func GenerateRSAPrivateKey 

func GenerateRSAPrivateKey(keySize int) (*rsa.PrivateKey, error)

GenerateRSAPrivateKey will generate a RSA private key of the given size. It places restrictions on the minimum and maximum RSA keysize.

func GenerateTemplate 

func GenerateTemplate(crt *v1.Certificate) (*x509.Certificate, error)

GenerateTemplate will create a x509.Certificate for the given Certificate resource. This should create a Certificate template that is equivalent to the CertificateRequest generated by GenerateCSR. The PublicKey field must be populated by the caller.
