  • getAlgorithm

    public String getAlgorithm()

    Description copied from class: KeyPairGenerator
    Returns the name of the algorithm of this KeyPairGenerator.

    Overrides:

    getAlgorithm in class KeyPairGenerator

    Returns:

    the name of the algorithm of this KeyPairGenerator

  • getResAlgorithm

    public static final String getResAlgorithm()

  • initialize

    public void initialize(int keysize,
                  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:

    keysize - the key size

    random - the source of randomness

  • 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

  • initialize

    public void initialize(AlgorithmParameterSpec param,
                  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:

    param - the parameters to use

    random - the source of randomness

    Throws:

    InvalidAlgorithmParameterException - if the specified parameters are not supported
