Functions ¶

func CancelWhenSignaled ¶

func CancelWhenSignaled(parent context.Context) context.Context

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 CheckInstall ¶

func CheckInstall()

func DoCmd ¶

func DoCmd(cmd string, args ...string)

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 GetCopyright ¶

func GetCopyright(file string) string

func GetDomain ¶

func GetDomain() string

func GetRepo ¶

func GetRepo() string

func LoadRepoFromGoMod ¶

func LoadRepoFromGoMod() error

func LoadRepoFromGoPath ¶

func LoadRepoFromGoPath() error

func LoadRepoFromGoPathOrGoMod ¶

func LoadRepoFromGoPathOrGoMod() error

func NewCertAndKey ¶

func NewCertAndKey(caCert *x509.Certificate, caKey *rsa.PrivateKey, config Config) (*x509.Certificate, *rsa.PrivateKey, error)

NewCertAndKey creates new certificate and key by passing the certificate authority certificate and key

func NewPrivateKey ¶

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

NewPrivateKey creates an RSA private key

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 Overwrite ¶

func Overwrite(path, templateName, templateValue string, data interface{}) bool

Overwrite always updates the target file with the new content.

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", "RSA PRIVATE KEY", or "PRIVATE KEY"

func PrivateKeyFromFile ¶

func PrivateKeyFromFile(file string) (interface{}, error)

PrivateKeyFromFile returns the private key in rsa.PrivateKey or ecdsa.PrivateKey format from a given PEM-encoded file. Returns an error if the file could not be read or if the private key could not be parsed.

func SetRepo ¶

func SetRepo(r string)

func TryLoadCertAndKeyFromDisk ¶

func TryLoadCertAndKeyFromDisk(pkiPath, name string) (*x509.Certificate, *rsa.PrivateKey, error)

TryLoadCertAndKeyFromDisk tries to load a cert and a key from the disk and validates that they are valid

func TryLoadCertFromDisk ¶

func TryLoadCertFromDisk(pkiPath, name string) (*x509.Certificate, error)

TryLoadCertFromDisk tries to load the cert from the disk and validates that it is valid

func TryLoadKeyFromDisk ¶

func TryLoadKeyFromDisk(pkiPath, name string) (*rsa.PrivateKey, error)

TryLoadKeyFromDisk tries to load the key from the disk and validates that it is valid

func Untar ¶

func Untar(r io.Reader, dir string, renderFunc map[string]func(reader io.Reader) io.Reader) error

Untar reads the gzip-compressed tar file from r and writes it into dir.

func WriteIfNotFound ¶

func WriteIfNotFound(path, templateName, templateValue string, data interface{}) bool

writeIfNotFound returns true if the file was created and false if it already exists

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
	Usages       []x509.ExtKeyUsage
}

Config containes the basic fields required for creating a certificate
