Types

type MetaData

type MetaData struct {
	keys.PublicKeyID
	//ValidSince defines the time from which on this signature is valid. ValidSince is represented as seconds since the UNIX epoch UTC.
	ValidSince int64
	//ValidUntil defines the time after which this signature is not valid anymore. ValidUntil is represented as seconds since the UNIX epoch UTC.
	ValidUntil int64
}

MetaData contains meta data of the signature

type Sig

type Sig struct {
	keys.PublicKeyID
	//ValidSince defines the time from which on this signature is valid. ValidSince is represented as seconds since the UNIX epoch UTC.
	ValidSince int64
	//ValidUntil defines the time after which this signature is not valid anymore. ValidUntil is represented as seconds since the UNIX epoch UTC.
	ValidUntil int64
	//Data holds the signature data
	Data interface{}
	// contains filtered or unexported fields
}

Sig contains meta data of the signature and the signature data itself.

func (Sig) CompareTo

func (sig Sig) CompareTo(s Sig) int

CompareTo compares two signature objects and returns 0 if they are equal, 1 if sig is greater than s and -1 if sig is smaller than s

func (Sig) MarshalCBOR

func (sig Sig) MarshalCBOR(w *cbor.CBORWriter) error

MarshalCBOR implements a CBORMarshaler.

func (Sig) MetaData

func (sig Sig) MetaData() MetaData

MetaData returns the signatures metaData

func (*Sig) SignData

func (sig *Sig) SignData(privateKey interface{}, encoding []byte) error

SignData adds signature meta data to encoding. It then signs the encoding with privateKey and updates sig.Data field with the generated signature In case of an error an error is returned indicating the cause, otherwise nil is returned

func (Sig) String

func (sig Sig) String() string

String implements Stringer interface

func (*Sig) UnmarshalArray

func (sig *Sig) UnmarshalArray(in []interface{}) error

UnmarshalArray takes in a CBOR decoded array and populates Sig.

func (*Sig) VerifySignature

func (sig *Sig) VerifySignature(publicKey interface{}, encoding []byte) bool

VerifySignature adds signature meta data to the encoding. It then signs the encoding with privateKey and compares the resulting signature with the sig.Data. Returns true if there exist signatures and they are identical
