Signtool GUI
This is a Qt GUI that wraps signtool.exe with an easy drag & drop approach.
Manually signing your binaries on Windows (automating it would be even better tho) was never as pleasant as dragging and dropping them into a visual user interface and selecting the code signing certificate + password and hit a button. Isn't that smooth af?
Before using this, make sure to have signtool.exe installed on your system and available in your $PATH
There is also a "verify" tab: in there you can drag & drop binaries into the list field and verify their signatures (instead of using signtool.exe verify /pa {FILE_PATH} or, even worse, executing them and checking if the Windows SmartScreen goes brr...).
This GUI's source code is GPL-3.0 licensed and available on github.com/GlitchedPolygons/SigntoolGUI - but also available for purchase on glitchedpolygons.com (ships with some cool, additional stuff, PDF files/manual, etc...).
Please consider buying it from there to support the development of nifty tools like this :)
