```
protected abstract void engineInit(AlgorithmParameterSpec genParamSpec,
                                   SecureRandom random)
                            throws InvalidAlgorithmParameterException
```
    Initializes this AlgorithmParameterGeneratorSpi with the given AlgorithmParameterSpec and the given SecureRandom.
    
    Parameters:
    
    genParamSpec - the parameters to use.
    
    random - the source of randomness.
    
    Throws:
    
    InvalidAlgorithmParameterException - if the specified parameters are not supported.
