```
public BasicEntropySourceProvider(java.security.SecureRandom random,
                                  boolean isPredictionResistant)
```
    Create a entropy source provider based on the passed in SecureRandom.
    
    Parameters:
    
    random - the SecureRandom to base EntropySource construction on.
    
    isPredictionResistant - boolean indicating if the SecureRandom is based on prediction resistant entropy or not (true if it is).

  - get
```
public EntropySource get(int bitsRequired)
```
    Return an entropy source that will create bitsRequired bits of entropy on each invocation of getEntropy().
    
    Specified by:
    
    get in interface EntropySourceProvider
    
    Parameters:
    
    bitsRequired - size (in bits) of entropy to be created by the provided source.
    
    Returns:
    
    an EntropySource that generates bitsRequired bits of entropy on each call to its getEntropy() method.
