	tokenString string,
	holderPublicKey ed25519.PublicKey,
	expectedAudience string,
	expectedNonce string,
) (*VPClaims, error)

VerifyPresentation verifies a PASETO VP token and returns the claims

type VerifiablePresentation

type VerifiablePresentation struct {
	Context              []string `json:"@context"`
	Type                 []string `json:"type"`
