func Ecrecover

func Ecrecover(hash, sig []byte) ([]byte, error)

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 Keccak256

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

func Keccak256Hash

func Sha256

func Sha256(data []byte) []byte

func Sha3

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

Deprecated: For backward compatibility as other packages depend on these

func Sha3Hash

func Sha3Hash(data ...[]byte) common.Hash

func SigToPub

func SigToPub(hash, sig []byte) (*ecdsa.PublicKey, error)

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

func ValidateSignatureValues

func ValidateSignatureValues(v byte, r, s *big.Int, homestead bool) bool

func WriteECDSAKey

func WriteECDSAKey(to io.Writer, key *ecdsa.PrivateKey) (int, error)

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