先试用sudo arsene

Hi my friend Icex64,
Can you please help check if my code is secure to run, I need to use for my next heist.
I dont want to anyone else get inside it, because it can compromise my account and find my secret file.
Only you have access to my program, because I know that your account is secure.
See you on the other side.
Arsene Lupin.
