Types

type Keypair

type Keypair struct {
	// contains filtered or unexported fields
}

func GenerateKeypair

func GenerateKeypair() (*Keypair, error)

func NewKeypair

func NewKeypair(pk ecdsa.PrivateKey) *Keypair

func NewKeypairFromPrivateKey

func NewKeypairFromPrivateKey(priv []byte) (*Keypair, error)

func NewKeypairFromString

func NewKeypairFromString(priv string) (*Keypair, error)

NewKeypairFromPrivateKey parses a string for a hex private key. Must be at least PrivateKeyLength long.

func (*Keypair) Address

func (kp *Keypair) Address() string

Address returns the Ethereum address format

func (*Keypair) CommonAddress

func (kp *Keypair) CommonAddress() common.Address

CommonAddress returns the Ethereum address in the common.Address Format

func (*Keypair) Decode

func (kp *Keypair) Decode(in []byte) error

Decode initializes the keypair using the input

func (*Keypair) Encode

func (kp *Keypair) Encode() []byte

Encode dumps the private key as bytes

func (*Keypair) PublicKey

func (kp *Keypair) PublicKey() string

PublicKey returns the public key hex encoded

func (*Keypair) Sign

func (kp *Keypair) Sign(digestHash []byte) ([]byte, error)

Sign calculates an ECDSA signature. The produced signature is in the [R || S || V] format where V is 0 or 1.
