Functions

func ExpiresAt

func ExpiresAt(identityBytes []byte) time.Time

ExpiresAt returns when the given identity expires, or a zero time.Time in case we cannot determine that

func GetRandomBytes

func GetRandomBytes(len int) ([]byte, error)

GetRandomBytes returns len random looking bytes

func GetRandomNonce

func GetRandomNonce() ([]byte, error)

GetRandomNonce returns a random byte array of length NonceSize

func TrackExpiration

func TrackExpiration(tls bool, serverCert []byte, clientCertChain [][]byte, sIDBytes []byte, info MessageFunc, warn MessageFunc, now time.Time, s Scheduler)

TrackExpiration warns a week before one of the certificates expires

Types

type MessageFunc

type MessageFunc func(format string, args ...interface{})

MessageFunc notifies a message happened with the given format, and can be replaced with Warnf or Infof of a logger.

type Scheduler

type Scheduler func(d time.Duration, f func()) *time.Timer

Scheduler invokes f after d time, and can be replaced with time.AfterFunc.
