Required Associated Types

type BigUint: BigUintApi + 'static

Numeric type used in some of the Arwen hooks.

Required Methods

fn sha256(&self, data: &[u8]) -> H256

fn keccak256(&self, data: &[u8]) -> H256

fn verify_bls(&self, key: &[u8], message: &[u8], signature: &[u8]) -> bool

fn verify_ed25519(&self, key: &[u8], message: &[u8], signature: &[u8]) -> bool

fn verify_secp256k1(&self, key: &[u8], message: &[u8], signature: &[u8]) -> bool

Note: the signature is minimum 2 bytes in length, the second byte encodes the length of the remaining signature bytes.
