【JS逆向一】逆向某站的加密参数算法--仅供学习参考

文章全程已做去敏处理！！！【需要做的可联系我】

可使用AES进行解密处理（直接解密即可）：在线AES加解密工具

1、打开某某网站(请使用文章开头的AES在线工具解密)：T9mpG48zIdYFB40hkjsQS4+N5rr4x4mSPHlx5EoT/+s=

2、点击右上角的登录按钮，账号随便11位即可，密码随便，验证码输入，点击登录后可在控制台的网络面板进行查看

3、ctrl+shift+F全局搜索【poaaword】，经过我七七八百天终于找到了，他在这里被加密，其中【W】参数位固定值，【l】参数为10位整数的时间戳，【a.data.password】为明文

4、我在控制台调用【K】加密函数，发现每次加密结果都不一样，要么是RSA加密，要么就是里面有时间戳，我们直接单步进【K】函数

5、通过【K】参数进来后，发现就在刚刚加密参数的下面，一大堆，好像是被拆散了，这种也看不出来是什么加密，直接扣他源代码就行

6、扣下来后直接调用运行，发现有报错，报错显示【f】参数未定义，我们去源代码瞅瞅

7、在源代码里发现【f】参数是一个key，但这也不能证明此网站的加密方法是RSA，也有可能是DES或AES，因为里面好像有时间戳，所有导致每次加密的结果都不一样，那我们直接把key复制到我们代码里

8、幺，成了，把key拿过来后，加密成功了，而且每次的加密结果都不一样，我们还差用【btoa】加密一下就欧克了，btoa是内置函数，可以直接调用，我们直接在代码里添加即可

9、看结果，加密三次都是不一样的结果，哎这就成了
