SOURCEdefender can protect your plaintext Python source code with AES 256-bit Encryption. There is no impact on the performance of your running application as the decryption process takes place during the import of your module or when loading your script on the command-line.

How do I hide Python code from client?

There are ways to ‘hide’ your Python source code:ship your application as . … ship your application using a packager such as py2exe (or similar). … Ship your application in a custom encrypted format; and ship a launcher, in C which will decrypt the file.More items…

Can I compile Python?

Python, as a dynamic language, cannot be “compiled” into machine code statically, like C or COBOL can. You’ll always need an interpreter to execute the code, which, by definition in the language, is a dynamic operation.

Why is Python so slow?

Internally, the reason for Python code executing more slowly is that the code is interpreted at runtime instead of being compiled to a native code at compiling time.

What is PYC file in Python?

pyc files are created by the Python interpreter when a . py file is imported. They contain the “compiled bytecode” of the imported module/program so that the “translation” from source code to bytecode (which only needs to be done once) can be skipped on subsequent imports if the . … But it’s still interpreted.
