Mostly this class is put to together from internet examples, k this class should do some doc, xls, and some picture encryption and then decryption, but problem is like when i decrypt file, in that process decryption misses bytes so file is smaller then original.

Why are you using sun. classes? They are not officially supported and might be altered or even withdrawn in future.
I don't think this is a "beginner's" topic, and I think it would sit better in the security forum, so I shall move it.
