I agree with you absolutely. Maybe I can show you the purpose of Pyarmor by the following case: When we express a box, we can close this box with a lock, this equals encrypted scripts, or we just close the box without a lock. Pyarmor is just as this lock, it make the box more security, but it can not protect the box completely. -- https://mail.python.org/mailman/listinfo/python-list
