type CA struct {
	Config *TLSCertificateConfig

	SerialGenerator SerialGenerator
}

func EnsureCA 

func EnsureCA(certFile, keyFile, serialFile, name string, expireDays int) (*CA, bool, error)

EnsureCA returns a CA, whether it was created (as opposed to pre-existing), and any error if serialFile is empty, a RandomSerialGenerator will be used

func GetCA 

func GetCA(certFile, keyFile, serialFile string) (*CA, error)

if serialFile is empty, a RandomSerialGenerator will be used

func GetCAFromBytes 

func GetCAFromBytes(certBytes, keyBytes []byte) (*CA, error)

func MakeSelfSignedCA 

func MakeSelfSignedCA(certFile, keyFile, serialFile, name string, expireDays int) (*CA, error)

if serialFile is empty, a RandomSerialGenerator will be used

func (*CA) EnsureClientCertificate 

func (ca *CA) EnsureClientCertificate(certFile, keyFile string, u user.Info, expireDays int) (*TLSCertificateConfig, bool, error)

func (*CA) EnsureServerCert 

func (ca *CA) EnsureServerCert(certFile, keyFile string, hostnames sets.String, expireDays int) (*TLSCertificateConfig, bool, error)

func (*CA) MakeAndWriteServerCert 

func (ca *CA) MakeAndWriteServerCert(certFile, keyFile string, hostnames sets.String, expireDays int) (*TLSCertificateConfig, error)

func (*CA) MakeClientCertificate 

func (ca *CA) MakeClientCertificate(certFile, keyFile string, u user.Info, expireDays int) (*TLSCertificateConfig, error)

func (*CA) MakeClientCertificateForDuration 

func (ca *CA) MakeClientCertificateForDuration(u user.Info, lifetime time.Duration) (*TLSCertificateConfig, error)

func (ca *CA) MakeServerCert(hostnames sets.String, expireDays int, fns ...CertificateExtensionFunc) (*TLSCertificateConfig, error)

func (*CA) MakeServerCertForDuration 

func (ca *CA) MakeServerCertForDuration(hostnames sets.String, lifetime time.Duration, fns ...CertificateExtensionFunc) (*TLSCertificateConfig, error)

type CertificateExtensionFunc 

type CertificateExtensionFunc func(*x509.Certificate) error

CertificateExtensionFunc is passed a certificate that it may extend, or return an error if the extension attempt failed.

type RandomSerialGenerator 

type RandomSerialGenerator struct {
}

RandomSerialGenerator returns a serial based on time.Now and the subject

func (*RandomSerialGenerator) Next 

func (s *RandomSerialGenerator) Next(template *x509.Certificate) (int64, error)

type SerialFileGenerator 

type SerialFileGenerator struct {
	SerialFile string

	Serial int64
	// contains filtered or unexported fields
}

SerialFileGenerator returns a unique, monotonically increasing serial number and ensures the CA on disk records that value.

func NewSerialFileGenerator 

func NewSerialFileGenerator(serialFile string) (*SerialFileGenerator, error)

func (*SerialFileGenerator) Next 

func (s *SerialFileGenerator) Next(template *x509.Certificate) (int64, error)

Next returns a unique, monotonically increasing serial number and ensures the CA on disk records that value.

type SerialGenerator 

type SerialGenerator interface {
	Next(template *x509.Certificate) (int64, error)
}

SerialGenerator is an interface for getting a serial number for the cert. It MUST be thread-safe.
