Method Detail

engineInit

protected void engineInit(SecureRandom random)

Initializes this key generator.

Specified by:

engineInit in class KeyGeneratorSpi

Parameters:

random - the source of randomness for this generator

engineInit

protected void engineInit(AlgorithmParameterSpec params,
                          SecureRandom random)
                   throws InvalidAlgorithmParameterException

Initializes this key generator with the specified parameter set and a user-provided source of randomness.

Specified by:

engineInit in class KeyGeneratorSpi

Parameters:

params - the key generation parameters

random - the source of randomness for this key generator

Throws:

InvalidAlgorithmParameterException - if params is inappropriate for this key generator

engineInit

protected void engineInit(int keysize,
                          SecureRandom random)

Initializes this key generator for a certain keysize, using the given source of randomness.

Specified by:

engineInit in class KeyGeneratorSpi

Parameters:

keysize - the keysize. This is an algorithm-specific metric specified in number of bits.

random - the source of randomness for this key generator

engineGenerateKey

protected SecretKey engineGenerateKey()

Generates the DES key.

Specified by:

engineGenerateKey in class KeyGeneratorSpi

Returns:

the new DES key
