn gt(&self, other: &Rhs) -> bool

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

#[must_use]fn ge(&self, other: &Rhs) -> bool

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

impl Readable for PublicKey

fn read(reader: &mut dyn Reader) -> Result<PublicKey, Error>

Reads the data necessary to this Readable from the provided reader

impl Serialize for PublicKey

fn serialize<S>(&self, serializer: S) -> Result<S::Ok, S::Error> where
    S: Serializer, 

Serialize this value into the given Serde serializer.

impl Writeable for PublicKey

fn write<W: Writer>(&self, writer: &mut W) -> Result<(), Error>

Write the data held by this Writeable to the provided writer

impl Zeroize for PublicKey

fn zeroize(&mut self)

Zero out this object from memory using Rust intrinsics which ensure the zeroization operation is not "optimized away" by the compiler.
