JAVA实现DES加解密文本文件

用JAVA实现DES加解密文本文件，简单实现图形界面，可以调用DES类对自己想要加解密的文本进行加解密。

package des;
import javax.crypto.Cipher;
import javax.crypto.KeyGenerator;
import javax.crypto.NoSuchPaddingException;
import javax.crypto.SecretKey;
import java.security.NoSuchAlgorithmException;
import java.security.Security;
import java.security.SecureRandom;
import java.io.*;
import sun.misc.base64Decoder;
import sun.misc.base64Encoder;
/**

public class DES {
     private String Algorithm = “DES“;///设置算法为DES
     private KeyGenerator keygen;
     private SecretKey deskey;
     private Cipher c;
     private String key=new String（“asdtiang“）;
     private byte[] cipherByte;
     String strMing=null;
     /**

     public DES（） {
           init（）;
     }
     public void setKey（String s）{
           this.key=s;
