2024.3.22: 修复无法激活的bug，提供了一键脚本。
PS：如果以前替换过公钥，需要还原一下app.asar再执行一键脚本，否则重新生成的公钥会不匹配；没备份app.asar的话建议重装最新版
Xmind是什么不用我多介绍了吧，52上已经有类似的授权分析了，只是步骤比较繁琐，还要安装nodejs解包asar文件，其实asar就是一个归档格式，python中也有类似的第三方包asarPy，懒得下载nodejs，直接用python脚本实现一键解包替换（hook文件需提前下载，文末有完整版），直接贴码：

完整包附上crack_xmind.zip (5.3 KB)
解压后执行一键脚本即可
可在线升级，升级后再次执行脚本即可
所有crack脚本均在这个项目里面（记得star哦）
