Functions

func CreateHolderBinding

func CreateHolderBinding(info *BindingInfo) (string, error)

CreateHolderBinding will create holder binding from binding info.

func CreatePresentation

func CreatePresentation(combinedFormatForIssuance string, claimsToDisclose []string, opts ...Option) (string, error)

CreatePresentation is a convenience method to assemble combined format for presentation using selected disclosures (claimsToDisclose) and optional holder binding. This call assumes that combinedFormatForIssuance has already been parsed and verified using Parse() function.

Types

type BindingInfo

type BindingInfo struct {
	Payload BindingPayload
	Signer  jose.Signer
}

BindingInfo defines holder binding payload and signer.

type BindingPayload

type BindingPayload struct {
	Nonce    string           `json:"nonce,omitempty"`
	Audience string           `json:"aud,omitempty"`
	IssuedAt *jwt.NumericDate `json:"iat,omitempty"`
}

BindingPayload represents holder binding payload.

type Claim

type Claim struct {
	Disclosure string
	Name       string
	Value      interface{}
}

Claim defines claim.

func Parse

func Parse(combinedFormatForIssuance string, opts ...ParseOpt) ([]*Claim, error)

Parse parses issuer SD-JWT and returns claims that can be selected.

type NoopSignatureVerifier

type NoopSignatureVerifier struct {
}

NoopSignatureVerifier is no-op signature verifier (signature will not get checked).

func (*NoopSignatureVerifier) Verify

func (sv *NoopSignatureVerifier) Verify(joseHeaders jose.Headers, payload, signingInput, signature []byte) error

Verify implements signature verification.

type Option

type Option func(opts *options)

Option is a holder option.

func WithHolderBinding

func WithHolderBinding(info *BindingInfo) Option

WithHolderBinding option to set optional holder binding.

type ParseOpt

type ParseOpt func(opts *parseOpts)

ParseOpt is the SD-JWT Parser option.

func WithJWTDetachedPayload

func WithJWTDetachedPayload(payload []byte) ParseOpt

WithJWTDetachedPayload option is for definition of JWT detached payload.

func WithSignatureVerifier

func WithSignatureVerifier(signatureVerifier jose.SignatureVerifier) ParseOpt

WithSignatureVerifier option is for definition of JWT detached payload.
