Functions

func DecodeJwtPart

func DecodeJwtPart(seg string) ([]byte, error)

func ExtractJwtAud

func ExtractJwtAud(jwt string) ([]string, bool)

ExtractJwtAud extracts the audiences from a JWT token. If aud cannot be parse, the bool will be set to false. This distinguishes aud=[] from not parsed.

func GetAud

func GetAud(token string) ([]string, error)

GetAud returns the claim `aud` from the token. Returns nil if not found.

func GetExp

func GetExp(token string) (time.Time, error)

GetExp returns token expiration time, or error on failures.

Types

type CertUtil

type CertUtil interface {
	// GetWaitTime returns the waiting time before renewing the certificate.
	GetWaitTime([]byte, time.Time) (time.Duration, error)
}

CertUtil is an interface for utility functions on certificate.

type CertUtilImpl

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

CertUtilImpl is the implementation of CertUtil, for production use.

func NewCertUtil

func NewCertUtil(gracePeriodPercentage int) CertUtilImpl

NewCertUtil returns a new CertUtilImpl

func (CertUtilImpl) GetWaitTime

func (cu CertUtilImpl) GetWaitTime(certBytes []byte, now time.Time) (time.Duration, error)

GetWaitTime returns the waiting time before renewing the cert, based on current time, the timestamps in cert and grace period.
