Getting all the bytes in a file

**Proshitness** · 06-15-2012, 08:54 PM

When working on an encrypter I did this:

Java Code:

InputStream in = null;
				byte[] data = null;
				if (f != null) {
					in = new FileInputStream(f);
				} else {
					in = new FileInputStream(iD.getText().toString());
				}
				KeyGenerator keygen = KeyGenerator.getInstance("AES");
				SecretKey key = keygen.generateKey();
				data = new byte[(int)f.length()];
				in.read(data);
				Cipher c = Cipher.getInstance("AES/ECB/PKCS5Padding");
				c.init(mode, key);
				byte[] eData = c.doFinal(data);
				FileOutputStream t = new FileOutputStream(new File(getOutputFile()));
				t.write(eData);
				t.close();
				System.out.println(eData);
				if (in != null)
					in.close();

my problem is that the new line aren't there, I just get one line instead of the number of line that my file was, how can I make it so that It won't leave out the new lines?

There are no "lines" in a file that is read as bytes. If you want lines, you need to read the file's contents as characters with a method that recognizes the lineend character as the end of a line.
The lineend character is just another byte in the file's bytes.

ok, my problem with that is that with a cipher the "doFinal" method can only be used with a byte[] so if I do this instead will it work:
lets say I give a file in the end of each line this char: '~' and in the code i look for that char in the line and if it is found I just add a '\n' in the output file
will that work?

What is in the output file? Is it text or bytes? If it's text for humans to read, then adding the '\n' should be OK.
Why do you want to change the bytes in a file of bytes by adding a '\n'? Can the bytes in the file already have the '\n' character output by the doFinal() method?

What is the problem you are trying to solve?

First off you can see its not divided to a couple of line like the input is, and that is a problem for me.. =\
