MD5加密与DZ加密_JAVA_编程开发_程序员俱乐部

1.MD5加密：

class="java">public static String md64Encode(String Password){
       String newPassword = null;
       try {
            MessageDigest md5 = MessageDigest.getInstance("MD5");
            BASE64Encoder base64en  = new BASE64Encoder();
            newPassword = base64en.encode(md5.digest(Password.getBytes()));
            System.out.println("加密后为："+newPassword);
       } catch (NoSuchAlgorithmException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
       }
       return newPassword;
}

?2.DZ加密方式

??? ?方法：DZ加密就是 MD5(MD5(password)+时间戳);

public static String DZEncryption(String Password){
     String newPassword = null;
     try { 
          MessageDigest md5 = MessageDigest.getInstance("MD5");
          BASE64Encoder base64en  = new BASE64Encoder();
          newPassword = base64en.encode(md5.digest(Password.getBytes()));
          newPassword = newPassword+System.currentTimeMillis();
          newPassword = base64en.encode(md5.digest(newPassword.getBytes()));
     } catch (NoSuchAlgorithmException e) {
          // TODO Auto-generated catch block
          e.printStackTrace();
     }
return newPassword;
}

? 或者 调用MD5方法

MD5Util.md64Encode(MD5Util.md64Encode("666666")+System.currentTimeMillis())

?3.JAVA中的时间戳

??? System.currentTimeMillis();
