Functions

func GenerateKey

func GenerateKey(rand io.Reader) (publicKey PublicKey, privateKey PrivateKey, err error)

GenerateKey generates a public/private key pair using entropy from rand. If rand is nil, crypto/rand.Reader will be used.

func Sign

func Sign(privateKey PrivateKey, message []byte) []byte

Sign is used to signature the transaction.

func Verify

func Verify(publicKey PublicKey, message, sig []byte) bool

Verify is used to confirm whether the signature is right.

Types

type PrivateKey

type PrivateKey ed25519.PrivateKey

PrivateKey is a byte array, []byte.

func (PrivateKey) Public

func (priv PrivateKey) Public() PublicKey

Public returns the public key fo the private key.

type PublicKey

type PublicKey ed25519.PublicKey

PublicKey is a byte array, []byte.
