This helps the obfuscator identify which names are "public" and should not be renamed. Use positional arguments:
: Experienced developers or hackers can often "de-obfuscate" the code by manually tracing logic or using specialized scripts.
: Encrypts string literals and numeric constants within the code, decrypting them dynamically at runtime so string-searching tools cannot find sensitive data.
Dynamic renaming can break code that relies heavily on reflection, inspection, or external frameworks (like Django or Pydantic) that look for specific variable or class names. You must carefully exclude public APIs and entry points from being renamed. Performance Overhead oxyry python obfuscator

Oxyry provides a suite of obfuscation techniques that layer security over your Python scripts.
Hides internal API endpoints, secret keys, or specific logic patterns that could be exploited. This helps the obfuscator identify which names are
def _oX1(O0O): if O0O == "SECRET_123": return True return False Use code with caution. 2. String Encryption and Encoding
Strips all documentation and developer notes to reduce context.
: It is generally optimized for Python 3.3 - 3.7 ; using it with newer syntax (like advanced f-strings) can sometimes cause bugs. Dynamic renaming can break code that relies heavily
Do not rely on Oxyry (or any obfuscator) to hide passwords, API keys, or cryptographic secrets . Use a secrets manager or environment variables. Obfuscation only slows down the attacker; it does not encrypt the data at rest.
Copy the obfuscated output into a new .py file and run it. You will see that while the logic works perfectly, the source now looks like this:
