Method Detail

init

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

Initialize the key generator with the given parameters and 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 null not an instance of RC5KeyGenParameterSpec.

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 in bytes

random - the source of randomness

init

public void init(SecureRandom random)

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

Overrides:

init in class SecretKeyGenerator

Parameters:

random - the source of randomness

generateKey

public SecretKey generateKey()

Generate an RC5 key.

Overrides:

generateKey in class SecretKeyGenerator

Returns:

the generated RC5Key
