Struct SigningKey

pub struct SigningKey<D: Domain> { /* private fields */ }

A decaf377-rdsa signing key.

Implementations

impl<D: Domain> SigningKey<D>

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

Returns the byte encoding of the signing key.

This is the same as .into(), but does not require type inference.

impl SigningKey<SpendAuth>

pub fn randomize(&self, randomizer: &Fr) -> SigningKey<SpendAuth>

Randomize this public key with the given randomizer.

impl<D: Domain> SigningKey<D>

pub fn new<R: RngCore + CryptoRng>(rng: R) -> SigningKey<D>

Create a new signing key from the supplied rng.

pub fn new_from_field(sk: Fr) -> SigningKey<D>

Use the supplied field element as the signing key directly.

Warning

This function exists to allow custom key derivation; it’s the caller’s responsibility to ensure that the input was generated securely.

pub fn sign<R: RngCore + CryptoRng>(&self, rng: R, msg: &[u8]) -> Signature<D>

Create a signature for domain D on msg using this SigningKey.

pub fn sign_deterministic(&self, msg: &[u8]) -> Signature<D>

Create a signature for domain D on msg using this SigningKey.

Prefer sign, unless you know you need deterministic signatures.

Trait Implementations

impl<D: Clone + Domain> Clone for SigningKey<D>

fn clone(&self) -> SigningKey<D>

Returns a copy of the value.

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

Performs copy-assignment from source.
