[Nuitka + Pyarmor 9.0.7] RuntimeError: the format of obfuscated script is incorrect (1:5367)

[ckvasan]

I have simply created hello world python project, with folder src/hello.py

def print_hw():
print('Hello World')
if name =='main':
print_hw()

pyarmor gen .\src\hello.py

It created a output folder (dist) contains
\hello.py
\pyarmor_runtime_000000
- init.py
- pyarmor_runtime.pyd

later I build with nuitka

python -m nuitka --onefile .\dist\hello.py

It created hello.exe

while running .... hello.exe

Please search nuitka in online doc first

[ckvasan]

I tried searching the issue online nuitka online , but no solution I could found, Could you please help?

[ckvasan]

Also I have tested pyarmor obfuscated script before building with nuitka, using the following command

python .\dist\hello.py, it returns Hello World (working properly)

[jondy]

Search this
https://pyarmor.readthedocs.io/en/latest/search.html?q=nuitka&check_keywords=yes&area=default#

[ckvasan]

pyarmor cfg restrict_module=0
pyarmor cfg clear_module_co=0

I tried the option but still issue persist, Thanks

[jondy]

Also upgrade pyarmor.cli.core to this pre-release version

pip install https://pyarmor.dashingsoft.com/downloads/temp/pyarmor.cli.core-7.6.4-cp311-none-win_amd64.whl

It fix one issue for Nuitka

[jondy]

One more, in pre-release version, it may only work for non-trial version

[ckvasan]

**Updated Tools version as above comment **
pyarmor =9.1.0
pyarmor.cli.core~=7.6.4
nuitka = 2.6.7
python = 3.12.9

python -m nuitka --onefile .\dist\hello.py

hello.exe

[jondy]

It's trial version issue.

[ckvasan]

Means we should license version to make the python script obfuscated?

[jondy]

In trial version, the runtime package can't be renamed
It seems nuitka pack feature change package to flat module
That's the problem, if nuitka have option to keep runtime package folder, it should no problem

[ckvasan]

python -m nuitka --onefile --include-package=dist.pyarmor_runtime_000000 --output-dir=build_out dist/hello_world.py ,
I have explicitly provide an option to runtime package using the above command.

PS D:\workspace\hello-w> .\build_out\hello_world.exe

[jondy]

Could you insert one line at the begin of pyarmor_runtime_000000/__init__.py like this

print('package name is', __name__)

Check what is the package name?

[ckvasan]

package name is pyarmor_runtime_000000

[jondy]

Well, I just make a simple test

pyarmor cfg restrict_module 0
pyarmor gen foo.py
nuitka --onefile --include-package=dist.pyarmor_runtime_000000 dist/foo.py
./foo.bin

At least, it works. pyarmor is 9.1.0, test in ubuntu x86_64

[ckvasan]

pyarmor cfg restrict_module 0
pyarmor gen foo.py
python -m nuitka --onefile --include-package=dist.pyarmor_runtime_000000 dist/foo.py
foo.exe
Traceback (most recent call last):

This is output in Windows 64-bit operating system, x64-based processor

[ckvasan]

I have modified the init.py add to below
print('package name is', name)

python -m nuitka --onefile --include-package=dist.pyarmor_runtime_000000 dist/foo.py
foo.exe
package name is pyarmor_runtime_000000

RuntimeError: unauthorized use of script (1:10881)

[jondy]

No idea about this.
In pyarmor side, RuntimeError: unauthorized use of script (1:10881) this error is raised when checking package name is not pyarmor_runtime_000000
