Functions ¶

func GenerateKeyPair ¶

func GenerateKeyPair() ([]byte, []byte)

func GeneratePubKey ¶

func GeneratePubKey(seckey []byte) ([]byte, error)

func RecoverPubkey ¶

func RecoverPubkey(msg []byte, sig []byte) ([]byte, error)

RecoverPubkey returns the the public key of the signer. msg must be the 32-byte hash of the message to be signed. sig must be a 65-byte compact ECDSA signature containing the recovery id as the last element.

func Sign ¶

func Sign(msg []byte, seckey []byte) ([]byte, error)
