[BUG] Runtime License Key not found when using MultiPythonPlugin and Cross-Platform

[fadebek]

Hi, when I run my obfuscated script that needs a runtime license key, I have to explicitly set the PYARMOR_RKEY path to the location of the key. However, in the docs, it says that I should be able to just drop it in the runtime folder, but that doesn't work. Is this expected?

Steps to reproduce (using examples/testpkg):

1. pyarmor cfg plugins=MultiPythonPlugin
2. pyarmor gen -i -r --outer testpkg/mypkg -O obfpkg --platform darwin.aarch64 --platform linux.x86_64
3. pyarmor gen key -e .1 -O obfpkg/mypkg/pyarmor_runtime_005114
4. cp testpkg/main.py obfpkg
5. python obfpkg/main.py

Yields RuntimeError: missing license key to run the script (1:10601)

However, if I do PYARMOR_RKEY=obfpkg/mypkg/pyarmor_runtime_005114 python obfpkg/main.py then it runs fine.

This is on PyArmor 8.4.3 on M2 Mac. Python 3.10. Thanks

If enable MultiPythonPlugin and multiple platforms, it need copy key file to each sub-folder. For example,

cp obfpkg/mypkg/pyarmor_runtime_005114/pyarmor.rkey obfpkg/mypkg/pyarmor_runtime_005114/py310
cp obfpkg/mypkg/pyarmor_runtime_005114/pyarmor.rkey obfpkg/mypkg/pyarmor_runtime_005114/py311
cp obfpkg/mypkg/pyarmor_runtime_005114/pyarmor.rkey obfpkg/mypkg/pyarmor_runtime_005114/py312

I'll documented it.

The other solution is to customize keyname with prefix ../, so the obfuscated scripts will search parent folder of py310.

For example,

$ pyarmor cfg outer_keyname=../pyarmor.rkey

# It's better to use +, do not disable the default CodeSignPlugin
$ pyarmor cfg plugins + MultiPythonPlugin                          

$ pyarmor gen -i  -r --outer testpkg/mypkg -O obfpkg --platform darwin.aarch64 --platform linux.x86_64                             

# make sure keyfile is stored at runtime package
$ pyarmor gen key -e .1 -O obfpkg/mypkg/pyarmor_runtime_005114/py310

$  cp testpkg/main.py obfpkg                                      
$  python obfpkg/main.py

Thanks. The first method worked. The second method gave me RuntimeError: unauthorized use of script.
