public AbstractAsymmetricKeyCreator(KeyFactory keyFactory,
                                    int keyLength,
                                    SecurityProvider provider,
                                    RandomFactory randomFactory)
```
    The constructor.
    
    Parameters:
    
    keyFactory - the KeyFactory.
    
    keyLength - the key length.
    
    provider - the security Provider.
    
    randomFactory - the RandomFactory.

  - getKeyLength
```
public int getKeyLength()
```
    Specified by:
    
    getKeyLength in interface KeyCreator
    
    Returns:
    
    the length of the key in bits. The bigger the key length the stronger and more secure the encryption but also the more computation power is required. Reasonable values depend on the algorithm: A recent value for RSA is 4096 bits while for PBKDF2 256 may be sufficient.

protected void register(AsymmetricKeyPairFactory<PR,PU,PAIR> factory)
```
    Please register in proper order of trials for auto-detection.
    
    Parameters:
    
    factory - the AsymmetricKeyPairFactory to register.
  - register
```
protected void register(AsymmetricKeyPairFactory<PR,PU,PAIR> factory,
