Types

type Verifier

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

Verifier is a client helper library for verifying request and responses.

func New

func New(vrf vrf.PublicKey,
	hasher hashers.MapHasher,
	mapPubKey crypto.PublicKey,
	logVerifier client.LogVerifier) *Verifier

New creates a new instance of the client verifier.

func (*Verifier) NewMutation

func (v *Verifier) NewMutation(
	domainID, appID, userID string,
	profileData []byte, authorizedKeys []*keyspb.PublicKey,
	vrfProof, oldLeaf []byte) (
	*entry.Mutation, error)

NewMutation creates a Mutation given the userID, desired state, and previous entry.

func (*Verifier) VerifyGetEntryResponse

func (v *Verifier) VerifyGetEntryResponse(ctx context.Context, domainID, appID, userID string,
	trusted *trillian.SignedLogRoot, in *pb.GetEntryResponse) error

VerifyGetEntryResponse verifies GetEntryResponse:

• Verify commitment.
• Verify VRF.
• Verify tree proof.
• Verify signature.
• Verify consistency proof from log.Root().
• Verify inclusion proof.
