Readin from a file. and storing the information. (read inside)

Code:

---

        public void encryptFile(String fileName) {
                try {
                        String inputFile = fileName+".java";
                        File file = new File(inputFile);
                        int fileLength = (int)file.length();
                        byte fileBytes[] = new byte[fileLength];
                       
                        DataInputStream dos = new DataInputStream(new BufferedInputStream(new FileInputStream(inputFile)));
                        dos.readFully(fileBytes, 0, fileLength);
                        dos.close();
                       
                        File Name = new File(inputFile);
                        Name.delete();

                        for(int currentByte = 0; currentByte < fileBytes.length; currentByte++)
                                fileBytes[currentByte] = (byte)(~fileBytes[currentByte]);
                               
                        FileOutputStream encryptedFile = new FileOutputStream(fileName+".txt");
                        encryptedFile.write(fileBytes);
                        encryptedFile.close();
                } catch(Exception ex) { ex.printStackTrace(); }
        }

Hello. I am using the above code (^^) to encrypt my .java files to .txt files and delete the .java ones, so they go from example:

Code:

---

import javax.swing.JFrame;

public class File1 {
        static JFrame frame = new JFrame();
}

---

too

Code:

---

–’���‹ß•ž‰ž‡ÑŒˆ–‘˜Ñµ¹�ž’šÄòõòõ�Š�“–œßœ“žŒŒß¹–“šÎß„òõöŒ‹ž‹–œßµ¹�ž’šß™�ž’šßÂß‘šˆßµ¹�ž’š×ÖÄòõ‚òõ

(i actually encrypted it.)

now i ned to be able to read from this by doing something like

(this wont work)

Code:

---

[add unencryptin code here.]
File Frame = new File(File1);

---

so i can now do.

Code:

---

Frame.frame.setVisible(true);

---

and thus letting me read my files with out storing it in .java so my code cannot be leeched or something.

thank-you for your help.

Your encryption code is a (very weak) two way encryption because all you do is flip every bit in the data. Apply the same code again to the encrypted data and voila, you'll have your original data back.

kind regards,

why would you encrypt java files?
normally you only distrebute a class file whitch is already encrypted?
