Types

type Signature

type Signature interface {
	Code() uint64
	Size() uint64
	Bytes() []byte
	// Raw signature (without signature algorithm info).
	Raw() []byte
}

func Decode

func Decode(b []byte) Signature

func NewNonStandard

func NewNonStandard(name string, raw []byte) Signature

func NewSignature

func NewSignature(code uint64, raw []byte) Signature

type SignatureView

type SignatureView interface {
	Signature
	// Verify that the signature was produced by the given message.
	Verify(msg []byte, signer Verifier) bool
}

func NewSignatureView

func NewSignatureView(s Signature) SignatureView

type Verifier

type Verifier interface {
	// Verify takes a byte encoded message and verifies that it is signed by
	// corresponding signer.
	Verify(msg []byte, sig Signature) bool
}

Verifier represents an entity that can verify signatures.
