public abstract class AndroidKeyStoreKeyPairGeneratorSpi extends KeyPairGeneratorSpi
KeyStore.getInstance(String)
using the
"AndroidKeyStore"
type.
This class can not be directly instantiated and must instead be used via the
KeyPairGenerator.getInstance("AndroidKeyStore")
API.

void |
initialize(AlgorithmParameterSpec params,
SecureRandom random)
Initializes the key pair generator using the specified parameter
set and user-provided source of randomness.

KeyPairGeneratorSpi
This concrete method has been added to this previously-defined abstract class. (For backwards compatibility, it cannot be abstract.) It may be overridden by a provider to initialize the key pair generator. Such an override is expected to throw an InvalidAlgorithmParameterException if a parameter is inappropriate for this key pair generator. If this method is not overridden, it always throws an UnsupportedOperationException.
