Modify to not use a random key

Question

Can anyone help me modify this program so it doesn't use a random key? I want to decrypt the password in another program, so I don't want to have to read a key file.
I've seen some forums posts doing something similar, but so far I haven't been able to successfully change mine. I don't think it would take much.
Anyway, any help is appreciated.

Here's the Encrypt code:
import java.io.*;
import java.security.*;
import javax.crypto.*;
import sun.misc.*;
public class EncryptPassword
     public static void main(String args[]) throws Exception
          if(args.length<1)
               System.out.println("Usage : EncryptPassword text");
               return;
          Security.addProvider(new com.sun.crypto.provider.SunJCE());
          Key key;
          try
               ObjectInputStream in=new ObjectInputStream(new FileInputStream("des.key"));
               key=(Key)in.readObject();
               in.close();
          }      catch(FileNotFoundException fnfe)
                    KeyGenerator generator= KeyGenerator.getInstance("DES");
                    generator.init(new SecureRandom() );
                    key=generator.generateKey();
                    ObjectOutputStream out=new ObjectOutputStream(new FileOutputStream("des.key"));
                    out.writeObject(key);
                    out.close();
          Cipher cipher=Cipher.getInstance("DES/ECB/PKCS5Padding");
          cipher.init(Cipher.ENCRYPT_MODE,key);
          String amalgam=args[0];
          for(int i=2;i<args.length;i++)
          amalgam+=" "+args;
          byte[] stringBytes=amalgam.getBytes("UTF8");
          byte[] raw=cipher.doFinal(stringBytes);
          BASE64Encoder encoder = new BASE64Encoder();
          String base64 = encoder.encode(raw);
          System.out.println(base64);
Decrypt code:

          if(args.length<1)
               System.out.println("Usage : DecryptPassword text");
               return;
          Security.addProvider(new com.sun.crypto.provider.SunJCE());
          Key key;
          try
               ObjectInputStream in=new ObjectInputStream(new FileInputStream("des.key"));
               key=(Key)in.readObject();
               in.close();
          }      catch(FileNotFoundException fnfe)
                    KeyGenerator generator= KeyGenerator.getInstance("DES");
                    generator.init(new SecureRandom() );
                    key=generator.generateKey();
                    ObjectOutputStream out=new ObjectOutputStream(new FileOutputStream("des.key"));
                    out.writeObject(key);
                    out.close();
          Cipher cipher=Cipher.getInstance("DES/ECB/PKCS5Padding");
               cipher.init(Cipher.DECRYPT_MODE,key);
               BASE64Decoder decoder = new BASE64Decoder();
               byte[] raw = decoder.decodeBuffer(args[0]);
               byte[] stringBytes = cipher.doFinal(raw);
               String result = new String(stringBytes,"UTF8");
               System.out.println(result);

Answer 1

I get errors when I'm trying to use the sample code you sent. What else do I need to import to use DESKeySpec? I tried import javax.crypto.spec.DESKeySpec.*;
When I try to compile I get this:
C:\Temp\Java>javac EncryptPassword.java

location: class EncryptPassword
DESKeySpec ks = new DESKeySpec(new byte[] { 0x01, 0x23, 0x45, 0x67, 0x89, 0xAB, 0xCD, 0xEF });
^
