Functions

func NewG2PublicKeyVerifier

func NewG2PublicKeyVerifier(nonce []byte) *verifier.PublicKeyVerifier

NewG2PublicKeyVerifier creates a signature verifier that verifies a BbsBlsSignatureProof2020 signature taking Bls12381G2Key2020 public key bytes as input.

Types

type Suite

type Suite struct {
	suite.SignatureSuite
	// contains filtered or unexported fields
}

Suite implements EcdsaSecp256k1Signature2019 signature suite.

func New

func New(opts ...suite.Opt) *Suite

New an instance of Linked Data Signatures for the suite.

func (*Suite) Accept

func (s *Suite) Accept(t string) bool

Accept will accept only EcdsaSecp256k1Signature2019 signature type.

func (*Suite) GetCanonicalDocument

func (s *Suite) GetCanonicalDocument(doc map[string]interface{}, opts ...jsonld.ProcessorOpts) ([]byte, error)

GetCanonicalDocument will return normalized/canonical version of the document. EcdsaSecp256k1Signature2019 signature suite uses RDF Dataset Normalization as canonicalization algorithm.

func (*Suite) GetDigest

func (s *Suite) GetDigest(doc []byte) []byte

GetDigest returns the doc itself as we would process N-Quads statements as messages to be signed/verified.

func (*Suite) SelectiveDisclosure

func (s *Suite) SelectiveDisclosure(doc map[string]interface{}, revealDoc map[string]interface{},
	pubKeyBytes, nonce []byte, opts ...jsonld.ProcessorOpts) (map[string]interface{}, error)

SelectiveDisclosure creates selective disclosure from the input doc which must have a BBS+ proof (with BbsBlsSignature2020 type).
