Method Detail

• finish

  protected void finish()
                 throws IOException

  Description copied from class: CipherOutputStream
  Finishes this stream and resets it to it's initial state. Calling this method causes all remaining buffered bytes to be written, padding to be added if necessary and the underlying output stream to get flushed.

  Please note that subsequent calls to any write operations after this method may cause an error in the output data if padding is used!

  Overrides:

  finish in class CipherOutputStream

  Throws:

  IOException - If out or cipher aren't properly initialized, the stream has been closed, an I/O error occured the cipher text is invalid, i.e. required padding information is missing.

• paranoidWipe

  private void paranoidWipe(byte[] passwd)

  Wipe the given array.

• writePasswordVerifier

  private void writePasswordVerifier(KeyParameter keyParam)
                              throws IOException

  Throws:

  IOException
