Python per-seat license protection

Question

I would like to create a per-seat licensevalidator for my python application. The python code is compiled. The goal is to prevent the costumer from sharing the application across his company.

Basic method

• Create a hash-string of the system hardware
  • How to do that?
• I will create a signature of the hash-string (license key file) and send the signature back to the user
• The application reads the hash-string and validates it against the signature

Maybe there is already a middleware solution?

Answer 1

Python is an interpreted language. That means decompiling of your code is always possible and relatively simple to do (using e.g decompyle). And as a result any protection mechanisms you'll implement can be easily turned off. So:

1. Protecting your code seems like a waste of time
2. Python seems not the right choice for writing closed-source applications
