逆向案例二十二——请求头参数加密，某省公共资源交易电子公共服务平台

网址：交易列表 - 福建省公共资源交易电子公共服务平台

想要抓取数据，进行抓包分析，找到数据包，发现请求头有加密参数Portal-Sign，返回的数据内容也进行了加密。

 

直接搜索加密参数，找到加密位置，发现是在拦截器中，那么凭经验，解密位置肯定也在下面的拦截器中。

 

打印一下参数，看有没有找对位置，发现找对了，直接进入f.getSign函数

 

打上断点，分析,发现是d函数，结果一致的。再打印一下参数。这个函数接收表单数据t,返回加密数据。

 

直接复制函数在js中，缺什么补充什么。 r["a"] 是固定值，复制下来。

 

发现u没有被定义

 

找到u函数，就在d函数上方，复制下来。

 

然后接下来是l,都在更上面

接着是最重要的s函数。

进入s函数

 

发现似乎是MD5加密，我们可以去在线加密网站验证一下。加密内容是：

B3978D054A72A7002063637CCDF6B2E5BeginTime2024-01-17 00:00:00createTime[]EndTime2024-07-17 23:59:59GGTYPE1KINDGCJSpageNo3pageSize20timeType6total3556ts1721183028929

加密后结果小写之后是：

在线加密MD5结果是，发现结果是一样的：

改写最终代码，导入加密库。

            for (var e = Object.keys(t).sort(l), n = "", a = 0; a < e.length; a++)
                if (void 0 !== t[e[a]])
                    if (t[e[a]] && t[e[a]]instanceof Object || t[e[a]]instanceof Array) {
                        var i = JSON.stringify(t[e[a]]);
                        n += e[a] + i
                    } else
                        n += e[a] + t[e[a]];
            return n
        };
function d(t) {
            for (var e in t)
                "" !== t[e] && void 0 !== t[e] || delete t[e];
            var n = r + u(t);
            return CryptoJS.MD5(n).toString().toLocaleLowerCase()
        };
console.log(d(t))

// 结果为 b3cb44e0121be6814b1fa7a765ac7d93

好了，请求头参数的加密已经解决了，现在来分析返回内容的解密。加密内容再请求拦截器，那么解密肯定在响应拦截器洛，在下方疑似位置打上断点。

 

打上断点，分析参数

 

 

 

很明显b是解密函数，进入b函数，发现疑似是ASE的解密，r["e"]，r["i"]都是固定的，分别作为密钥和向量。
