JavaScript逆向之iwencai请求头参数加密过程解析

打开开发者工具，在搜索框中随便输入关键词，看流量包。
（如果想将开发者工具的位置进行变换的，可以点击三个点进行切换）
只有一条数据包，看看请求数据和响应数据。
请求头中有一个特殊的Hexin-V，它的值与Cookie中的v的值一样，这个值很明显是被加密过的；响应数据包中全是明文。所以我们的目标就是搞清楚Hexin-V的值是怎么生成的。由于该值会赋值到cookie中，可以采用hook技术，这里先介绍一个google插件。
安装好之后，有以下几个功能，我们勾选Hook SetCookie，调试的时候就会停在给cookie赋值的地方。
刷新页面（ctrl+shift+r），停在了如下处。
但不是给v变量赋值，继续放，一直放到能看到那串加密的数据。
这时候我们就需要往上找，看这串加密的数据是如何加密的。查看调用栈，一个一个往上找。
还是加密的，继续向上找。
这里的n变量是通过rt.update()函数生成的，去看具体代码实现。
主要的实现代码在O函数里，发现里面全是在调用函数，所以取巧的办法是可以把相关的js代码全部弄下来，这样就不用理解它的实现逻辑了。
D函数和O函数是同一级别的，看下它们在哪个函数下面。
在一个自运行函数下面，把这个自运行函数的代码收一下，就可以看到清晰的逻辑。
变量rt就是自运行函数里的变量n，所以给n赋值也就相当于给rt赋值。从下面这行代码也能得到D函数确实是给rt更新赋值的。
将整个自运行函数复制下来，运行一下，报错了。
e没定义，往上找。
这四行代码也复制下来，又发现上面还有一个更大的自运行函数。
把代码收一下，看一下逻辑。
这样子就可以看到n的值是一个列表，那么r、e、a三个的值也就是这个了。把作用域最大的这个自运行函数复制下来，到目前位置，js代码如下：

运行，发现没定义document。
所以我们得在自运行函数的外面定义一个document，var document = {};
再运行，没定义window。
那就再补个window的定义。var window = {};。运行，没定义En。
去前端代码中找。
把整个定义变量的语句都复制出来，再运行，没定义Wn。
运行的时候，只要碰到xxx is not defined只需要找到定义补齐即可。下面出现这种错误的地方我就不一一找了，注意，复制出来的代码的顺序跟前端的代码顺序一致即可。
到目前位置，代码如下：

运行，出现如下错误。
定位到地方，Kn = c[66][f + l] || r[51].getElementsByTagName(p + d)[r[52]]，但是在我们的代码中根本没用到Kn这个变量，所以直接把这行代码删除即可。再运行，报了如下错误。
没有getCookie函数，看下包含这个函数的地方。
这个函数会先去获取cookie，如果获取不到，就会随机生成一个。既然如此，就让他直接随机生成一个就好了，只留下S[l] = Jn.random()即可，其他代码可删除。再运行，报了如下错误。
navigator没定义，我们直接去console中输出一下，如果是个定值，直接替换一下就可以了。
定值，直接替换，下面几行的也是同样道理，直接替换即可。
再运行，nt未定义，处理方法跟刚刚navigator的一样。
再运行，还是变量未定义，继续找补齐即可。全部补齐后的代码如下：
