  - getUpdatedPrivateKey
```
AsymmetricKeyParameter getUpdatedPrivateKey()
```
    Return the current version of the private key with the updated state.
    Note: calling this method will effectively disable the Signer from being used for further signature generation without another call to init().
    
    Returns:
    
    an updated private key object, which can be used for later signature generation.
