All Implemented Interfaces:

Closeable, Flushable, AutoCloseable
```
public class RFileCipherOutputStream
extends CipherOutputStream
```
This class extends CipherOutputStream to include a way to track the number of bytes that have been encrypted by the stream. The write method also includes a mechanism to stop writing and throw an exception if exceeding a maximum number of bytes is attempted.

public void write(byte[] b,
                  int off,
                  int len)
           throws IOException
```
    Override of CipherOutputStream's write to count the number of bytes that have been encrypted. This method now throws an exception if an attempt to write bytes beyond a maximum is made.
    
    Overrides:
    
    write in class CipherOutputStream
    
    Throws:
    
    IOException

```
public void write(int b)
