Variables

var DefaultDerivationPath = DerivationPath{0x80000000 + 44, 0x80000000 + 60, 0x80000000 + 0, 0, 0}

DefaultDerivationPath is the default derivation path for Ethereum addresses

var S256 = btcec.S256()

S256 is the secp256k1 elliptic curve

Functions

func DecodeSignature

func DecodeSignature(sig []byte, chainID uint64) (R, S, V []byte)

It takes a signature and a chainID and returns the R, S, and V values of the signature.

Args:

sig ([]byte): the signature
chainID (uint64): The chain ID of the network you're signing for.

func Ecrecover

func Ecrecover(hash, signature []byte) (web3.Address, error)

func EcrecoverMsg

func EcrecoverMsg(msg, signature []byte) (web3.Address, error)

func EncodeSignature

func EncodeSignature(R, S []byte, V byte) ([]byte, error)

It encodes the signature of a transaction.

Args:

R ([]byte): The X coordinate of a point R on the curve
S ([]byte): the signature
V (byte): The recovery ID.

func Keccake256

func Keccake256(buf []byte) []byte

func ParsePrivateKey
