关于大数据:抖音Xgorgon算法0408版设备注册加密算法-抖音协议抖音爬虫-实现

抖音 app 版本更新贼快，虽说小版本之前加密算法根本一样，但还是有稍微差别。今日实现了 120601 版本（貌似 9 月初公布）的 Xgorgon 加签及设施注册的加密。通过 Xgorgon 可失常爬取到数据，通过设施信息的加密可注册到新的设施号（device_id）。

一、反编译 APK（Xgorgon）

1、jadx 关上 apk 并搜寻 xgorgon，可定位到 init_gorgon

2、读 init_gorgon() 外面的伪代码，你会发现最新版在调用 native 前所进行的一系列操作，和老版本无二，那就依照老版本操作即可；
3、再读伪代码，会发现 byte[] r0 = com.ss.sys.ces.a.leviathan(r14, r10, r0)，这个就是调用本地 so 库进行最终的加密

4、发一个最终成果看看（爬取视频的评论列表）

二、反编译 APK（设施注册明文加密）

1、jadx 关上 apk 并搜寻 EncryptorUtil，可定位到 ttEncrypt

2、读代码，能够看到调用 native 传入了两个参数，一个是 bArr(即明文压缩后的 byte)，还有一个是 bArr 的长度。至于传入的 bArr 是什么，间接 hook 就行了；
3、再发一个最终成果看看（注册 device_id）
