Building

Requirements

• Visual Studio 2022 with C++ Desktop workload
• Windows Driver Kit (WDK) 10.0.26100.0 or later
• .NET 9 SDK
• Windows 10/11 x64

Build

.\build.ps1                          # Release build
.\build.ps1 -Configuration Debug     # Debug build

The script builds all components in order:

1. Driver (KernelFlirt.sys) — C/WDM kernel driver
2. Loader (KfLoader.exe) — C console app
3. Relay (KfRelay.exe) — C console app
4. UI (KernelFlirt.exe) — C#/WPF application + SDK
5. Plugins (17 DLLs) — C# plugin assemblies

Output

bin/
  Driver/     KernelFlirt.sys
  Loader/     KfLoader.exe
  Relay/      KfRelay.exe
  UI/
    KernelFlirt.exe
    plugins/          ← all plugin DLLs
    themes/           ← 9 color theme files
    retdec/           ← RetDec decompiler
    share/            ← RetDec support files

Driver Signing

For development, run build.ps1 as Administrator — it will sign the driver with a test certificate. On the VM, enable test signing:

bcdedit /set testsigning on
