Overview

package dns checks if a domain name is aware of a hashed public key. A look-up is performed if the specified domain name matches "^_sigsum_v0.*".

Example

name := "_sigsum_v0.testonly.sigsum.org"
pub := mustDecodePublicKey("cda2517e17dcba133eb0e71bf77473f94a77d7e61b1de4e1e64adfd0938d6182")

timeout := 10 * time.Second
ctx, cancel := context.WithTimeout(context.Background(), timeout)
defer cancel()

dr := NewDefaultResolver()
if err := dr.Verify(ctx, name, pub); err != nil {
	log.Fatal(err.Error())
}

Types

type DefaultResolver

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

DefaultResolver implements the Verifier interface with Go's default resolver

func (*DefaultResolver) Verify

func (dr *DefaultResolver) Verify(ctx context.Context, name string, pub *types.PublicKey) error

type DummyResolver

type DummyResolver struct {
}

func (*DummyResolver) Verify

func (_ *DummyResolver) Verify(_ context.Context, _ string, _ *types.PublicKey) error

type Verifier

type Verifier interface {
	Verify(ctx context.Context, name string, key *types.PublicKey) error
}

Verifier can verify that a domain name is aware of a public key

func NewDefaultResolver

func NewDefaultResolver() Verifier

func NewDummyResolver

func NewDummyResolver() Verifier
