Functions

func FlagSet 

func FlagSet() *pflag.FlagSet

FlagSet contains flags relevant for JSON-LD

func SetNewDenylistWithCert 

func SetNewDenylistWithCert(t *testing.T, val Validator, cert *x509.Certificate)

SetNewDenylistWithCert sets a new Denylist on the Validator and adds the certificate. This is useful in integrations tests etc.

Types

type Config 

type Config struct {
	// Denylist specifies config options for the PKI denylist, which acts as a global CRL
	Denylist DenylistConfig `koanf:"denylist"`

	// MaxUpdateFailHours specifies the maximum number of hours that a denylist update can fail
	MaxUpdateFailHours int `koanf:"maxupdatefailhours"`

	// Softfail still accepts connections if the revocation status of a certificate cannot be reliably established if set to true
	Softfail bool `koanf:"softfail"`
}

Config specifies configuration parameters for PKI functionality

func DefaultConfig 

func DefaultConfig() Config

func TestConfig 

func TestConfig(t *testing.T) Config

type Provider 

type Provider interface {
	Validator
	// CreateTLSConfig creates a tls.Config from the core.TLSConfig for outbound connections.
	// It returns (nil, nil)  if core.TLSConfig.Enabled() == false.
	CreateTLSConfig(cfg core.TLSConfig) (*tls.Config, error)
}

Provider is an interface for providing PKI services (e.g. TLS configuration, certificate validation).

type Validator 

type Validator interface {
	// CheckCRL returns an error if any of the certificates in the chain has been revoked, or if the request cannot be processed.
	// All certificates in the chain are considered trusted, which means that the caller has verified the integrity of the chain and appropriateness for the use-case.
	// Any new CA / CRL in the chain will be added to the internal watchlist and updated periodically, so it MUST NOT be called on untrusted/invalid chains.
	// The certificate chain MUST be sorted leaf to root.
	//
	// ErrCertRevoked and ErrUnknownIssuer indicate that at least one of the certificates is revoked, or signed by an unknown CA (so we have no key to verify the CRL).
	// ErrCRLMissing and ErrCRLExpired signal that at least one of the certificates cannot be validated reliably.
	// If the certificate was revoked on an expired CRL, it wil return ErrCertRevoked.
	//
	// CheckCRL uses the configured soft-/hard-fail strategy
	// If set to soft-fail it ignores ErrCRLMissing and ErrCRLExpired errors.
	CheckCRL(chain []*x509.Certificate) error

	// CheckCRLStrict does the same as CheckCRL, except it always uses the hard-fail strategy.
	CheckCRLStrict(chain []*x509.Certificate) error

	// SetVerifyPeerCertificateFunc sets config.ValidatePeerCertificate to use CheckCRL.
	SetVerifyPeerCertificateFunc(config *tls.Config) error

	// SubscribeDenied registers a callback that is triggered everytime the denylist is updated.
	// This can be used to revalidate all certificates on long-lasting connections by calling CheckCRL on them again.
	SubscribeDenied(f func())
}

Validator is used to check the revocation status of certificates on the issuer controlled CRL and the user controlled Denylist. It does NOT manage trust and assumes all presented certificates belong to a trusted certificate tree.
