Algorithm AES And Algorithm Twofish

Question

I have a project to make an encryption and decryption for string input in java. I've been stucked for a week doing some research in it. I really appreciate if you have sample source code or function method for Algorithm AES and Algorithm Twofish in java that I may use in my project. I really need your help ... hope someone out there could be my savior. Thanks very much.

You need to show what you have written, explain your difficulties, give example input and output and many more things than just ask for a complete solution. Stack Overflow is not a free coding service or a debugging tool. It is expected that you put many times more effort into a question than one might to offer a solution. — indivisible, Jul 10 '14 at 05:25

For AES you can use java's libraries.

The fallowing code will give you an idea to start.

import java.security.Key;
import javax.crypto.Cipher;
import javax.crypto.spec.SecretKeySpec;

public class AES {
     public void run() {
         try {
             String text = "Hello World";
             String key = "1234567891234567";
             // Create key and cipher
             Key aesKey = new SecretKeySpec(key.getBytes(), "AES");
             Cipher cipher = Cipher.getInstance("AES");

         // encrypt the text
         cipher.init(Cipher.ENCRYPT_MODE, aesKey);
         byte[] encrypted = cipher.doFinal(text.getBytes());
         System.out.println("Encrypted text: " + new String(encrypted));

         // decrypt the text
         cipher.init(Cipher.DECRYPT_MODE, aesKey);
         String decrypted = new String(cipher.doFinal(encrypted));
         System.out.println("Decrypted text: " + decrypted);
      }catch(Exception e) {
         e.printStackTrace();
      }
    }

    public static void main(String[] args) {
        AES app = new AES();
       app.run();
    }
}
