Stop Hackers By Using Cython (yes, Cython with a C) - Sell Your First Python App
Тәжірибелік нұсқаулар және стиль
YARRR MATEY! Avast, our app is ripe for plunder and a filthy batch of bilge rats have started clawing away at our source code. Ready the Cython cannons and prepare for battle, else ye walk the plank.
Ignoring my cringe attempt at writing a pirate-themed description, in this video we take a look at how to compile a Python executable, both with and without Cython obfuscation, and implement a simple automation process for protecting our source code. We also take a look at how bytecode can be extracted from executables, and then decompiled to recover the original source code. Scary right 😱! Lastly, we end the video with a brief discussion about the harsh reality of trying to lock down and license a piece of software which is distributed to end users for offline usage.

Subscribe!! I’d hate for you to miss my next upload :D
It would be very helpful to include a video focusing on performance aspects, such as speed optimization or insights into loading screens when using PyInstaller. And just want to express my deep gratitude for the free content you provide. and I truly appreciate the knowledge and skills you share with us. Thanks you a lots
Bruv this video is top tier. I sincerely hope your account grows to million subs.

Much appreciated Muhammad! Thanks for watching, and stay tuned for more content. :D
Great and professional videos man! Could you make a separate video on how to aggregate multiple files into one single file like you mention at 7:47 ? Would love to know how to do this more automated than manually copy-paste into a new file each time I need to build.

Thanks for watching! More content is on the way :D
Can we talk about the file size? does te cython make the binary size big? because in Nuitka the filesize got so big. or we can just stick to pyInstaller and obfuscate the code right?
Definitely worth watching content, keep going!!

Hey Yassine! Thanks for the kind words, I really appreciate it! Have an awesome day (or night) :D
i followed all your steps and it's just creating a __init__.py folder inside my project module and no other files created, what am i doing wrong?
His executable here only runs on Windows OS. 😮😢😢

Hey Taominh! I'm not totally sure what you mean by "compiling multiple files". Perhaps you could elaborate more? In this video, our goal is compiling our .py files into .pyd binaries to obfuscate the contents of our code. We achieve this by tracking all imports in our .py files (lines starting with "import" and "from"), converting our files to .pyx files, and then compiling our Cython extensions (i.e. compiling our binaries). To include other files as part of the compilation, focus on the "setup()" command called around 5:50, and how the "extensions" variable is constructed using a breadth first search (BFS) traversal of .py files to locate import lines.

please provide codes
Stop fussing around and use Rust, C++ or C.
