proguard VS pyarmor

https://github.com/Guardsquare/proguard (not the best but it does work)

Nice project! At Guardsquare, we have a similar project: https://github.com/Guardsquare/proguard-assembler

One of the things we use it for is testing: we can craft specific bytecode sequences that we want to test; for example, it's useful to test cases we've seen in the wild (e.g. obfuscated code) or to create a test that doesn't rely on a specific compiler/version.

An example of using the assembler from a ProGuard unit test https://github.com/Guardsquare/proguard/blob/master/base/src...

ProGuard is free and open-source; https://github.com/Guardsquare/proguard

With the upcoming release of AGP 7, ProGuard needs a new way of integrating into Android projects. Therefore, as part of the latest ProGuard 7.1 release, we developed a Gradle plugin for ProGuard. With this plugin ProGuard integrates into your existing gradle process, so that you can keep using ProGuard with AGP 7. You can find the plugin in the ProGuard GitHub repository.

Either look at Cython, or try obfuscating the code then using pyinstaller to create an executable.

There are few vendors that provide commercial python obfuscation/DRM (though see pyarmor)

You can obfuscate) your code with pyarmor.

You might need to obfuscate your code. Refer this https://pyarmor.dashingsoft.com/

the code is not encrypted, very easy to decode if you know the python language :) If you are looking for an up to date obfuscate, you can look at pyarmor. https://github.com/dashingsoft/pyarmor
