deriveKey abstract method
Generates a new secret key from a secret key and a nonce.
The nonce ("salt") should be some random sequence of bytes. Nonce does not need to be protected. If possible, you should have a different nonce for each key derivation.
Implementation
@override
Future<SecretKeyData> deriveKey({
required SecretKey secretKey,
List<int> nonce = const <int>[],
List<int> info = const <int>[],
});
