func CertOrKeyExist 

func CertOrKeyExist(pkiPath, name string) bool

CertOrKeyExist returns a boolean whether the cert or the key exists

func CertificateRequestFromFile 

func CertificateRequestFromFile(file string) (*x509.CertificateRequest, error)

CertificateRequestFromFile returns the CertificateRequest from a given PEM-encoded file. Returns an error if the file could not be read or if the CSR could not be parsed.

EncodeCertPEM returns PEM-endcoded certificate data

func EncodePublicKeyPEM added in v1.14.0 

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

EncodePublicKeyPEM returns PEM-encoded public data

func GeneratePrivateKey added in v1.21.0 

func GeneratePrivateKey(keyType kubeadmapi.EncryptionAlgorithmType) (crypto.Signer, error)

GeneratePrivateKey is the default function for generating private keys.

func GetAPIServerAltNames 

func GetAPIServerAltNames(cfg *kubeadmapi.InitConfiguration) (*certutil.AltNames, error)

GetAPIServerAltNames builds an AltNames object for to be used when generating apiserver certificate

func GetEtcdAltNames 

func GetEtcdAltNames(cfg *kubeadmapi.InitConfiguration) (*certutil.AltNames, error)

GetEtcdAltNames builds an AltNames object for generating the etcd server certificate. `advertise address` and localhost are included in the SAN since this is the interfaces the etcd static pod listens on. The user can override the listen address with `Etcd.ExtraArgs` and add SANs with `Etcd.ServerCertSANs`.

func GetEtcdPeerAltNames 

func GetEtcdPeerAltNames(cfg *kubeadmapi.InitConfiguration) (*certutil.AltNames, error)

GetEtcdPeerAltNames builds an AltNames object for generating the etcd peer certificate. Hostname and `API.AdvertiseAddress` are included if the user chooses to promote the single node etcd cluster into a multi-node one (stacked etcd). The user can override the listen address with `Etcd.ExtraArgs` and add SANs with `Etcd.PeerCertSANs`.

func HasServerAuth 

func HasServerAuth(cert *x509.Certificate) bool

HasServerAuth returns true if the given certificate is a ServerAuth

func NewCSR 

func NewCSR(cfg CertConfig, key crypto.Signer) (*x509.CertificateRequest, error)

NewCSR creates a new CSR

func NewCSRAndKey 

func NewCSRAndKey(config *CertConfig) (*x509.CertificateRequest, crypto.Signer, error)

NewCSRAndKey generates a new key and CSR and that could be signed to create the given certificate

func NewCertAndKey 

func NewCertAndKey(caCert *x509.Certificate, caKey crypto.Signer, config *CertConfig) (*x509.Certificate, crypto.Signer, error)

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

func NewCertificateAuthority 

func NewCertificateAuthority(config *CertConfig) (*x509.Certificate, crypto.Signer, error)

NewCertificateAuthority creates new certificate and private key for the certificate authority

func NewIntermediateCertificateAuthority added in v1.21.0 

func NewIntermediateCertificateAuthority(parentCert *x509.Certificate, parentKey crypto.Signer, config *CertConfig) (*x509.Certificate, crypto.Signer, error)

NewIntermediateCertificateAuthority creates new certificate and private key for an intermediate certificate authority

func NewSelfSignedCACert added in v1.31.0 

func NewSelfSignedCACert(cfg *CertConfig, key crypto.Signer) (*x509.Certificate, error)

NewSelfSignedCACert creates a new self-signed CA certificate

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

func PathsForCertAndKey 

func PathsForCertAndKey(pkiPath, name string) (string, string)

PathsForCertAndKey returns the paths for the certificate and key given the path and basename.
