A signature signer.

Associated Types

type Algorithm: SignatureAlgorithm

The algorithm of this signer.

type SecretKey: Clone

The secret key used by this signer.

type PublicKey: Copy

The public key used by this signer.

type Signature: Signature

The signature type produced by this signer.

Required methods

fn new() -> Self

Creates a new signer.

fn sign_populated(
    &self,
    hashed: [u8; 32],
    secret_key: &Self::SecretKey
) -> Self::Signature

Signs a 256 bit hashed data with the secret key.

fn to_public_key(&self, secret_key: &Self::SecretKey) -> Self::PublicKey

Converts a secret key to its public counterpart.

fn serialize_public_key(&self, public_key: &Self::PublicKey) -> [u8; 64]

Serializes a public key. Excluding the leading 0x04.

Provided methods

fn sign(
    &self,
    hasher: impl FlowHasher,
    secret_key: &Self::SecretKey
) -> Self::Signature

Creates a signature by consuming a populated hasher and a secret key.
