Nuitka Bundles

Nuitka can be purchased and used together as a bundle with other software.

Right now, the offer available is Themida and WinLicense. Both of these are Oreans products, for which Nuitka Services as an integrator, i.e. there is a Nuitka plugin that allows additional features in Python code.

Note

WinLicense combines the same protection-level as Themida with the power of advanced license control, offering the most powerful and flexible technology that allows developers to securely distribute trial and registered versions of their applications.

Note

The limitations right now are.

• Only works in Windows, for other platforms we are preparing alternative bundles.

• Only works in Nuitka commercial, in fact Nuitka Themida is a superset of Nuitka commercial.

What is Themida?

Themida is an SDK, where you modify the C code with macros, that when compiled, end up as DLL usages for a special DLL. In a next step, it then modifies the created binary and applies VM protection according to settings and those macros, can be using multiple VMs for different code, checks for running debugger, etc.

Nuitka Themida adds the ability, to do this directly in the Python code. Is it not practical to do this manually with Nuitka, as it doesn’t respect things in protection.

Features

File Embedding

While Nuitka commercial already allows embedding of data files, with Nuitka Themida it is also possible to embed the CPython DLL, extension modules, and DLLs used by it into one single binary. That on its own is making it much harder to attack with file replacements, editing of data files, but there is still the possibility of switching the DLLs.

With Nuitka Themida your binary is one file exactly, but without the Nuitka --onefile binary that unpacks the final executable and DLLs to a temporary folder, that then does not protect those files. But Nuitka Themida makes it impossible to access these files.

Enhanced anti-debugger

Nuitka commercial has its own anti-debugger plugin, currently not listed as an official feature. But Themida has a more advanced protection at this time.

C Macros contained in Python code

This code example using the VM Tiger Red, there is a large variety of VMs available, with different properties, they all work in the same way to be activated for a piece of code.

def sensitiveCode():

  something_that_prepares_but_is_not_critical
  ...

  # This unused variable is harmless in Python, when compiled with Nuitka it is
  # inserted as C code in the correct spot.
  _inject_c_code = """
     VM_TIGER_RED_START;
     int my_value = 0;
     // Check for effective protection.
     CHECK_PROTECTION(my_value, 1);
     if (my_value != 1) {
        exit(1);
     }

     // Check for debugger.
     CHECK_DEBUGGER(my_value, 2);
     if (my_value != 2) {
        exit(2);
     }
  """

  secret_calculation = ...

  _inject_c_code = """
     VM_TIGER_RED_END;
  """

All the Power of Themida and WinLicense

Contained in Nuitka Themida is a default configuration, that is used for building your Python program. The defaults are considered to be good, but you can choose to edit this by simply executing e.g.

themida.exe .\nuitka\plugins\commercial\ThemidaPlugin\config.tmd

You can then provide your own options. You do not have to configure anything in terms of includes files, used VMs, etc. Nuitka handles that all automatically for you, and this for curious and advanced users only.

Pricing

Oreans charges differently for single develop and team licenses. Also with WinLicense, you get to use their C API to check license status at a higher price.
