Functions

func CreateAddress

func CreateAddress(b common.Address, nonce uint64) common.Address

CreateAddress creates an ethereum address given the bytes and the nonce

func CreateAddress2

func CreateAddress2(b common.Address, salt [32]byte, inithash []byte) common.Address

CreateAddress2 creates an ethereum address given the address bytes, initial contract code hash and a salt.

func HashData

func HashData(kh KeccakState, data []byte) (h common.Hash)

HashData hashes the provided data using the KeccakState and returns a 32 byte hash

func Keccak256

func Keccak256(data ...[]byte) []byte

Keccak256 calculates and returns the Keccak256 hash of the input data.

func Keccak256Hash

func Keccak256Hash(data ...[]byte) (h common.Hash)

Keccak256Hash calculates and returns the Keccak256 hash of the input data, converting it to an internal Hash data structure.

func Keccak512

func Keccak512(data ...[]byte) []byte

Keccak512 calculates and returns the Keccak512 hash of the input data.

Types

type KeccakState

type KeccakState interface {
	hash.Hash
	Read([]byte) (int, error)
}

KeccakState wraps sha3.state. In addition to the usual hash methods, it also supports Read to get a variable amount of data from the hash state. Read is faster than Sum because it doesn't copy the internal state, but also modifies the internal state.

func NewKeccakState

func NewKeccakState() KeccakState

NewKeccakState creates a new KeccakState
