Functions

func CertificateFromPEMBytes

func CertificateFromPEMBytes(pemBytes []byte) (*x509.Certificate, error)

CertificateFromPEMBytes returns an X.509 certificate from its supplied PEM representation.

func GenerateCSR

func GenerateCSR(signer crypto.Signer, opts CSROptions) (csrPEM []byte, err error)

GenerateCSR generates a CSR using the supplied key, common name and options.

func GenerateKeyAndCSR

func GenerateKeyAndCSR(opts CSROptions) (keyPEM, csrPEM []byte, err error)

GenerateKeyAndCSR generates a private key and returns the key and CSR PEMs.

func MarshalSANs

func MarshalSANs(sans SubjectAlternateNames) (pkix.Extension, error)

func PublicKeyFromPEMBytes

func PublicKeyFromPEMBytes(pemBytes []byte) (crypto.PublicKey, error)

PublicKeyFromPEMBytes returns a public key from its supplied PEM representation.

Types

type CSROptions

type CSROptions struct {
	Subject pkix.Name
	SANs    SubjectAlternateNames
}

CSROptions has optional config for creating a CSR request

type KeyType

type KeyType int

KeyType is the type of private key.

const (
	RSA KeyType
	ECDSA
)

supported key types

func PrivateKeyFromPEMBytes

func PrivateKeyFromPEMBytes(privatePEMBytes []byte) (KeyType, crypto.Signer, error)

PrivateKeyFromPEMBytes returns a private key along with its type from its supplied PEM representation.

type SubjectAlternateNames

type SubjectAlternateNames struct {
	DNSNames       []string
	IPAddresses    []net.IP
	URIs           []url.URL
	EmailAddresses []string
}

SubjectAlternateNames contains the SAN entities in a cert.

func UnmarshalSANs

func UnmarshalSANs(extensions []pkix.Extension) (sans SubjectAlternateNames, err error)

func (*SubjectAlternateNames) IsEmpty

func (s *SubjectAlternateNames) IsEmpty() bool

func (SubjectAlternateNames) String

func (s SubjectAlternateNames) String() string

type Writer

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

Writer writes multiple files with modified suffixes and renames all of them to their final names on save.

func NewWriter

func NewWriter() *Writer

NewWriter returns a writer.

func (*Writer) AddBytes

func (w *Writer) AddBytes(target string, perms os.FileMode, content []byte) error

AddBytes writes a file with the supplied bytes.

func (*Writer) AddFile

func (w *Writer) AddFile(target string, perms os.FileMode, source string) error

AddFile writes a file using the supplied file as source.

func (*Writer) AddReader

func (w *Writer) AddReader(target string, perms os.FileMode, content io.Reader) error

AddReader writes a file using the supplied reader as source.

func (*Writer) Save

func (w *Writer) Save() error

Save renames all temp files written to their final names. When multiple files are involved, this reduces race conditions with inconsistent data but does not completely eliminate it.
