Answer 3

java的des加密我用过：
 java code:
            SecureRandom sr = new SecureRandom();//取得随即数据
            KeyGenerator kg = KeyGenerator.getInstance("DES");
            kg.init(sr);
            SecretKey key = kg.generateKey();
            byte[] desKey = key.getEncoded();
            DESKeySpec dks = new DESKeySpec(desKey);
            SecretKeyFactory keyFactory = SecretKeyFactory.getInstance("DES");
            SecretKey ekey = keyFactory.generateSecret(dks);
            byte[] des = ekey.getEncoded();//产生des密钥
            Cipher c = Cipher.getInstance("DES/ECB/PKCS5Padding");
            c.init(Cipher.ENCRYPT_MODE, ekey);//现在可以用密钥器进行加密
            Cipher occ = Cipher.getInstance("DES/ECB/PKCS5Padding");
            occ.init(Cipher.DECRYPT_MODE, ekey);//这是用来相同的des密钥解密
加密的方法为：
  CipherOutputStream cos = new CipherOutputStream(is, c);//is是一个输入流
