Functions

func CanReadCertOrKey

func CanReadCertOrKey(certPath, keyPath string) bool

CanReadCertOrKey returns true if the certificate or key files already exists, otherwise returns false.

func CertsFromFile

func CertsFromFile(file string) ([]*x509.Certificate, error)

CertsFromFile returns the x509.Certificates contained in the given PEM-encoded file. Returns an error if the file could not be read, a certificate could not be parsed, or if the file does not contain any certificates

func EncodeCertPEM

func EncodeCertPEM(cert *x509.Certificate) []byte

EncodeCertPEM returns PEM-endcoded certificate data

func EncodePrivateKeyPEM

func EncodePrivateKeyPEM(key *rsa.PrivateKey) []byte

EncodePrivateKeyPEM returns PEM-encoded private key data

func EncodePublicKeyPEM

func EncodePublicKeyPEM(key *rsa.PublicKey) ([]byte, error)

EncodePublicKeyPEM returns PEM-endcode public data

func FormatBytesCert

func FormatBytesCert(cert []byte) (string, error)

FormatBytesCert receives byte array certificate and formats in human-readable format

func FormatCert

func FormatCert(c *x509.Certificate) string

FormatCert receives certificate and formats in human-readable format

func GenerateSelfSignedCertKey

func GenerateSelfSignedCertKey(host string, alternateIPs []net.IP, alternateDNS []string) ([]byte, []byte, error)

GenerateSelfSignedCertKey creates a self-signed certificate and key for the given host. Host may be an IP or a DNS name You may also specify additional subject alt names (either ip or dns names) for the certificate

func MakeCSR

func MakeCSR(privateKey interface{}, subject *pkix.Name, dnsSANs []string, ipSANs []net.IP) (csr []byte, err error)

MakeCSR generates a PEM-encoded CSR using the supplied private key, subject, and SANs. All key types that are implemented via crypto.Signer are supported (This includes *rsa.PrivateKey and *ecdsa.PrivateKey.)

func MakeEllipticPrivateKeyPEM

func MakeEllipticPrivateKeyPEM() ([]byte, error)

MakeEllipticPrivateKeyPEM creates an ECDSA private key

func NewPool

func NewPool(filename string) (*x509.CertPool, error)

NewPool returns an x509.CertPool containing the certificates in the given PEM-encoded file. Returns an error if the file could not be read, a certificate could not be parsed, or if the file does not contain any certificates

func NewPrivateKey

func NewPrivateKey() (*rsa.PrivateKey, error)

NewPrivateKey creates an RSA private key

func NewSelfSignedCACert

func NewSelfSignedCACert(cfg Config, key *rsa.PrivateKey) (*x509.Certificate, error)

NewSelfSignedCACert creates a CA certificate

func NewSignedCert

func NewSignedCert(cfg Config, key *rsa.PrivateKey, caCert *x509.Certificate, caKey *rsa.PrivateKey) (*x509.Certificate, error)

NewSignedCert creates a signed certificate using the given CA certificate and key

func ParseCSR

func ParseCSR(obj *certificates.CertificateSigningRequest) (*x509.CertificateRequest, error)

ParseCSR extracts the CSR from the API object and decodes it.

func ParseCertsPEM

func ParseCertsPEM(pemCerts []byte) ([]*x509.Certificate, error)

ParseCertsPEM returns the x509.Certificates contained in the given PEM-encoded byte array Returns an error if a certificate could not be parsed, or if the data does not contain any certificates

func ParsePrivateKeyPEM

func ParsePrivateKeyPEM(keyData []byte) (interface{}, error)

ParsePrivateKeyPEM returns a private key parsed from a PEM block in the supplied data. Recognizes PEM blocks for "EC PRIVATE KEY" and "RSA PRIVATE KEY"

func WriteCert

func WriteCert(certPath string, data []byte) error

WriteCert writes the pem-encoded certificate data to certPath. The certificate file will be created with file mode 0644. If the certificate file already exists, it will be overwritten. The parent directory of the certPath will be created as needed with file mode 0755.

func WriteKey

func WriteKey(keyPath string, data []byte) error

WriteKey writes the pem-encoded key data to keyPath. The key file will be created with file mode 0600. If the key file already exists, it will be overwritten. The parent directory of the keyPath will be created as needed with file mode 0755.

Types

type AltNames

type AltNames struct {
	DNSNames []string
	IPs      []net.IP
}

AltNames contains the domain names and IP addresses that will be added to the API Server's x509 certificate SubAltNames field. The values will be passed directly to the x509.Certificate object.

type Config

type Config struct {
	CommonName   string
	Organization []string
	AltNames     AltNames
}

Config containes the basic fields required for creating a certificate
