public DHKeyPairGen()

Method Detail

engineInitialize

protected final void engineInitialize(int keysize)
                               throws InvalidAlgorithmParameterException

Do not use this function to initialize dh key generator or InvalidAlgorithmParameterException will be thrown.

Overrides:

engineInitialize in class KeyPairGeneratorSpi

Parameters:

keysize - the keysize. This is an algorithm-specific metric, such as modulus length, specified in number of bits.

Throws:

InvalidAlgorithmParameterException - if the keysize is not supported by this KeyPairGeneratorSpi object.

engineInitialize

protected final void engineInitialize(AlgorithmParameterSpec params)
                               throws InvalidAlgorithmParameterException

Initializes the key pair generator using the specified parameter set.

Overrides:

engineInitialize in class KeyPairGeneratorSpi

Parameters:

params - the parameter set used to generate the keys.

Throws:

InvalidAlgorithmParameterException - if the given parameters are inappropriate for this key pair generator.

engineGenerateKeyPair

protected final KeyPair engineGenerateKeyPair()

Generates a key pair.

Overrides:

engineGenerateKeyPair in class KeyPairGeneratorSpi

Returns:

the newly generated KeyPair

finalize

protected void finalize()

Overrides:

finalize in class java.lang.Object
