Functions

func CheckProof

func CheckProof(
	message *cose.Sign1Message,
	proofChecker ProofChecker,
	expectedProofIssuer *string,
	msg []byte,
	signature []byte,
) error

CheckProof checks that jwt have correct signature.

func Parse

func Parse(cwtSerialized []byte) (*cose.Sign1Message, error)

Parse parses input CWT in serialized form into JSON Web Token.

func ParseAndCheckProof

func ParseAndCheckProof(
	cwtSerialized []byte,
	proofChecker ProofChecker,
	checkIssuer bool,
) (*cose.Sign1Message, []byte, error)

ParseAndCheckProof parses input JWT in serialized form into JSON Web Token and check signature proof. if checkIssuer set to true, will check if issuer set by "iss" own key set by "kid" header.

Types

type ProofChecker

type ProofChecker interface {
	CheckCWTProof(
		checkCWTRequest checker.CheckCWTProofRequest,
		expectedProofIssuer string,
		msg []byte,
		signature []byte,
	) error
}

ProofChecker used to check proof of jwt vc.

type ProofCreator

type ProofCreator interface {
	SignCWT(params SignParameters, cborData []byte) ([]byte, error)
}

ProofCreator defines signer interface which is used to sign VC JWT.

type SignParameters

type SignParameters struct {
	KeyID  string
	CWTAlg cose.Algorithm
}

SignParameters contains parameters of signing for cwt vc.

type Verifier

type Verifier struct {
	ProofChecker ProofChecker
	// contains filtered or unexported fields
}

Verifier verifies CWT proof.

func (*Verifier) Verify

func (v *Verifier) Verify(
	keyMaterial string,
	keyID string,
	algo cose.Algorithm,
	msg []byte,
	sign []byte,
) error

Verify verifies CWT proof.
