1 基本分析思路
1.1 发送public请求 从后台获取公钥
1.2 用公钥加密参数作为密文载荷
2 加密逻辑分析
2.1 sign参数破解
2.2 通过webpack分析加密逻辑
2.3 代码调试
1 基本分析思路
1.1 发送public请求 从后台获取公钥
返回的公钥
1.2 用公钥加密参数作为密文载荷
这里的载荷param就是前面获取的公钥会对参数进行加密，具体哪些参数会进行加密后续告知
获取最终的相应结果
2 加密逻辑分析
我们可以根据url进行搜索
我们在setPublicKey处打上断点，刷新页面会断住
可以看到这里的r就是后端传送过来的密钥
2.1 sign参数破解
首先调试a
可以看到a参数如下，其中sign 是密文 f()(JSON.stringify(e))
我们再来看下sign需要的参数e
在看下加密函数f()
点入f函数可以看到他是一个标准的MD5加密
至此我们的sign参数就是一个MD5加密的 JSON.stringify(e)
2.2 通过webpack分析加密逻辑
我们需要分析t.encryptLong
如果直接进入函数看调试比较麻烦，所以我们可以网上看到t=new v["a"]
那v是什么呢，我们在网上看可以看到v = t("9816")
这里可以看到是使用了webpack的打包模式 我们在v = t("9816") 打上断点
在控制台输入t.m['9816'] 进入对应的函数
2.3 代码调试
我们把function A的代码和9816代码扣下来如下
这里我们注释掉t() 通过变量全局forever = g来为之后获取模块
运行报错
在头部填入window = global 再次运行
可以看到运行正常
我们尝试调用 v = forever("9816")
再次报错
我们可以加入调试代码再次运行
可以看到缺少a524模块
搜索到a524 复制到代码
接下来我们复制encryptLong函数 以及t = new v["a"]
完成后我们根据步骤2.2的截图补足参数以及自定义一个MD5加密函数
运行后报错
我们找到w的地方点进去
知道到w函数代码复制 到自己的代码里
再次运行结果正常
我们把加密逻辑封装下
最终代码如下
// https://ec.minmetals.com.cn/open/home/purchase-info
var CryptoJS = require('crypto-js')
window = global
function MD5(arg) {
return CryptoJS.MD5(arg).toString()
}
