Method Detail

initialize

public void initialize(int strength,
                       SecureRandom random)

Description copied from class: KeyPairGenerator

Initializes this KeyPairGenerator with the given key size and the given SecureRandom. The default parameter set will be used.

Overrides:

initialize in class KeyPairGenerator

Parameters:

strength - the key size

random - the source of randomness

initialize

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

Description copied from class: KeyPairGenerator

Initializes this KeyPairGenerator with the given AlgorithmParameterSpec and the given SecureRandom.

Overrides:

initialize in class KeyPairGenerator

Parameters:

params - the parameters to use

random - the source of randomness

Throws:

InvalidAlgorithmParameterException - if the specified parameters are not supported

generateKeyPair

public KeyPair generateKeyPair()

Description copied from class: KeyPairGenerator

Computes and returns a new unique KeyPair each time this method is called.

This does exactly the same as KeyPairGenerator.genKeyPair().

Overrides:

generateKeyPair in class KeyPairGenerator

Returns:

a new unique KeyPair each time this method is called

createKeyGenParamsBC

protected ECKeyGenerationParameters createKeyGenParamsBC(ECParameterSpec p,
                                                         SecureRandom r)

createKeyGenParamsJCE

protected ECKeyGenerationParameters createKeyGenParamsJCE(ECParameterSpec p,
                                                          SecureRandom r)

createNamedCurveSpec

protected ECNamedCurveSpec createNamedCurveSpec(String curveName)
                                         throws InvalidAlgorithmParameterException

Throws:

InvalidAlgorithmParameterException

initializeNamedCurve

protected void initializeNamedCurve(String curveName,
                                    SecureRandom random)
                             throws InvalidAlgorithmParameterException

Throws:

InvalidAlgorithmParameterException
