Struct SigningKey 

pub struct SigningKey { /* private fields */ }

Ed25519 signing key which can be used to produce signatures.

Invariant: verifying_key is always the public key of secret_key. This prevents the signing function oracle attack.

Implementations

impl SigningKey

pub fn verifying_key(&self) -> VerifyingKey

Get the VerifyingKey for this SigningKey.

pub fn from_bytes(secret_key: &SecretKey) -> Self

Construct a SigningKey from a SecretKey.

pub fn is_valid_signature(&self, message: &[u8], signature: &Signature) -> bool

Verify a signature on a message with this signing key’s public key.

pub fn sign(&self, message: &[u8]) -> Signature

Sign a message with this signing key’s secret key.

 use openzeppelin_crypto::eddsa::{SecretKey, SigningKey, SECRET_KEY_LENGTH};

 let secret_key: SecretKey = [1u8; SECRET_KEY_LENGTH];
 let signing_key = SigningKey::from_bytes(&secret_key);
 let message = b"Sign me!";

 let signature = signing_key.sign(message);
 assert!(signing_key.is_valid_signature(message, &signature));

Trait Implementations

impl Clone for SigningKey

fn clone(&self) -> SigningKey

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl PartialEq for SigningKey

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