  - initialize
```
public abstract void initialize(int keysize,
                                SecureRandom random)
```
    Initializes this KeyPairGeneratorSpi with the given key size and the given SecureRandom. The default parameter set will be used.
    
    Parameters:
    
    keysize - the key size (number of bits).
    
    random - the source of randomness.
  - initialize
```
public void initialize(AlgorithmParameterSpec params,
                       SecureRandom random)
                throws InvalidAlgorithmParameterException
```
    Initializes this KeyPairGeneratorSpi with the given AlgorithmParameterSpec and the given SecureRandom.
    
    Parameters:
    
    params - the parameters to use.
    
    random - the source of randomness.
    
    Throws:
    
    InvalidAlgorithmParameterException - if the specified parameters are not supported.
