This tool can test if a hash was created on a specific server
Start your server using py Server.py (elevated) or on Linux sudo python3 Server.py
(If you want to change ports or IPs, do this in the Server.py at the very top. The variables are called host and port and their defaults are localhost or 0.0.0.0 (you probably shouldn't change the host, if you don't know, what you're doing) and 9999 for the port.
As you can see, a file called secret will be created on the server. DO NOT SHARE THIS or people will be able to clone your server's integrity keys!
Now simply run the file called Client.py (for commands check the server part above) and everything should work perfectly fine. If you changed variables for the server, you need to do this here as well.
