```
public byte[] getIV()
```
    Return a copy of the current IV value.
    
    Specified by:
    
    getIV in interface ParametersWithIV<T extends GeneralParameters>
    
    Returns:
    
    the current IV.
  - withIV
```
public T withIV(java.security.SecureRandom random)
```
    Return an implementation of our parameterized type with an IV constructed from the passed in SecureRandom.
    
    Specified by:
    
    withIV in interface ParametersWithIV<T extends GeneralParameters>
    
    Parameters:
    
    random - the SecureRandom to use as the source of IV data.
    
    Returns:
    
    a new instance of our parameterized type with a new IV.
  - withIV
```
public T withIV(byte[] iv)
```
    Return an implementation of our parameterized type containing the passed in IV.
    
    Specified by:
    
    withIV in interface ParametersWithIV<T extends GeneralParameters>
    
    Parameters:
    
    iv - the bytes making up the iv, or nonce, to use.
    
    Returns:
    
    a new instance of our parameterized type with a new IV.
