江西省技能培训平台(逆向破解登录)
登录破解(国密sm2加密方式)
请求接口
https://api.cloud.wozhipei.com/auth/user/v1/login
使用身份证和密码登录发现有password加密，好开始逆向js
全局搜索发现使用国密SM2进行加密
模拟算法

成功登录:
python
python使用gmssl，注意这里有个坑,
直接pip install gmssl 下载的版本是3.2.1的是旧版的sm2加密方式开始用旧标准的一直没校验不通过这个坑我走了好久，这要感谢我的学弟发现这个坑
有两个标准，这个网站是新标准的，如果使用旧标准的话后端无法解密导致校验不通过。
旧版3.2.1
新版3.2.2
