  - init
```
public void init(int size,
                 int certainty,
                 java.security.SecureRandom random)
```
    initialise the key generator.
    
    Parameters:
    
    size - size of the key (range 2^512 -> 2^1024 - 64 bit increments)
    
    certainty - measure of robustness of prime (for FIPS 186-2 compliance this should be at least 80).
    
    random - random byte source.
  - init
```
public void init(DSAParameterGenerationParameters params)
```
    Initialise the key generator for DSA 2.
    Use this init method if you need to generate parameters for DSA 2 keys.
    
    Parameters:
    
    params - DSA 2 key generation parameters.
  - generateParameters
```
public DSAParameters generateParameters()
```
    which generates the p and g values from the given parameters, returning the DSAParameters object.
    Note: can take a while...
    
    Returns:
    
    a generated DSA parameters object.
