)

Functions

func GetRandomBytes

func GetRandomBytes(len int) ([]byte, error)

GetRandomBytes returns len random looking bytes

func GetRandomNonce

func GetRandomNonce() ([]byte, error)

GetRandomNonce returns a random byte array of length NonceSize

Types

type IdentitySerializer

type IdentitySerializer interface {
	// Serialize converts an identity to bytes
	Serialize() ([]byte, error)
}

IdentitySerializer serializes identities

type LocalSigner

type LocalSigner interface {
	SignatureHeaderMaker
	Signer
}

LocalSigner is a temporary stub interface which will be implemented by the local MSP

type SignatureHeaderCreator

type SignatureHeaderCreator struct {
	SignerSupport
}

SignatureHeaderCreator creates signature headers

type SignatureHeaderMaker

type SignatureHeaderMaker interface {
	// NewSignatureHeader creates a SignatureHeader with the correct signing identity and a valid nonce
	NewSignatureHeader() (*cb.SignatureHeader, error)
}

SignatureHeaderMaker creates a new SignatureHeader

type Signer

type Signer interface {
	// Sign a message and return the signature over the digest, or error on failure
	Sign(message []byte) ([]byte, error)
}

Signer signs messages

type SignerSupport

type SignerSupport interface {
	Signer
	IdentitySerializer
}

SignerSupport implements the needed support for LocalSigner
