Types

type SignableData

type SignableData interface {
	GetProgramHashes() ([]common.Uint160, error)
	SetPrograms([]*pb.Program)
	GetPrograms() []*pb.Program
	SerializeUnsigned(io.Writer) error
}

SignableData describe the data need be signed.

type Signer

type Signer interface {

	//get signer's private key
	PrivKey() []byte

	//get signer's public key
	PubKey() *crypto.PubKey
}

Signer is the abstract interface of user's information(Keys) for signing data.
