Constants

const (
	// AddressLength is the expected length of the address
	AddressLength = 20
)

Lengths of hashes and addresses in bytes.

Functions

func FromECDSAPub

func FromECDSAPub(pub *ecdsa.PublicKey) []byte

func Keccak256

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

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

func S256

func S256() elliptic.Curve

S256 returns an instance of the secp256k1 curve.

Types

type Address

type Address [AddressLength]byte

Address represents the 20 byte address of an Ethereum account.

func BytesToAddress

func BytesToAddress(b []byte) Address

BytesToAddress returns Address with value b. If b is larger than len(h), b will be cropped from the left.

func PubkeyToAddress

func PubkeyToAddress(p ecdsa.PublicKey) Address

func (Address) Bytes

func (a Address) Bytes() []byte

Bytes gets the string representation of the underlying address.

func (Address) Hex

func (a Address) Hex() string

Hex returns an EIP55-compliant hex string representation of the address.

func (*Address) SetBytes

func (a *Address) SetBytes(b []byte)

SetBytes sets the address to the value of b. If b is larger than len(a) it will panic.

func (Address) String

func (a Address) String() string

String implements fmt.Stringer.
