Functions

func ClusterName

func ClusterName(subject pkix.Name) (string, error)

ClusterName returns cluster name from organization

func GenerateSelfSignedCA

func GenerateSelfSignedCA(entity pkix.Name, dnsNames []string, ttl time.Duration) ([]byte, []byte, error)

GenerateSelfSignedCA generates self-signed certificate authority used for internal inter-node communications

func GenerateSelfSignedCAWithPrivateKey

func GenerateSelfSignedCAWithPrivateKey(priv *rsa.PrivateKey, entity pkix.Name, dnsNames []string, ttl time.Duration) ([]byte, []byte, error)

GenerateSelfSignedCA generates self-signed certificate authority used for internal inter-node communications

func MarshalCertificatePEM

func MarshalCertificatePEM(cert *x509.Certificate) ([]byte, error)

MarshalCertificatePEM takes a *x509.Certificate and returns the PEM encoded bytes.

func MarshalPublicKeyFromPrivateKeyPEM

func MarshalPublicKeyFromPrivateKeyPEM(privateKey crypto.PrivateKey) ([]byte, error)

MarshalPublicKeyFromPrivateKeyPEM extracts public key from private key and returns PEM marshalled key

func ParseCertificatePEM

func ParseCertificatePEM(bytes []byte) (*x509.Certificate, error)

ParseCertificatePEM parses PEM-encoded certificate

func ParseCertificateRequestPEM

func ParseCertificateRequestPEM(bytes []byte) (*x509.CertificateRequest, error)

ParseCertificateRequestPEM parses PEM-encoded certificate signing request

func ParsePrivateKeyDER

func ParsePrivateKeyDER(der []byte) (crypto.Signer, error)

ParsePrivateKeyDER parses unencrypted DER-encoded private key

func ParsePrivateKeyPEM

func ParsePrivateKeyPEM(bytes []byte) (crypto.Signer, error)

ParsePrivateKeyPEM parses PEM-encoded private key

func ParsePublicKeyDER

func ParsePublicKeyDER(der []byte) (crypto.PublicKey, error)

ParsePublicKeyDER parses unencrypted DER-encoded publice key

func ParsePublicKeyPEM

func ParsePublicKeyPEM(bytes []byte) (interface{}, error)

ParsePublicKeyPEM parses public key PEM

Types

type CertAuthority

type CertAuthority struct {
	// Cert is a CA certificate
	Cert *x509.Certificate
	// Signer is a private key based signer
	Signer crypto.Signer
}

CertAuthority is X.509 certificate authority

func New

func New(certPEM, keyPEM []byte) (*CertAuthority, error)

New returns new CA from PEM encoded certificate and private key. Private Key is optional, if omitted CA won't be able to issue new certificates, only verify them

func (*CertAuthority) GenerateCertificate

func (ca *CertAuthority) GenerateCertificate(req CertificateRequest) ([]byte, error)

GenerateCertificate generates certificate from request

type CertificateRequest

type CertificateRequest struct {
	// Clock is a clock used to get current or test time
	Clock clockwork.Clock
	// PublicKey is a public key to sign
	PublicKey crypto.PublicKey
	// Subject is a subject to include in certificate
	Subject pkix.Name
	// NotAfter is a time after which the issued certificate
	// will be no longer valid
	NotAfter time.Time
	// DNSNames is a list of DNS names to add to certificate
	DNSNames []string
}

CertificateRequest is a X.509 signing certificate request

func (*CertificateRequest) CheckAndSetDefaults

func (c *CertificateRequest) CheckAndSetDefaults() error

CheckAndSetDefaults checks and sets default values

type Identity

type Identity struct {
	// Username is a username or name of the node connection
	Username string
	// Groups is a list of groups (Teleport roles) encoded in the identity
	Groups []string
	// Usage is a list of usage restrictions encoded in the identity
	Usage []string
	// Principals is a list of Unix logins allowed.
	Principals []string
	// KubernetesGroups is a list of Kubernetes groups allowed
	KubernetesGroups []string
	// KubernetesUsers is a list of Kubernetes users allowed
	KubernetesUsers []string
	// Expires specifies whenever the session will expire
	Expires time.Time
	// RouteToCluster specifies the target cluster
	// if present in the session
	RouteToCluster string
	// Traits hold claim data used to populate a role at runtime.
	Traits wrappers.Traits
}

Identity is an identity of the user or service, e.g. Proxy or Node

func FromSubject

func FromSubject(subject pkix.Name, expires time.Time) (*Identity, error)

FromSubject returns identity from subject name

func (*Identity) CheckAndSetDefaults

func (i *Identity) CheckAndSetDefaults() error

CheckAndSetDefaults checks and sets default values

func (*Identity) Subject

func (id *Identity) Subject() (pkix.Name, error)

Subject converts identity to X.509 subject name
