Method Detail

• finish

  protected void finish()
                 throws IOException

  Description copied from class: CipherOutputStream
  Finishes and voids this cipher output stream. Calling this method causes all remaining buffered bytes to get written and padding to get added if necessary.

  Note that after a call to this method only CipherOutputStream.close() may get called on this cipher output stream The result of calling any other method (including this one) is undefined!

  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
