Provider p11s = getPkcs11Provider();
PrivateKey sk =
KeyPairGenerator.getInstance("EC").generateKeyPair().getPrivate();
String pem = PEMEncoder.of().encodeToString(sk);
PrivateKey sk2 = (PrivateKey)
PEMDecoder.of().withFactoryFrom(p11s).decode(pem);
System.out.println(sk2 instanceof ECPrivateKey); // shows "false"
