Question

Software testing

Good afternoon. Tell me how to create a test digital certificate for Windows 10, you need to sign a file for the test.
Task: There is an inf file, when you try to specify it, the system displays a message: The inf file does not contain information about the signature and does not allow you to put anything, even with the signature verification disabled. That's why you need to create this test signature.
