# IdleFish_SellerId
探寻闲鱼SellerId加解密算法


最近一直在研究闲鱼的加密算法，无他，因为阿里的加密可以算是天花板级别的，研究和学习起来才值得。

很多人可能发现了，通过抓包得到的闲鱼数据包，sellerId等等值是加密过的。这就导致了很多人通过抓包或者协议请求得到的这部分数据很尴尬。

这个也是最近学习的研究的一个小成果了。展示：

1、先看下获取到的数据

取一部分JSON数据看下：

    "labelBucketId": "13",

}
```


可见其中SellerId部分数据，采用了一种类似Base64加密的字符串展示。

但试过的人都知道，这并不是简单的Base64加密。

2、展示效果：

Java实现，看界面就是大家都很熟的IDEA啦

撒花！！！

继续去学习了。
