My code has been using objects like ECPrivateKey for a long time. With 1.57 I've \
noticed this warning message:

- Access restriction: The type 'ECPrivateKey' is not API (restriction on required \
library '/Library/Java/  Extensions/bcprov-ext-jdk15on-157.jar')


What type should I use instead of, e.g., ECPrivateKey? And may I ask why it is \
deprecated?

Thanks!

P.S. Here's an example of how I use it:

	PKCS8EncodedKeySpec pkcs8KeySpec = new PKCS8EncodedKeySpec(keyBytes);
	KeyFactory kf = KeyFactory.getInstance("EC", "BC");
		
	ECPrivateKey priKey = (ECPrivateKey) kf.generatePrivate(pkcs8KeySpec);

	// decrypt the data
	Cipher cipher =  Cipher.getInstance(ALGORITHM, "BC");
	cipher.init(Cipher.DECRYPT_MODE, priKey, rng);
