Implementations

impl KeyPair

pub fn generate() -> Self

Generate a new random keypair.

pub fn from_bytes(secret_bytes: &[u8; 32]) -> Self

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

Get the secret key bytes.

pub fn public_key(&self) -> PublicKey

Get the public key.

pub fn sign(&self, message: &[u8]) -> [u8; 64]

Sign a message and return the signature bytes.
