func Encrypt

func Encrypt(pub *ecdsa.PublicKey, message []byte) ([]byte, error)

func FromECDSA

func FromECDSA(prv *ecdsa.PrivateKey) []byte

func FromECDSAPub

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

func GenerateKey

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

func HexToECDSA

func HexToECDSA(hexkey string) (*ecdsa.PrivateKey, error)

HexToECDSA parses a secp256k1 private key.

func IndexOf

func IndexOf(slice []string, value string) int64

func Keccak256

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

func Keccak256Hash

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

func LoadECDSA

func LoadECDSA(file string) (*ecdsa.PrivateKey, error)

LoadECDSA loads a secp256k1 private key from the given file. The key data is expected to be hex-encoded.

func SaveECDSA

func SaveECDSA(file string, key *ecdsa.PrivateKey) error

SaveECDSA saves a secp256k1 private key to the given file with restrictive permissions. The key data is saved hex-encoded.

func Sha256

func Sha256(data []byte) []byte

func Sha3

func Sha3(data ...[]byte) []byte

func Sign

func Sign(hash []byte, prv *ecdsa.PrivateKey) (sig []byte, err error)

func ToECDSA

func ToECDSA(prv []byte) *ecdsa.PrivateKey

New methods using proper ecdsa keys from the stdlib

func ToECDSAPub
