If you want to turn your python procedure into a signed executable in Windows, just follow the steps below. Note that the strings with captial letters should be changed according to your taste.

Requirements

• Python
• Windows 10 SDK for singtool.exe

Procedure

1. install pyinstaller

   pip install pyinstaller
   

2. create an .exe from a .py

   pyinstaller /PATH/TO/FILE_TO_COMPILE.py --onefile --noconsole
   

3. create a personal certificate New-SelfSignedCertificate in PowerShell

   New-SelfSignedCertificate -DNSName "YOURDOMAIN.COM" -CertStoreLocation Cert:\CurrentUser\My -Type CodeSigningCert -Subject “MY PERSONAL CERTIFICATE”
   

4. sign the .exe with signtool or other GUI supporting tools

   signtool sign /a "/PATH/TO/FILE_TO_SIGN.exe"
   

Additional remarks

• In the step #2, --onefile allows pyinstaller to generate only one file, which is an .exe, rather than any others, and --noconsole blocks the console window while executing the .exe.
