Method Detail

init

public void init(AlgorithmParameterSpec params,
                 SecureRandom random)
          throws InvalidAlgorithmParameterException

Initialize the key generator with the given parameters (which have to be an instance of CamelliaKeyGenParameterSpec) and a source of randomness. If the parameters are null, the default parameters are used.

Overrides:

init in class SecretKeyGenerator

Parameters:

params - the parameters

random - the source of randomness

Throws:

InvalidAlgorithmParameterException - if the parameters are not an instance of CamelliaKeyGenParameterSpec.

init

public void init(int keySize,
                 SecureRandom random)

Initialize the key generator with the given key size and source of randomness.

Overrides:

init in class SecretKeyGenerator

Parameters:

keySize - the key size

random - the source of randomness

init

public void init(SecureRandom random)

Initialize the key generator with the default parameters and the given source of randomness.

Overrides:

init in class SecretKeyGenerator

Parameters:

random - the source of randomness

generateKey

public SecretKey generateKey()

Generate a Camellia key.

Overrides:

generateKey in class SecretKeyGenerator

Returns:

the generated CamelliaKey
