Types

type CertificateAuthority

type CertificateAuthority struct {
	Certificate *x509.Certificate
	PrivateKey  crypto.Signer
	Backdate    time.Duration
	Now         func() time.Time
}

CertificateAuthority implements a certificate authority that supports policy based signing. It's used by the signing controller.

func (*CertificateAuthority) Sign

func (ca *CertificateAuthority) Sign(crDER []byte, policy SigningPolicy) ([]byte, error)

Sign signs a certificate request, applying a SigningPolicy and returns a DER encoded x509 certificate.

type PermissiveSigningPolicy

type PermissiveSigningPolicy struct {
	// TTL is the certificate TTL. It's used to calculate the NotAfter value of
	// the certificate.
	TTL time.Duration
	// Usages are the allowed usages of a certficate.
	Usages []capi.KeyUsage
}

PermissiveSigningPolicy is the signing policy historically used by the local signer.

• It forwards all SANs from the original signing request.
• It sets allowed usages as configured in the policy.
• It sets NotAfter based on the TTL configured in the policy.
• It zeros all extensions.
• It sets BasicConstraints to true.
• It sets IsCA to false.

type SigningPolicy

type SigningPolicy interface {
	// contains filtered or unexported methods
}

SigningPolicy validates a CertificateRequest before it's signed by the CertificateAuthority. It may default or otherwise mutate a certificate template.
