Functions

func DecodeSecp256k1PrivateKey

func DecodeSecp256k1PrivateKey(data []byte) (*ecdsa.PrivateKey, error)

DecodeSecp256k1PrivateKey decodes raw ECDSA private key.

func EncodeSecp256k1PrivateKey

func EncodeSecp256k1PrivateKey(k *ecdsa.PrivateKey) []byte

EncodeSecp256k1PrivateKey encodes raw ECDSA private key.

func GenerateSecp256k1Key

func GenerateSecp256k1Key() (*ecdsa.PrivateKey, error)

GenerateSecp256k1Key generates an ECDSA private key using secp256k1 elliptic curve.

func LegacyKeccak256

func LegacyKeccak256(data []byte) ([]byte, error)

func NewEthereumAddress

func NewEthereumAddress(p ecdsa.PublicKey) ([]byte, error)

NewEthereumAddress returns a binary representation of ethereum blockchain address. This function is based on github.com/ethereum/go-ethereum/crypto.PubkeyToAddress.

func NewOverlayAddress

func NewOverlayAddress(p ecdsa.PublicKey, networkID uint64) (swarm.Address, error)

NewOverlayAddress constructs a Swarm Address from ECDSA private key.

func Recover

func Recover(signature, data []byte) (*ecdsa.PublicKey, error)

Recover verifies signature with the data base provided. It is using `btcec.RecoverCompact` function
