var ErrTLSCertExpiresSoon = fmt.Errorf("TLS certificate will expire soon")

ErrTLSCertExpiresSoon is returned when the TLS certificate is about to expire.

var GenerateCert = func(template *x509.Certificate) ([]byte, []byte, error) {
	priv, err := rsa.GenerateKey(rand.Reader, 2048)
	if err != nil {

}

GenerateCert generates a new TLS certificate and returns it as PEM.
