Types

type SignableData

type SignableData interface {
	interfaces.CodeContainer

	////Get the the SignableData's program hashes
	GetProgramHashes() ([]common.Address, error)

	SetPrograms([]*program.Program)

	GetPrograms() []*program.Program

	//TODO: add SerializeUnsigned
	SerializeUnsigned(io.Writer) error
}

SignableData describe the data need be signed.

type Signer

type Signer interface {
	//get signer's private key
	PrivKey() keypair.PrivateKey

	//get signer's public key
	PubKey() keypair.PublicKey
}

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