Kucher is a configuration, management, and diagnostic GUI tool for the Telega motor control platform.

Kucher is an open source product distributed under the terms of the GPLv3 license.

Kucher is cross-platform. It is designed to run at least on GNU/Linux and Windows; it is also compatible with some other platforms, such as OS X, but is not actively tested against them.

Kucher installation and setup instructions can be found at the Telega home page. If you don't see a version suitable for your OS published there, please open a ticket. Links to usage instructions and examples can be found there as well.

The CI builds redistributable release binaries automatically. Follow the CI status link from the commits page to find the binaries for a particular commit. The Linux binaries can be shipped directly; the Windows binaries must be signed first.

Requirements:

• Windows 10
• An unsigned executable file named Kucher.exe
• Certum cryptographic card (USB dongle), with a valid certificate installed
• Signtool: available in Windows development Kit

1 - Connect the USB dongle to the PC. Open it, launch "Start.exe", click "Install Code Signing" and follow the instructions. Reboot the system if required.

2 - Launch proCertum CardManager. Click "Options" and tick the box "EV Code Signing - replace CSP with minidriver library". Click "Ok" and reboot the system.

3 - Make sure that signtool is included in the Windows PATH variable. Its path usually is C:\Program Files (x86)\Windows Kits\10\App Certification Kit.

4 - Open command prompt and use this command the executable's directory:

signtool sign /n "Open Source Developer, Pavel Kirienko" /t http://time.certum.pl /fd sha256 /v Kucher.exe

Enter the card's PIN when asked. The executable should now be signed.

5 - To verify the file, use:

signtool verify /pa Kucher.exe
